Installation small distributor

Do you need one or more small installation distributors at top conditions for the production of your electrical installation? The eibabo technology store offers the right machine housing for every requirement. Choose from numerous models in different sizes and for every type of installation.

 


TIP:

Calculate reserves, at least 25% additional space required. Size the distributor slightly larger. You never know if and when you might want to make more installs.


 

If there is later a need for expansion, additional slots and mounting locations for fuses, sockets or measuring devices are required.

What are installation small distributors?

A small installation distribution board is also referred to as a machine housing, power box or fuse box. There are power distributors in almost every electrified house these days. Depending on how complex a system is, there can be various sub-distributors or group distributors in addition to a main control cabinet. The safety devices, switching devices or measuring devices for a specific section of the installation are then located in these distribution boxes.

What is the function of a small installation distribution board?

A complex electrical installation must be divided into individual sections. These are individually insured. This avoids faults and short circuits affecting the entire system. Such a section can be, for example, an apartment. The small installation distribution board contains switches, automatic circuit breakers and other devices with which the electrical current is distributed and secured in the respective section. From here, the lines lead to other sub-distributors (e.g. circuit junction boxes) or directly to consumers such as sockets or lamps. Devices with high power consumption, such as electric stoves, have a separate fuse in the sub-distribution board for safety reasons. The importance of an individual distributor depends on the size of the overall system. In larger houses with multiple entrances and residential units, sub-distributors may be required for each entrance, then for each floor and then for each individual apartment.

Already knew?

A main distribution is the first distribution after the transformer station. From here, the energy is distributed to commercial buildings, residential buildings and other consumers.


Thus everything after the main distribution is a sub-distribution, field distribution or group distribution. Please refer to the product descriptions for the specifications for using the small distributors (for example: maximum rated current, number of modular units).

Why do I need a small installation distributor?

Electrical systems within a building are based on a primary sub-distribution. How useful a further sub-distribution is depends on the complexity of the system. Each installation small distributor thus serves as a node for a specific section. This results in the following advantages:

Overview and control of the subsequent installation

  • From this point it is easy to determine individual rooms. Possible errors and defects can be localized quickly. In addition, individual devices such as electric stoves or heating controls can be precisely assigned.

 

Ensuring short cable routes to the end user or to the next fuse

  • Short distances mean less voltage losses and line losses. Installation costs are lower. Maintenance work and repairs do not take that much time.

 

Possibility of individually securing or switching off an area

  • The installation after the distributor is secured separately. In the event of a problem or damage, only this area is affected without affecting the entire system.

Is the structure of a small installation distribution board standardized?

A small installation distributor is a component of the electrical installation and is subject to certain regulations and standards. In Germany, these are regulated in the DIN standard 43880. The size of a junction box can be freely selected to a certain extent and is determined by your needs. The internal structure is determined by the DIN rails on which circuit breakers, circuit breakers, sockets and other devices are mounted. The top-hat rails must be at least 150 mm apart in height. This distance may be increased in increments of 25mm if required by the installation. The DIN rail, also known as the mounting rail, is divided into 12 modules. A pitch unit is indicated in the descriptions with 'TE' and is 18 mm wide as standard. This allows the capacity of an installation small distribution board to be clearly described.

 


TIP:

The external dimensions of a distributor vary from manufacturer to manufacturer. These say nothing about how many devices you can install. The capacity of a distributor is specified in division units.


 

An example: If the description says 48TE 4x12x18mm IP54, you know that this distributor has 4 DIN rails. Each rail comprises 12 pitch units of 18 mm. The sum of the devices that you can install is 48 TE. The manufacturers follow this grid dimension and offer their modular installation devices in 1 HP, 2 HP, 3 HP and so on. The specification IP54 refers to the degree of protection. This describes how well the distributor is protected against the ingress of water or other foreign bodies from the outside. The first digit stands for foreign bodies and touch, the second digit for water. In the example given, the '5' means protection against dust and larger particles, the '4' means protection against splash water.

Which devices may be installed in a small installation distribution board?

The lines of the individual circuits come together in the small distributor. Here you can find the following built-in devices:

  • Miniature circuit breakers and RCDs/residual current circuit breakers and other switches
  • Automatic circuit breakers and fuses
  • relays and contactors
  • transformers
  • Staircase light machines
  • timers
  • indicator lights
  • Schuko sockets
  • terminal blocks
  • transducer
  • Overvoltage protection
  • programmable logic controllers
  • automation components
  • In addition, a combined installation with the electricity meter is possible.

 

Where and how can small distribution boards be installed?

A suitable installation location must be selected depending on the function performed by the distributor. The installation can be flush-mounted or surface-mounted. Flush-mounted distributors, for example, are the first choice for masonry. Surface mounting makes sense on concrete walls. A place in the house connection room should be provided for a main sub-distribution. There are usually other media such as gas and water. For additional sub-distributions on the floors or in the apartments, observe the following installation criteria:

  • Choose a suitable place with average room temperature.
  • Avoid high humidity and strong temperature fluctuations.
  • Install the small distribution board at a comfortable height. The distance from the floor to the center of the distributor should be at least 1.10 m and maximum 1.85 m.
  • Ensure there is sufficient light and freedom of movement in and around the small distribution board.
  • Make sure that the distributor is always easily accessible. This facilitates access to the installation if necessary.
