ZGM21M Residual Current Circuit Breaker(RCCB):
1), Provides protection against earth fault/leakage current and function of isolation
2), High breaking current withstand capacity
3), Applicable to terminal and pin/fork type busbar connection
4), Equipped with finger protected connection terminals
5), Fire resistant plastic parts endures abnormal heating and strong impact
6), Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
7), Independent of power supply and line voltage, and free from external Interference, voltage fluctuation
