APPLICATION:
-
The
Residual Current Device(RCD) NFIN 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.NFIN RCD is mainly suitable for using in varieties of plants, enterprises,
buildings, constructions, commerce. Hotels and families, It can be used in
circuits up to single phase 240V,threephase 415V,50 or 60Hz.
