Combination rcd-line protection - What are the advantages of a residual current circuit breaker in combination with line protection? Where are these devices used? What specification should you look out for? Read this post to learn more. Electricity is an indispensable part of our life. But the fact is that electricity poses a risk to life and property. The main risks associated with electricity include electric shock and fire. Therefore, you should not be neglectful when protecting your circuits. The aim is to protect people from the risk of electric shock and fire. In the event of sudden ground faults, a residual current circuit breaker is particularly helpful. This ensures that in such cases the circuit is immediately interrupted. Circuit breakers are used in the event of overcurrents. With the combination of both devices you protect yourself against most dangers.Image: Hager ADZ316D residual current circuit breaker with line protectionWhat is combi FI line protection?Combination switches for residual current circuit breakers (FI) and line protection (LS) are also referred to as FI/LS combination switches. This FI/LS combination switch is a protective switching device that combines the functionalities of residual current circuit breakers and miniature circuit breakers. A residual current circuit breaker is an important safety measure when it comes to protecting electrical circuits. RCCB or RCD is also often mentioned. These are the abbreviations for the English terms 'Residual Current Circuit Breaker' and 'Residual Current Device'. It is a current sensing device that can automatically measure and disconnect the circuit. Disconnection occurs when a fault occurs in the connected circuit or the current exceeds the rated sensitivity of the device. Miniature circuit breakers are overcurrent protection devices when used in low-voltage networks. These are also called MCBs. MCB is the abbreviation for the English term 'Miniature Circuit Breaker'. Advantages:The combination FI line protection devices offer the following protection at the same time: short-circuit protection, overload protection, additional protection or error protection, protection against electric shock and preventive fire protection. While a residual current circuit breaker is only used to protect against earth faults and a miniature circuit breaker only to protect against overcurrent, the combination FI line protection protects against both types of faults.Where is combined RCD line protection required?The FI line protection combination devices we offer are used both in residential installations and in industrial applications. You can significantly increase the availability of a system with RCBOs. We recommend fitting a combi RCD to each individual circuit. Errors that occur in one circuit therefore do not impair the functionality of the other circuits. Assembly:The series installation devices are intended for installation in electrical distribution boards on the DIN rail. If you have electrical circuits that must remain functional at all times, a combi FI circuit breaker is the right choice. For example, think of the power supply for your aquarium, freezer or fire alarm. RCDs and miniature circuit breakers can still cause a power outage because they only detect one type of problem. In less important circuits, a residual current device or a simple miniature circuit breaker may be less expensive. However, consider their disadvantages when installing in critical systems.Can I replace a simple residual current circuit breaker with a combination FI circuit breaker?You can, of course, retrofit an FI/LS combination switch or replace your existing residual current circuit breaker with a combination FI circuit breaker. The prerequisite is that the cable sizes are appropriate considering the rating of the combined RCD. We recommend that the replacement be performed by a qualified electrician in accordance with the manufacturer's instructions and guidelines. He should check the resistance values and test the insulation. The isolation of the RCD combination switch should also perform within the appropriate specifications.What should I look out for when buying a combi RCD?When distinguishing between the individual RCBOs, please consider the tripping characteristics. Combination switches with B characteristics and C characteristics are available here. The key difference between Type B and Type C devices is their ability to tolerate surge currents without tripping. These are typically inrush currents in connection with reactive loads, which occur, for example, with lighting or motors (capacitive or inductive loads).Good to knowThe classification according to tripping characteristics is based on the nominal residual current at which instantaneous tripping occurs. This is usually less than 100 milliseconds. On the one hand, devices with high inrush currents should not trigger the RCBO combination switch unnecessarily. On the other hand, it should switch safely in the event of a short-circuit current.Type B devices are primarily suitable for domestic and light commercial applications. Here shift shocks are low or non-existent. Choose Type C equipment for commercial and industrial applications when you expect a certain level