Application

ZMW50-1000 conventional circuit breaker (hereinafter call “breaker”) is suitably used in the distribution circuit of AC 50Hz, rated voltage 400V,  rated current 200 ~1000A, to distribute electric power and protect circuit and equipment from overloading, short circuit, under-voltage, single phase earthing, residual current faults. At normal working conditions the breaker can be used to transfer the distribution lines or start the motor non-frequently. The breaker provides the intelligent protection function and high precise selective protection, improve the reliability of power supply, and prevent unnecessarily cutting off power supply. The breaker has isolation function,

The breaker complies with the standards of GB14048.2 and IEC 60947-2 “Low-voltage switchgear and controlgear Part 2: Low-voltage circuit breakers”
