This product complies with IEC******2, GB****8.2 

The MCCB, having rated insulation voltage **0V (Inm≤**0A) to **0V (Inm≥**0A) is designed to be used for distribution network of having rated current *0A to ***0A, rated operational voltage **0/**0V to **0/**0V, intended for power distribution, protection of electrical equipment and circuits against overload, short-circuit and under voltage, and also for unfrequent switching of electric circuits in most cases. MCCB with frame rating up to and including **0A can be used for unfrequent starting, and interruption of squirrel cage motors, and for protection of motors against overload, short-circuit and under voltage.

SS series circuit breakers can be equipped with electric accessories and mechanical accessories, such as under voltage release, shunt release, auxiliary contacts, alarm contacts, electric operating mechanism and rotary mechanical operating handle etc.

SS series intelligent moulded 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 beam indication of operation; 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 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.