of electrical inrush current. In addition, there are devices of type D. These have only limited applications. Typically in industrial environments where high inrush currents are expected.Type B devices trip at fault currents that are three to five times the rated current. For example, a 10 amp device will trip at 30-50 amps.Devices with a C characteristic are designed in such a way that they trip at five to ten times the nominal current. A 10A device will respond at 50-100 amps. Choose a suitable model from a trusted manufacturer. The switching properties of cheap no-name devices can differ significantly from the specified values. Don't compromise on your own safety. In this catalog from the eibabo® shop you will find numerous residual current circuit breakers with line protection from leading manufacturers such as ABB, ABL, Busch Jaeger, Doepke, Eaton, Hager, Legrand Bticino, Schneider Electric and Siemens.Why does my combi RCD keep tripping?In addition to natural inrush currents, failure of connected equipment can trip a Type B combination switch in a residential or commercial environment. This is caused by high arc currents occurring at the time of failure. If unwanted trips persist, a Type-C device can replace a Type-B device, especially in commercial applications. Alternatively, it is possible to use a type B device with a higher power rating. Another reason can of course be a constantly present fault current in the installation or in the connected devices. Connected pluggable equipment should be removed in order to identify a defective device as the cause. If this is not the case, an electrician should be commissioned to check the electrical installation immediately. TIP:If a combination FI line protection trips, there is a reason. Increasing the tolerance threshold is only possible within certain limits. In this case, please look at your installation. The normal ratings for cables and wires refer to continuous operation under specified installation conditions. Of course, cables and wires can carry higher currents for a short time without being damaged. If the load becomes too high, please secure individual devices separately.  Catalogue content:In this eibabo® catalogue Circuit breakers and fuses > Earth leakage circuit breaker you will find items from the following product groups:Item overview:Circuit breakerCombination circuit breakerCombination switchEarth leakage circuit breakerLine protectionPersonal protection machineResidual currentfrom the following manufacturers:Manufacturer overview catalogue Combination rcd-line protection:ABBDoepkeEatonHagerSchneider ElectricSiemens
Power switches motor protect. - Do you want to protect an electric motor from damage caused by overload or short circuits and need a motor protection switch for this? In this catalog from the eibabo® shop, we present a wide variety of circuit breakers for reliable motor protection. Read here how to find the right device and what you should pay attention to when buying it.Large machine parks are in operation, especially in industrial production. A correct function before and also after unforeseen events is of the utmost importance here. But even on a small scale, the electric motors used should function stably. For this reason, machines are protected against disturbances in the power supply and against overloads. Such errors occur, for example, due to improper maintenance, leaks, wear and tear or simple short circuits. Constant protection of the health and life of machine operators is just as important. Therefore, electricians and occupational safety specialists pay close attention to the implementation of all necessary measures to maintain business operations and protect employees. Motor protection switches are a component of such a safety package.What is a motor protection circuit breaker?The motor protection switch is a switching device for controlling the electric motor. The device serves to switch on, switch off and conduct current in the normal state of the circuit. The switch also has the task of automatically switching off the engine in emergency situations. The main function of motor protection switches is to protect devices from overload and short-circuit currents. When the rated current is exceeded, the circuit breakers shut off the power, ensuring the safety of electrical equipment and people.What is meant by thermal and magnetic motor protection?The tripping characteristic of a circuit breaker for motor protection is usually based on built-in thermomagnetic protection. This standard includes:protection against short circuits via a magnetic circuit breakerprotection against overload by means of a thermal circuit breaker  TIP:For safety reasons, we recommend always choosing a combined motor protection switch with both types of protection. The magnetic circuit breaker for short-circuit protection must respond quickly in the event of a high current. This type of protection is precise, reliable and economical. Ambient temperature changes do not affect tripping characteristics. Compared to thermal circuit breakers, magnetic circuit breakers have more precisely defined trigger parameters. The magnetic circuit breaker uses an electromagnetic mechanism. This is dimensioned differently