2,Isolation and earth leakage
N7-II PFIM Residual Current Device/RCD :
1,Provides protection against earth fault/leakage current and function of isolation High breaking current withstand capacity.
2,Applicable to terminal and pin/fork type busbar connection.
3,Equipped with finger protected connection terminals.
4,Fire resistant plastic parts endures abnormal heating and strong impact.
5,Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
