How does a relay protection system trip a circuit breaker

When the relay determines that a condition exceeds its settings or logic requirements, it sends an output signal to trip a circuit breaker, alarm an operator, block an operation, or start another protection function. This system integrates protection logic with breaker control functions. The power required by the trip coil of the CB may range from 50 W for a small distribution CB to 3000 W for a large EHV CB. Where such appreciable current-carrying capacity is required, interposing contactor type elements will. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. Electrical values are measured by these relays to determine abnormal circumferences of a circuit.

Electromechanical protective relays operate by either, or. Unlike switching type electromechanical with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts.