according to the respective performance specifications of the motor protection switch. When the current reaches a certain threshold, the circuit is immediately broken. As a rule, this is set in such a way that tripping only occurs at ten times or more than the normal operating current of the motor. This avoids tripping during normal engine starting.The thermal circuit breaker for overload protection reacts with a delay because a motor usually draws a higher current when starting. This type of protection is one of the most reliable and economical types of protection for electric motors. These handle high starting currents and protect the motor from failures caused, for example, by a blocked rotor. The thermal overload protection works with a bimetallic strip. Deformation occurs when the bimetal is heated to a critical temperature by the current flowing to the motor. This indicates that the power consumption is continuously too high. The motor is under excessive load and may stall or otherwise fail. A special feature of thermal circuit breakers is their temperature compensation. In this way, a precise triggering behavior defined according to the respective calibration is guaranteed at different ambient temperatures.Image: Eaton PKZM0-1 motor protection switchWhat circumstances can cause a motor protection switch to trip?A wide variety of faults can occur during the operation of an electric motor. It is therefore important to be aware of these dangers, assess the probability of failure and anticipate possible causes. In this way, a motor can be optimally protected. An electric motor can fail or be damaged under the following conditions:Poor power quality due to high voltage, under voltage, surges, frequency change, incorrect installation or malfunction of the electric motor itselfGradual increase in temperature or reaching and exceeding the permissible limit values due to frequent switching on and off, insufficient cooling, high ambient temperature, reduced atmospheric pressure, high temperature of the working medium or excessive viscosity of the working mediumSudden rise in temperature due to blockages in the motor drive or phase failure Where are motor protection switches installed?The most common motor protection switches are designed as built-in devices. Alternatively, depending on the model, it can be installed in the control cabinet on the DIN rail. Mounting directly on the machine is obvious, because a machine is usually switched ON and OFF via the motor protection switch. Manual power on is done by pressing the start button labeled 'I' or '1'. Depending on the version, this can also be a rotary switch. Manual shutdown is done by pressing the stop button or turning the switch position back to '0'.What should be considered when selecting a motor protection switch?Basically, when selecting a circuit breaker for motor protection, you should be guided by three criteria: the rated current, the overload current and the short-circuit current. The rated current of the machine is the maximum allowable current at which the circuit breaker can remain on indefinitely. However, it is of no use if the switch is correctly selected in terms of current rating, and the wiring does not withstand the load, melts and causes a short circuit. Choose the motor protection switch not only according to the nominal power of the machine, but also the cable cross-section and the quality of the wiring. Thermal overload protection suitable for your system and magnetic protection against short circuits should be considered on the same premises.Notice:With motor protection switches, a mechanical load on the device cannot be ruled out. The switches are therefore often made of very robust and self-extinguishing plastic.When buying, make sure you choose a brand you trust. A motor protection switch must function reliably and, in an emergency, have the declared properties. This cannot be guaranteed without a doubt for no-name items. The price difference to a high-quality original is not that big when you compare the safety of man and machine. Therefore, opt for products from trusted manufacturers such as ABB, ABL, Condor, Eaton, Hager, Helios, Maico, Rockwell, Schneider Electric, Siemens and Stahl.Convince yourself of the quality of our articles.

Charging device e-mobility - How do I charge an electrically powered car, motorcycle, bicycle, scooter or skateboard? Which charging station is the right one for my vehicle? Find out here which requirements must be met for the installation of a charging station. We support you in the purchase decision and clarify frequently asked questions. Charging stations for electromobility are an investment in the future. The demand for electric vehicles is constantly increasing. Soon they will account for a massive share of the new vehicle market. Now is the ideal time to invest in charging stations. While the cost of electric vehicles is falling, the range is constantly increasing. This means that more and more people will be able to drive their entire journey in an electric vehicle. The increase in electric vehicles is also associated with an increased need for charging stations. If you would like to charge your vehicles at home or at work in the future, you will find