Answer / vaseekaran
MCCB is used where the system voltage is up to 600v ac.motorized MCCB's are used more that 630A rating.In normal (manually) operated MCCB's we have to charge the spring manually every time when it changes to off state.in motorized MCCB's it will automatically charged the spring with the help of spring motor and ready for the next operation.these motorized breakers are very usefull in the auto change over system.
