What is MCCB
MCCB refers to a moulded case circuit breaker and is used when the load current exceeds the limits of a miniature circuit breaker.MCCB provides protection against overloads, short circuit faults and is also used for switching circuits. It can be used for higher current ratings and fault levels, even in domestic applications. the MCCB's wide current ratings and high breaking capacity are used in industrial applications. the MCCB can be used to protect capacitor banks, generator protection and major power feeder distribution.
What is MCB
An MCB is a miniature circuit breaker. It automatically closes the circuit in the event of any abnormalities in the grid, such as overload and short-circuit conditions. However, a fuse can sense these situations, but it must be replaced, although the MCB can be reset. an MCB is an electromechanical device that protects wires and electrical loads from overcurrent to avoid any kind of fire or electrical hazard. Handling an MCB is quite safe and it restores power quickly.
