RCCB NFIN 2P/4P 16A,25A,40A 63A 100A MAGNETIC RESIDUAL CURRENT CIRCUIT BREAKER RCD:
Application:
NFIN series Residual Current Circuit Breaker without over current protection conforms to the standards of GB16916.1, IEC1008, BS4293 etc. It is used in the circuits of AC 50~60Hz, single phase 230V(220V), three phases 400V (380V) in industrial & mining enterprises, commercial buildings and housing for protection of personal electric shock hazard and electric equipment and for unfrequent switchover of circuits under normal conditions.
NFIN Residual current circuit breaker complies with standard IEC/EN61008.1 and GB16916
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.
