Earth leakage protection switch type FIN 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. It is mainly suitable for use in variety of plants and enterprises , building , construction, commerce, guesthouses and families. It can be used in circuits up to single phase 240V, three phase 415V, with AC50 to 60Hz. It is in conformity with the standards of VDE 0664, and BS 4293.
