Low Voltage 3 Pole Circuit Breaker Manufacture
Product Information
MM1 series moulded case circuit breaker is a new type product developed and manufactured by Adopting international advanced technology. It is supplied with rated insulation voltage 1200V and used for circuit of DC 50Hz/60Hz, rated operation voltage DC 1200V or below rated operation current up to 1600A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current ,short circuit and under voltage,the product is capable of preventing damage of circuits and supply units.
The mccb can be sorted to C type (basic),L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.
The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship.
