Residual Current circuit breakers [Sep 11,2016]
Residual Current circuit breakers
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.
