Residual Current Circuit Breaker
(RCCB/RCD)
RNR3-63

Collection
Application
RCCB RNR3-63 was designed as per IEC/EN 61008-1.It meets the demand of earth fault,residual current protection.It is applicable to industrial site,commercial site,tall building and residential site.
Features
·Provides protection against earth fault/leakage current and function of isolation.
·High short-current withstand capacity
·Applicable to terminal and pin/fork type busbar connection
·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
