APPLICATION:
The items are mainly suitable for using in variety of plants,enterprises,buildings,
constructions,commerce,guesthouse and family within AC circuit
50/60Hz,voltage single-phase up to 240V,three-phase 415V.
It can cut off the fault circuit immediately on the occasion
of shock hazard or earth leakage of trunk line,thus,it can avoid
the shock hazard and fire caused by earth leakage. It is in
conformity with the standards of VDE 0664.CEE27 and BS4293. |
