Product Description

1. Application
The Miniature Circuit Breakers are mainly used in AC 50Hz/60Hz circuit with rated voltage 230V, rated current up to 40A , and rated operating breaking capacity no more than 6000A power distribution system, protection of control circuit against short circuit and overload current fault. And also have circuit control and isolation function. The miniature Circuit Breakers is same as single pole miniature circuit breaker, the difference is the MCB can cut off phase and neuter wires at same time when current faults happen.
