The trip circuit supervision relay SPER 1C1 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 SPER 1C1 is mechanically designed to suit the COMBIFLEX system. The relay supply voltage range is 40-265 V DC.
If a rail-mounted or surface-mounted supervision relay is required, please refer to SPER 1B1 C4.
