Trip Circuit Supervision is used for monitoring healthiness of the circuit
breaker (CB) trip circuit, CB trip coil.TCS is designed for the supervision of trip
circuits and other important control and monitoring circuits.The injected
current is sensed by two opto-couplers.The circuit drives a small current
through the breaker trip coil and monitors it continuously. If there is any failure
in the trip circuit or trip coil circuit, the relay will sense and operate its output
contacts. About 500ms delay is introduced to prevent false indication during
circuit breaker operation.Atest button is provided to test the relay contacts for
trip in healthy condition only. ANSI – 74TC, Rated Voltage – 9V-35V DC.
