Summary:The present invention provides an anti-pumping system for a circuit breaker. In an anti-pumping system for a circuit breaker which includes a relay for transmitting an inputting and blocking signal to the driving part of the circuit breaker and preventing a pumping operation that the inputting and blocking of the circuit breaker are repeated after the input of the circuit breaker, and receives a DC power source. The relay is configured as an AC relay and comprises an external resistor connected to contact b provided in the AC relay. So, the anti-pumping system can satisfy fast loading speed. 본 발명은 차단기의 구동부에 투입 및 차단 신호를 전달하되 차단기의 투입 후에 차단기의 투입 및 차단이 반복되는 펌핑동작을 방지하는 릴레이를 포함하고, DC 전원을 공급받는 차단기의 안티펌핑 시스템에 있어서, 상기 릴레이는 AC릴레이로 구성되고, 상기 AC릴레이에 구비되는 b 접점에 연결되는 외부저항을 포함하는 차단기의 안티펌핑 시스템을 제공한다.
