MHZM5L circuit breaker with residual current protection

MHZM5L series circuit breaker (CBR) with residual current protection is suitable for circuits with AC 50Hz/60Hz, rated operating voltage to AC415V, and rated operating current to 630A for power distribution protection, and can also be used for infrequent start-up of motors.

The circuit breaker has the protection functions of overload, short circuit and undervoltage, which can protect the circuit and power supply equipment from line failure. At the same time, it can also protect the long-term ground faults of the line that cannot be detected by the overcurrent protection device, and prevent the line from endangering personal safety and causing fire and other dangerous hazards.
