Application
SM8 series Molded case circuit breaker(hereinafter referred to as MCCB) is the new series MCCB, which is developed strictly according to
international standards and manufactured with advanced technology.
This product complies with IEC60947-2.The MCCB, having rated insulation voltage 500V(lnm ≤ 160A) to(lnm ≥ 250A) is designed to be used for distribution network of having rated current 10A to 1600A, rated operational voltage 380/400V to660/690, intended for power distribution, protection of electricalequipments and circuits against overload, short-circuit and undervoltage, and also for unfrequent switching of electric circuits in mostcases. MCCB with frame rating up to and including 400A can be used for unfrequent starting, and interruption of squirrel cage motors, and for protection of motors against overload, short-circuit and under voltage.
SM8 series circuit breakers can be equipped with electric accessories and mechanical accessories, such as under voltage release, shunt release, auxiliary contacts, alarm contact, electric operating mechanism and rotary mechanical operating handle etc.
SM8 series intelligent molded case circuit breakers are equipped with electronic release with the function of protection of electric circuits and equipments not only against overload, short-circuit and under voltage, but also against earthing failure. The intelligent functions of it are: current failure; output of over-current signal and monitoring of circuit breaker 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.
