M2 series Mouded case circuit breaker is one of new type breakers which this company adopts international advanced design, manufacture technology to develop, The rated insulating voltage is 950V, Suitable for AC 50Hz(60Hz), rated working voltage 69V or below, rated working current is 12.5 to 630A of circuit. and use in distrbuting electric energy. Non-frequent making and breaking in the normal conditions and protecting when circuit and installation are overload, short circuit and lacking voltage. Rated shell-rack and the breaker which current is under 400A.take protect effect when mousecage motor's non-frequent start,breaking off working and protecting overload, short circuit and lacking voltage.
