Circuit Breakers and Switches

Circuit Breakers and Switches
Circuit breakers protect electrical cables and machines from overloads, short circuits and insulation failures. Switch disconnectors switch lines on and off, mainly to de-energize and isolate a part of the network before servicing it.

● ComPacT molded case circuit breakers (MCCB) ComPacT for cable and machine protection from 100A to 3200A.
● MasterPact air circuit breakers (ACB) for the protection of low-voltage lines up to 6300A.
● Disconnectors and main switches, MasterPact, ComPact and FuPact for manual or remote-controlled switching of low-voltage lines up to 6300A.
● TransferPact automatic and manual transfer switches to change from main to backup power sources.
