Application Range
FCM7(DPN)-32 series miniature circuit breaker is used for single phase circuits with AC 50/60Hz and rated voltage up to 230V AC. It’s applied to protect overload and short circuit of electric circuit, and also widely used as branch switch for family, hotel, apartment, hospital and industrial enterprise. The ideal product for residential field as protection switches for power distribution.
Structure Feature
FCM7(DPN)-32 series miniature circuit breaker has some advantages like: high breaking capacity, small size, compact structure, two poles (P + N) with 18mm width of two moulds, cutting off phase line and N line at the same time. And N pole has feature of first switching on then breaking that can avoid prison risk caused by incorrect connection of phase line and N line or voltage to ground of N line.
