MCB.P C-3p+N-40A, Circuit breaker
MCB-P or MCB-T are circuit-breakers that combine the functions of a circuit breaker (overload and short-circuit protection) and those of a contactor on the same element. There are two options with MCB:
The remote control function works on the same contacts as those of the circuit breaker, guaranteeing the disconnection in each case. The MCB-T type includes a remote control module with two auxiliary, potential free (three-wire) contacts that indicate the status of the MCB at the input of the remote control (contactor function) and/or the circuit breaker.
MCB are the perfect elements to guarantee self-reclosing residual current and overload protection applications, connected to WRKRT-25 relays.
