Moulded Case Circuit Breakers are used to protect damage of equipment in case of excess current flowing through the circuit. The Breakers are used in heavy duty application where higher breaking capacity is required such as 16KA, 35KA etc. The Breakers are used for tripping the circuit when leakage current starts flowing or in case of earth fault. The Moulded Case Circuit Breakers are used in rooms where people are working, to avoid getting shocked.
