Answer 2

Answer:

The full form of MCB is Miniature Circuit Breaker . ... It can detect a problem occurring inside a circuit by identifying the extreme amount of current flow in the circles. If there is a large amount of power available in the loop, it can break the loop any moment. The fuses are often used as a substitute for the MCBs.
