Trip circuit supervision relay SPER 1C2
Continuous monitoring of circuit-breaker trip circuits and other essential control circuits, providing immediate information about faults
Technical Specifications
Supervises critical control circuits: circuit-breaker, disconnector, and signalling circuits
One relay per circuit; multiple relays can supervise circuit branches
Designed for the COMBIFLEX system
Supply voltage range: 20–60 V DC
Continuous monitoring to prevent undetected faults
Preset operate time prevents unwanted alarms during circuit-breaker operation
LED indicator on front panel with output relay for operation indication
Detects bad contact, contact welding, and auxiliary voltage failures
For rail- or surface-mounted version, refer to SPER 1B1 C4