suitable offers for high-quality charging stations in the eibabo® shop with which you can maintain your electric mobility.What is a charging station?A charging station connects electric vehicles to a power source. These are mostly electric cars. In the private sphere, such a device is also called a wall box. This provides the energy required to charge a battery. A distinction is made between AC chargers and DC fast charging stations. You can only charge a battery with direct current. The electricity from the socket is available as alternating current. For this reason, most electric vehicles have their own charger or charging cable with rectifier. This converts the alternating current into direct current. DC quick chargers are mainly found in public spaces. These enable charging with higher power. The direct current is supplied directly to the battery. The vehicle's converter is bypassed. There are simple and inexpensive models, but also extensively equipped variants. Some have smart meters, connectivity to cellular networks, or internet access. TIP:Many charging stations have a residual current circuit breaker. This saves you the cost of an external residual current device. The eibabo® shop not only has charging stations for electric cars, but also for electric bicycles.Why should I invest in a charging station?More and more people own an electric car. If you invest in a charging station, you can use it in your private environment or, for example, offer it to the residents of your building as a landlord. In private use, you make yourself independent of public charging stations. You determine the cost of charging yourself by choosing a cheap energy supplier. There is also the option of connecting your own photovoltaic system. How to use your self-generated solar power to charge your vehicles. There are also many advantages for commercial use. For example, you can encourage your customers to charge their car while they shop. This extends the parking time and can attract new customers.What should I consider when buying the charging station for my electric car?Have the installation carried out by a specialist electrician.Define your equipment requirements before purchasing. Should it be possible to use it via a smartphone app? Do you want to record electricity costs and create statistics? Is access protection desired?A DC residual current detection integrated in the wall box reduces the costs of the house installation.When integrating into a photovoltaic system, please ensure that the interfaces are compatible.Wallboxes are usually not in permanent use. Therefore, the standby consumption should be as low as possible. Can the wallbox be switched off completely?Register the charging station with the network operator.Systems with more than 11 kW of power are subject to approval in Germany, for example.Please ensure that the manufacturer's declaration of conformity is available. This ensures that the device meets the requirements of your country.Good cable management including plug garage makes daily handling easier.A wall box with a socket should have a switchable locking device for the charging cable. This will prevent the charging cable from being stolen. Where should I install the wallbox?A wall box is best installed in a dry, shady place that is not exposed to direct sunlight. The ideal height should be around 1.5 to 2 meters above the ground. Make sure the area around the box is clear of obstacles. Depending on the installation location, the question of the correct cable length arises. It should be noted that power consumption and the associated costs increase with longer cables. Line losses may occur if the cable is too long. The recommended cable length for wall boxes is 10 meters. This is the optimal length to avoid losses and keep power consumption low.DangerThe requirements and standards that must be observed when connecting a charging station for electric cars can be very extensive. You should therefore commission a specialist electrician to do this.If you need a longer cable, you should consult an electrician. He is able to dimension the cable correctly and ensure that no losses occur.Do I need a separate charging station for my e-bike or pedelec?You can charge e-bikes and pedelecs at a classic household socket. If you live in your own house, this is possible in the garage, in the carport or in the basement. We recommend using a charging station if you regularly want to charge more than one bike at the same time. So the bikes are always in a designated place. The distribution of the wheels to several sockets in different rooms is no longer necessary. As a landlord, you can also offer your tenants the charging of their electric bicycles. As a rule, you do not have a publicly accessible socket in the underground car park or in the hallway. A charging station is a suitable alternative before the occupants of your house have to carry the electric bike into the apartment. Depending on the model, individual billing or locking of the charging points is possible.Which wall box is right for me?There are a number of factors to consider when choosing the right charging station. On the one hand, the power of the charging station should be matched to the required charging power of