The Residual Current Device(RCD) NFIN is in conformity with the standards of IEC61008, VDE 0664, CEE27 and BS4293.
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, guesthouses and families. It can be used in circuits up to single phase 240V,threephase 415V,50 or 60Hz. |
