NC100H(DZ47-100) Miniature circuit breaker MCB

NC100H(DZ47-100) Miniature circuit breaker MCB 6000A 8000A high breaking capacity Conformity with GB10963,IEC60898 standards

NC100H(DZ47-100) Miniature circuit breaker MCB 

NC-100H mini circuit breaker is mainly suitable for overload and short protection. It is especially used for illumination and distribution. It is of pleasing out-look, light weight, reliable performance, high breaking capacity, quick trip. etc. Its frame and parts adopt plastic of high inflammable resistance and shock resistance for long service life. It is mainly used for overload and short circuit protection within the circuit of AC 50/60Hz, rated voltage of single pole up to 230V, two, three of four poles up to 400V. It can also be used for an unfrequent switchover of circuit and illumination under normal conditions.
