Construction and Feature

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 current occurs and
exceeds the rated sensitivity.
Independent of power supply and line voltage, and free from external interference,voltage fluctuation.