the vehicle. On the other hand, it is important to choose the fuse for the circuit and the dimensioning of the cable accordingly. TIP:The required charging power of a vehicle is usually specified in the operating instructions. For an electric car with a battery capacity of 40 kWh, for example, a charging capacity of 11 kW may be sufficient. Faster charging is possible if the charging station has a higher power. You can usually charge an electric car with a battery capacity of 60 kWh at a charging station with 22 kW. Circuit protection is important to prevent damage to the vehicle or charging station. The recommended fuse for a wall box with 3.7 kW power is 16 A. For a wall box with 11 kW power, the recommended fuse is 32 A and 22 kW power must be fused with 64 A. The dimensioning of the cable depends on the length of the cable and the desired charging power. For example, a 1.5 mm² cable is sufficient for a charging capacity of 3.7 kW. At least 6 mm² is recommended for a charging capacity of 11 kW. The number of charging points depends on the number of vehicles that are to be charged at the same time. If you want to charge several vehicles at the same time, there must be a separate charging point for each vehicle. The power of the charging station is divided among the vehicles. Dimension a new charging station for the future. Lay cables with a cross-section suitable for 22 kW. In this way you avoid further costs if you later buy a vehicle with a quick charging function.How do I calculate the charging time of my electric vehicle?The charging time of an electric vehicle depends on various factors, such as the battery capacity, the charging power and the discharge current. The battery capacity indicates how much electricity the vehicle's battery can store. The charging power is the maximum charging current with which the battery is charged. The discharge current is the maximum current at which the battery can be discharged. To calculate the charging time of an electric vehicle, divide the battery capacity in kilowatt hours (kWh) by the charging power in kilowatts (kW).Image: ABL 1W2221 wall boxThe following example shows how to calculate the charging time of an electric vehicle: A vehicle has a battery capacity of 24 kWh. The charging power is 3 kW. In this case, it takes 8 hours to fully charge the vehicle.What does load management mean for the charging station?A distinction is made between load management within the wall box and load management within the electrical installation. Wallbox load management has the following advantages:Optimized charging performance: Load management optimizes the charging performance of your wall box. For example, you can charge your battery faster and more efficiently.Protection of the battery: Another advantage of load management is that the battery is protected. The optimized charging performance prevents the battery from being overloaded.Maximize battery life: Since load management protects both the charging power and the battery, you can maximize the life of your battery. So you can benefit from your wall box for longer. If several smart charging stations are in use, these can be integrated into a building's load management system via additional modules. This means that several electric cars can be charged at the same time with the same connected load. The available power is automatically distributed to the number of charging vehicles. Companies, car parks and hotels with several charging stations thus avoid expensive power peaks.Do I need restricted access for my Wallbox?In many cases, the Wallbox is located in public or semi-public areas. This means that it is accessible to everyone. This can pose a security risk, especially if the wallbox is not properly secured. A lockable wall box provides an additional layer of security. Unauthorized persons are prevented from accessing it, for example in a communal garage, in a hotel car park or company car park. Another option is to connect the Wallbox to an RFID system. This means that only authorized persons can open the box and use the power plug. RFID systems can be installed either on the wallbox itself or on a separate access control system.  Catalogue content:In this eibabo® catalogue Industrial socket / plug applications > Charging device E-Mobility you will find items from the following product groups:Item overview:Bike charging stationBike charging stationsCharging caseCharging stationElectric bikeElectric bikesElectromobilitySocket housingVehicle chargerfrom the following manufacturers:Manufacturer overview catalogue Charging device e-mobility:ABLGSABHagerMennekes E-MobilitySchneider ElectricSpelsbergWalther
