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

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.
