This article describes the anti-pumping relay, its definition, function, and circuit diagram. In a circuit breaker it is desired that when close and trip operation is performed on the circuit breaker with the closing coil energized, the subsequent closing operation should be prevented. So let's. Anti-Pumping relay is nothing but a NO contact, which means when the circuit breaker in closed condition the relay will be as NO point and if the circuit breaker in open condition the relay will be as NC Condition. The anti-pumping relays is connected in series with the circuit. An anti pumping relay (also called antipumping relay or Y-relay and ANSI 94 Trip or Trip-Free Relay) is a protective device that prevents a circuit breaker from closing repeatedly when a continuous close command is present. In simple terms, it stops your circuit breaker from “pumping” – which means. Anti-pumping relays are used in circuit breakers to prevent the breaker from closing unexpectedly after tripping. If the TNC switch fails (Trip normal close) or there is any problem with the CB (circuit breakers) closing circuit, the continuous CB (circuit breakers) close command can be extended to. Why is the Anti-Pumping Relay Used? A circuit breaker is a very important equipment for a high-voltage power system. It protects the system from high current or voltage during a faulty condition.
