SONTUOEC NFIN 2P,4P Residual Current Circuit Breaker Device RCD Electronic /Magnetic type SKD SPARE PARTS :
Product Description:
SNFIN The residual current device (RCD) NFIN is in conformity with the standard of VDE 0664, CEE27 and BS 4293.
It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunk line. Thus it is suitable to avoid the shock hazard and fire caused by earth leakage. SG-NFIN ELCB is mainly suitable for varieties of plants and enterprises, buildings, construction, commerce, hotels and families. It can be used in circuits up to single-phase 240V; three phase 415V, 50 or 60 Hz.

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 sensitivity6.Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
