DSM2 series Moulded Case Circuit Breaker (hereinafter referred to as MCCB) is the new series MCCB, which is developed strictly comply with international standards and manufactured with advanced technology by Dision Electric Co., Ltd. This product complies with IEC60947-2,GB14048.2.
The MCCB, having rated insulation voltage of 500V(Inm≤160A) to (Inm≥250A) is designed to be used for distribution network of having rated current from 10A to 1600A, rated operational voltage from 380/400V to 660/690V, intended for power distribution, protection of electrical equipment and circuits against overload, short-circuit and under voltage, and also for unfrequent starting, and interruption of squirrel cage motors , and for protection of motors against overload, short-circuit and under voltage.
DSM2 series Circuit Breaker can be equipped with electric accessories and mechanical accessories, such as under voltage release, shunt release, auxiliary contacts, alarm contacts, electrical operating mechanism and rotary mechanical operating handle etc.
DSM2 series intelligent moulded case circuit breakers are equipped with electronic release with the function of protecting electric circuits and equipment, which can not only against overload, short-circuit and under voltage, but could also against earthing failure. The intelligent functions include as below: indication of operation current beam, indication of power source and self-diagnostic, indication of pre-alarm and alarm for over-current failure, output of over-current signal and monitoring of circuit breaker's open/close. Particularly, the intelligent trip unit is designed with interface available for remote measuring , remote adjusting, remote controlling and remote communicating between circuit breakers and computers.
