HOPE THIS HELPS UH
TY MARK AS BRAINLIES
Answer:
An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure.
Advantages
MCBs have more sensitive to current then fuse.
It has quick work against short circuits.
It works quickly on overloading and under voltage.
It is reusable hence less maintenance cost and less replacement cost.
It is very simple to resume the supply.
Ive made sure to give your answer as precise as possibly hope it helps
