A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.
MCCBs are built in a manner to handle high currents and are used widely in heavy-duty applications, such as adjustable trip settings for applications with low currents, protecting capacitor banks, welding machines, protecting motors, protecting generators and electric feeders.
