NFIN RCCB Residual Current Circuit Breaker

NFIN series Residual Current Circuit Breaker

provide the function of isolation switching and earth leakage protection of electrical circuits.And also provide the indirect protection of the operator's body against the dangerous effects of electric current and provide the protection of the fire caused by the electrical circuit fault. NFIN RCCB is designed according to international famous company on the base of IEC61008-1 Standards. Which with the features as follows:

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

2.High short-circuit current withstand capacity

3.Contact position indication

4.Applicable to terminal and pin/fork type busbar connection

5.Equipped with finger protected connection terminals

6.Fire resistant plastic parts endures abnormal heating and strong impact

7.Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity

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