Residual Current Circuit Breaker

Residual Current Circuit Breaker

• Provides protection against earth fault/leakage current and function of isolation

• High short-circuit current withstand capacity

• Applicable to terminal and pin/fork type busbar connection

• Contact position indication

• Equipped with finger protected connection terminals

• Fire resistant plastic parts endures abnormal heating and strong impact

• Automatically disconnect the circuit when earth fault/ leakage currento 

• When it occurs and exceeds the rated sensitivity.

• Independent of power supply and line voltage,and free from external interference, voltage fluctuation
