Answer 1

Hey mate!!!

MCB- Miniature Circuit Breaker.

The main function of MCB is to break the circuit when a higher current voltage is flowing through the conductor.

Even Fuse can handle this abnormal conditions(Fault, short circuit, etc).

But mcb is flexible in operation is possible, whenever circuit is tripped just we need to change position of MCB as like as our switch.

Hope you are satisfied with my ans