Distributor-timer - digital - Don't you also think that many electrical consumers don't have to be in operation all day? Would you like to save costs and conserve resources? This is possible with timers for the control cabinet. Find out here which functions digital distribution time switches can take on and which special features you should pay attention to when buying.At eibabo® you will find the right digital distributor time switch for installation in the electrical distribution board. We carry a large selection of Astro timers, weekly timers and yearly timers. Manufacturers of high-quality devices include Hager, Finder, ABL Sursum, Theben, ABB, Stotz S&J, Legrand (BT), Grässlin, Eltako and Schneider Electric. In the following text we will go into the individual variants in more detail.What are distribution timers?A time switch for the junction box is an electronic or mechanical device that switches electrical consumers on a time-controlled basis. These can be switched on and off without having to flip the switch yourself. This can be useful in private households as well as in commercial companies and in the industrial sector. The purposes of the distributor time switches include, among other things, the automatic switching on and off of lighting systems or the control of fixed house installations such as heating, ventilation, lawn sprinklers and air conditioning units. This not only saves you time, but also money.NoticeDistribution time switches are often offered in grid dimensions (pitch units). Depending on the equipment, such a device requires one to four modular widths in the control cabinet.The advantages of a timer are therefore obvious: electricity costs can be reduced effectively through the targeted control of your electrical devices. At the same time, you have the option of making your home less attractive to burglars, for example by simulating your presence using optionally available random functions.You can also get digital or analogue timers for the socket in another catalog from the eibabo® shop. Their function is comparable to that of the distributor time switches. However, the area of application extends to 'mobile' devices that are not permanently installed. These include Christmas lights, aquarium technology or decorative items such as fountains.What functions do distribution timers offer?A high-quality distributor time switch offers numerous functions and programs for the individual setting of the switching cycles. These include:60 min program / 24 h programWeekly program / annual programAutomatic summer/winter time changeoverholiday programimpulse programcycle programastro programrandom programPermanent switching ON/OFFexpiration timerhour meter Image: Theben TR 644 top2 RC distribution time switchWhat is the difference between each type of timer?We often come across terms such as astro timers, weekly timers or yearly timers. With regard to a purchase decision, the question then arises as to whether there are significant differences between these models. The basic function is the same for all models. The differences lie in the detail and the setting options of the individual variants. The astro function of a timer adjusts the switching times daily to the seasonally changing length of the day. In other words: When the days get longer in spring, the device switches on a little later every evening and a little earlier every morning. This process is calculated electronically and does not require a brightness sensor, for example, which would otherwise have to give the command to switch the light on or off. With a weekly timer, you can set individual switching times for each day of the week. In contrast, the function of a very simple time switch is limited to setting switching cycles within 24 hours.Already knew?Modern timers have a powerful power reserve. In the event of a power failure, this ensures the function of the timer for up to 10 more years.The annual time switch offers even more extensive functions. This means that different switching times can be provided for each calendar day and vacations and public holidays can be taken into account.Do distribution timers require a separate power supply?Digital timers always require energy to operate. As a rule, a distribution time switch is clamped onto the DIN rail of the control cabinet and supplied with mains voltage via an integrated power pack. Time switches that are exclusively battery operated are rare. These are typically analogue variants, which are used, for example, as 'door openers' in stables when there is no electricity.Is a digital timer always better than an analogue model?An analog timer works mechanically, a digital timer works electronically. Whether one or the other variant is more suitable for you depends on your requirements for the device. Mechanical timers usually have a higher-level switch with which you can switch the device off completely, switch it on permanently or switch it to switching mode. Switch buttons arranged in a circle represent the daily routine. There are usually 48 buttons and each button stands for half an hour. Activate or deactivate the corresponding switching period by pressing or pulling out. Compared to analog timers, digital timers offer significantly more setting options and functions. In contrast to mechanical timers, you can usually set several switching programs down to the minute over days or weeks. The distribution timer is operated using buttons and a display. TIP:If you want to control more than one device with the distribution timer, choose a model with the appropriate number of channels. This saves a lot of space in the control cabinet. Times and switching programs are clearly shown on the display. In terms of accuracy and functionality, a digital time switch is clearly superior to the analogue version. However, it requires