NB-NFIN Residual Current Circuit Breaker

Short Description:

The Residual Current Device (RCD) NB-PFIM is in conformity with the standards of IEC 1008, 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. NB-PFIM RCD is manly suitable for using in varieties of plants, enterprises, buildings, constructions, commerce, hotels and families, it can be used in circuits up to single phase 230V, three-phase 400V, 50 or 60Hz.
