NFIN Residual Current
Device |
| 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,
three phase 415V, 50 or 60Hz. |
