Our offering:

COMBIFLEX®

The COMBIFLEX portfolio consists of auxiliary, tripping, signalling and supervision relays and a variety of mounting accessories. The auxiliary relays are used as an interface between the protective relay and the circuit breaker, or as contact multiplication or signaling relays when used with protective relays or with primary equipment such as circuit breaker or isolator.

COMBIFLEX®-S

The COMBIFLEX-S family of relays have a simplified design in terms of mounting and connection. The relays can be directly flush mounted without the need for additional relay cases or equipment frames. Standard ring or fork type lugs can be used to terminate the wiring.
