Detailed Product Description

 Residual current circuit breaker (RCCB)

CONTRUCTION AND FEATURE

1) Provides 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) Fire resistant plastic parts endure abnormal heating and strong impact

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
