CM3 series molded case circuit breakers are suitable for use in power distribution networks with rated operating voltage of 50HZ, 400V and rated current up to 800A. They are used to distribute electrical energy and protect circuits, power supplies and electrical appliances from overload, undervoltage and short-circuit hazards, thus improving the reliability of power supply. Under normal conditions, they can also be used for infrequent line shunting and infrequent motor starting.
