Trip circuit supervision relay SPER 1C1
Continuous monitoring of circuit-breaker trip circuits and other essential control circuits, providing immediate information about faults
Technical Specifications
Supervises important control circuits: circuit-breakers, disconnectors, and signalling circuits
One relay per circuit; multiple relays can supervise branched circuits
Designed for COMBIFLEX system
Supply voltage range: 40–265 V DC
Continuous monitoring to prevent undetected faults
Preset operate time avoids unwanted alarms during circuit-breaker operation
LED indicator on the front panel shows relay operation
Detects bad contact, contact welding, and auxiliary voltage failures
For rail- or surface-mounted options, see SPER 1B1 C4