a certain learning phase to understand the technology and set switching programs. If you only need 'rough' and daily recurring switching processes, analogue time switches are still a good alternative. These are set up and ready to use in just a few seconds.Can distributor time switches be programmed using an app or externally?There are distributor time switches that have Bluetooth and can be configured using an app. This allows you to display and change the switching states via smartphone or tablet computer. The prerequisite is the coupling between the input devices and timers within a network. Another way of programming the switching times is to use manufacturer-specific software. You can transfer the switching information to a special memory card via the USB interface of your computer. The memory card can then be connected to the time switch on the construction site/in the switch cabinet and the switching data can be loaded into the switch and vice versa.Doesn't a distribution timer consume more electricity than it saves?If the focus is on switching a consumer (e.g. the lighting) on and off, a distribution time switch is of course useful. As a rule, active end devices consume significantly more power than a timer. The question asked above relates to switching off a device that would otherwise run in standby mode for hours.To answer this question, a distinction must be made between an analogue and a digital time switch. An analogue model is less complex and usually has an output of less than 1 watt. With an electricity price of 40 cents per kilowatt hour, for example, the consumption costs are around 1 cent per day with 24 hours. With a digital timer, you have to assume around 2 watts and thus calculate electricity costs of 2 cents per day. In this calculation example, the investment costs for one or more time switches should also be taken into account.You can now compare this with the standby power consumption of your devices. This essentially depends on the type, age and number of devices. Old devices with displays consume more power in standby than modern electronics with only one control LED. A mix of new and old devices in the household currently results in an average consumption of 1 to 2 watts per device. If you need a separate timer for each electrical device, using them to save standby power is therefore not economical. The situation is somewhat different with distribution time switches, which can switch several devices or machines with a high standby current at the same time. This may save you on standby electricity costs, although this is not the primary reason for using a timer in these cases either. TIP:Pay attention to the shortest switching time of the device if you want to switch short intervals. Some devices only switch every minute and only a few devices switch every second or even faster. An example: If you have a terrarium with a sprinkler system, the nozzles should usually only spray for a few seconds. This is to maintain high humidity. Prolonged spraying may flood facility and animals.  Catalogue content:In this eibabo® catalogue Devices for distribution board- / surface mounting > Digital time switch for distribution board you will find items from the following product groups:Item overview:Astro timerBuilt-in timerDaily timerDigital timerDistribution timerEnergy efficientExpansion moduleInstallation timerJunction boxLighting controlLocation dependentPosition dataPower reserveProgram clockQuartz timerSeries installationTimerTimer moduleTimersUniversal timerWeekly programWeekly timerYear time switchfrom the following manufacturers:Manufacturer overview catalogue Distributor-timer - digital:ABBDoepkeEatonEltakoFinderHagerHamaLegrand BticinoSchneider ElectricSiemensTheben
Circuit breaker - Are you sure that your electrical installation offers correct protection against overcurrents? Errors in protection can have dangerous consequences. Read here what you should pay attention to and the importance of the high-quality miniature circuit breakers from our eibabo® online shop.The use of electronic devices is a matter of course for us. Their use is comfortable and safe. But what happens if the television, washing machine, oven or refrigerator has a short circuit or overcurrent? These devices would be permanently damaged and fire accidents would be the result if suitable protective mechanisms were not activated as quickly as possible. In everyday life, hardly anyone thinks about these dangers. Why is that? Various safety elements are integrated in today's electrical installations, which protect people, electrical devices or the circuits themselves from damage caused by overcurrent. Modern miniature circuit breakers, among others, perform this task. They are also called circuit breakers or fuses. Do you remember?Historically, fuses contained a metal wire or strip that would melt if overcurrented, interrupting the flow of current. As a result, a tripped fuse was destroyed and had to be replaced. These so-called safety fuses are still used today, for example in vehicle construction. Circuit breakers work differently, can be reactivated manually after tripping and thus offer obvious advantages over fuses.What are circuit breakers?All non-adjustable circuit