Supervision & Signalling

Signalling and supervision relays are a unique part of the COMBIFLEX-S family of relays. These relays are implemented for critical circuit monitoring and signal indicators in electrical applications.

While Supervision relays are applied for the supervision of trip circuits and trip coils of circuit breakers, Signalling relays are used to provide a visual indication of the operation of protection functions and contact multiplication.

Our offering:


Type RSSF 1 is a signal flag relay intended for use as an operation indicator. The relays have manual reset or self-reset flags. A zero-voltage type is available and can be used to supervise DC supply voltages. Up to two coils are available in a single relay.
