Application Range

FCM7L(DPN)**2 series miniature circuit breaker is used for single phase circuits with AC *0 and rated voltage up to **0V AC. It’s applied to protect earth leakage, overload and short circuit of electric circuit. It complies with IEC******1, GB****7.7 standards.

Structure Feature

FCM7L(DPN)**2 series earth leakage circuit breaker extends from FCM***2, its advantages: high breaking capacity, small size, compact structure, two poles (P + N) with *6mm width of four moulds, cutting off phase line and N line at the same time. And N pole has feature of first switching on then breaking. It can still make protection for earth leakage when phase line and N line is incorrect connected.
Visible indicators for earth leakage is fitted, white means no earth leakage, red means earth leakage. Adopt conductor connection, up to *0mm2 round copper conductor is allowed.
Test device with rest push button is arranged for the breaker, and analogue residual current will be produced in inner circuit to switch off circuit breaker when push the button. Monthly test shall be required for test facility.
