RCCB NFIN

Detailed Product Description


NFIN Residual Current Device(RCCB) is mainly suitable for using in varieties of plants, enterprises, buildings, constructions, commerce, hotels and families. It can be used in circuits single phase 240V, three phases 415V, rated frequency 50 or 60Hz. 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. The Residual Current Device (RCD)NFIN is conformity with the standards of of IEC1008.1,GB16916.1.
