Product Description

DZ20 molded case circuit breaker(MCCB) is designed for electricity circuit with rated frequency of 50/60Hz, rated voltage of 380V(400V) and rated working current of up to 1250A to protect the circuit from damage caused by overload or short circuit. Usually this kind of MCCB is used for power distribution. It also can be used for protecting electric motors.

DZ20 MCCB for distribution is usually installed in power distributing grid for dispatching electricity, meanwhile for protecting circuit and devices against overload and short-circuit. DZ20 MCCB for motor protection is used for normal current breaking in cage type motor’s start-up and operation, at the same time, for protection against overload and short circuit.
