COMBIFLEX®

The auxiliary relays are used as an interface between the protective relay and the circuit breaker, or as contact multiplication or signalling relays when used with protective relays or with primary equipment such as a circuit breaker or isolator. The various accessories form a part of the COMBIFLEX building system, which offers flexibility in mounting while also maintaining a very high level of safety.

It is also possible to combine COMBIFLEX auxiliary relays with Relion® protection and control family products or other protection relays to add functionalities such as lock-out, lock-out reset, or external contact reinforcement.
