Product Over View:
1.Provide protection against earth fault/leakage current and function of isolation
2.High short-circuit current withstand capacity
3.Applicable to terminal and pin/fork type busbar connection
4. Equipped with finger protected connection terminals
5.Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
6.Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
