SONTUOEC NFIN 2P,4P Residual Current Circuit Breaker Device RCD Electronic /Magnetic type :
Application:
NFIN Residual current circuit breaker (without over-current protection)is suitable for the line of AC 50/60Hz,voltage 240V(2pole)/415V(4pole),rated currentup to 63A.When there is human electricity shock or if the leakage currenof the line exceeds the prescribed value, NFIN Residual current circuit breaker will cut off the power rapidly to infrequent chageover of the line in normal situation. NFIN Residual current circuit breaker is application to industrial area, commercial area, tall buikding and civil house.
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.
