Abb 1myn569697-g Trip Circuit Supervision Relay

What Is a Trip Circuit Supervision Relay?

These relays exist to check the condition of a circuit breaker’s trip circuit to make sure it is in a state of readiness to function when a fault is triggered. The trip circuit comprises wiring, power supply, and the trip coil of the circuit breaker. A malfunction in this circuit can cause protective relays not to work properly — which could end up causing serious equipment damage or safety concerns.