breakers are referred to as miniature circuit breakers, also known as MCBs. MCB is the abbreviation for the English term 'Miniature Circuit Breaker'. It is always an overcurrent protective device in the electrical installation when used in low-voltage networks. Miniature circuit breakers protect lines from damage caused by heating up as a result of excessive current, usually caused by a short circuit. The miniature circuit breaker is a reusable safety element that does not reset itself automatically. This makes handling very safe and you can quickly restore the power supply after it has been triggered. There are no high maintenance and replacement costs. Combinations of a miniature circuit breaker (MCB) with a residual current device (RCCB) are also available, these combined devices are referred to as RCBO devices (English: 'Residual current operated Circuit-Breaker with Overcurrent protection').What were the different miniature circuit breakers developed for?The miniature circuit breakers available from eibabo® differ not only in their rated current and design, but also in their tripping characteristics. The following standardized tripping characteristics are currently permitted for miniature circuit breakers:Type B (standard line protection)Type B miniature circuit breakers are the usual variants for private use. These switch off the circuit as soon as the current exceeds three to five times the actual current flow. Type C (higher inrush current for machines or lamp groups)Type C switches are used, among other things, in household appliances and in commercial devices such as fluorescent tubes, PCs, printers and servers. These break the circuit when the current exceeds five to ten times the actual current flow. Type D (for highly inductive or capacitive loads, e.g. with transformers, magnets or capacitors)Type D MCBs offer high resistance. These turn off the circuit when the current exceeds ten to twenty times the actual current flow. Type E (SLS / circuit breakers for main lines)SLS stands for 'Selective Circuit Breaker'. This triggers with a time delay when the current exceeds 5 to 6.25 times the actual nominal current. This means that downstream fuses or classic miniature circuit breakers switch off the current beforehand. Type K (with high inrush current with sensitive overload tripping)Type K miniature circuit breakers trip at eight to twelve times the actual current flow. These protect heavy-duty equipment such as compressors, winding motors and X-ray machines. Type Z (semiconductor protection with high line impedance)Type Z miniature circuit breakers are sensitive to short circuits and are used in semiconductor production. These break the circuit when the current exceeds two to three times the actual rated current. Image: Hager MCN316 miniature circuit breaker 3-poleIs the installation of miniature circuit breakers absolutely necessary?Miniature circuit breakers for lighting circuits and socket circuits are mandatory in the circuit distributors of apartments and residential buildings. You must install these. For industrial installations, in industrial plants and in trade, please pay attention to the higher requirements for miniature circuit breakers. Here, miniature circuit breakers / MCBs often also protect equipment and devices.How does a circuit breaker work?Miniature circuit breakers usually have two trigger mechanisms, the electromagnetic quick release and the thermal release. When an overcurrent flows through the circuit breaker, a bimetallic strip in the thermal trip unit heats up and bends. This triggers an interlock, interrupting the flow of current in the circuit. This process protects against hazards or damage to devices that can result from the overload. In addition, the melting of the lines is prevented. In the event of a short circuit, the electromagnetic trigger acts. Here the current suddenly increases and a magnetic field builds up inside a coil. A bolt reacts to this, hitting the trigger mechanism in fractions of a second and interrupting the circuit.NoticeIn the circuit breaker, the outer switching lever is not directly connected to the actual switching mechanism. The device also triggers reliably if the shift lever is jammed, locked or manipulated.To get the current flow going again, the circuit breaker can be reactivated using the shift lever.What is the difference between single-pole and multi-pole miniature circuit breakers?You use single-pole miniature circuit breakers, for example, for circuits with single-phase alternating current. Three-pole miniature circuit breakers are used in AC circuits with three current-carrying phases. In the event of an overcurrent or short circuit, these are able to switch off all phases. This happens even if the fault affects only one phase. recommendationWe advise you to protect multi-phase circuits with a multi-pole circuit breaker. Do not divide the individual phases into single-pole circuit breakers. Working with electricity is dangerous. Please have changes or extensions to your system carried out by a specialist electrician.Which miniature circuit breakers are recommended?A large selection of miniature circuit breakers for electrical distribution installation can be found in the eibabo® online catalogue.
