Trip Circuit Supervision Relay SPER 1B1 C4

The trip circuit supervision relay SPER 1B1 C4 is used for supervising important control circuits such as circuit-breaker and disconnector control circuits and signalling circuits in power electrical installations. Generally one supervision relay is needed per circuit to be supervised. If several branches of a circuit are to be supervised, the required number of relays can be connected to the same control circuit.

The supervision relay SPER 1B1 C4 is composed of a standard 11-pin plug-in relay unit and a corresponding terminal socket for rail-mounting. The trip circuit supervision relay is also available in COMBIFLEX design, see products SPER 1C1 and SPER 1C2
