Description
Molded Case Circuit Breaker
Rated insulation voltage this series up to 1000V, suitable for power distribution network with AC 50Hz, rated voltage 400V (690V), rated current to 800A, used for distribution of electrical energy and protection the circuit and power equipment from overload, short circuit, under-voltage, and other faults. At the same time, it can also be used as the infrequent start and overload, short circuit, under-voltage protection of the motor.
The circuit breaker has the characteristics of small size, high breaking capability, and short flying arc. The circuit breaker can be installed vertically or horizontally.
This product conforms to IEC60947-2, GB/T14048.2, and other standards.
