The eibabo online catalogue offers a wide range of circuit breakers in the field of electrical distribution installation. All non-adjustable power switches are called circuit breakers are. Circuit breakers are also called protective switches or 'Miniature Circuit Breakers' (MCB). Also common are designations such as cutout or fuse. All these terms refer to an overcurrent protection device in the electrical installation in low voltage systems. Circuit breakers protect cables against damage caused by heating resulting from too high current, usually following a short circuit. The circuit breaker is a reusable, non-self-resetting fuse. Also available are combinations of a circuit breaker (MCB) with a residual-current device (RCCB) called RCBO devices ('Residual current operated Circuit Breaker with Overcurrent protection'). The miniature circuit breakers available at eibabo do not only differ in their rated current and design but also in the trigger characteristics. Currently, the following standardized trigger characteristics in circuit breakers are approved: B (standard line protection), C (higher inrush current in machines or lamp groups), D (for highly inductive or capacitive loads, for example in transformers, magnets or capacitors), E (SLS / main circuit breaker), K ((for high inrush current and sensitive overload triggering) and Z (semiconductor protection with high system impedance). When planning and installing electrical distribution systems, it should be noted that circuit breakers are compulsory for lighting and socket circuits in flats and residential houses and must be used. In contrast to the requirements on the circuit distribution of residential installations, industrial installations such as plants and workshops have higher requirements on the miniature circuit breakers, because here, circuit breakers / MCB often also protect facilities and machines. We at eibabo provide only high-quality circuit breakers made by known and reputable manufacturers like Siemens, ETA, ABL Sursum, ABB Stotz S & J, Eaton, Hager, Schneider Electric or Moeller, Doepke und Stahl.
