SG-NFINSERIRS Residual Current Circuit Breaker RCCB/RCB/ELCB

1)Number Of Pole: 1P+N , 3P+N 2)Rated Current: 16,20,25,40,50,63 AMP (30,100,300,500M)

         SG-NFIN  The residual current device (RCD) KFIN is in conformity with the standard of 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. SG-NFIN ELCB is mainly suitable for varieties of plants and enterprises, buildings, construction, commerce, hotels and families. It can be used in circuits up to single-phase 240V; three phase 415V, 50 or 60 Hz.
