What is the full form of MCB

MCB: Miniature Circuit Breaker

MCB stands for Miniature Circuit Breaker. It is automatically operated electronics switch used to protect an electrical circuit from damage caused by overload or short circuit.

It is designed to detect the fault in the electrical circuit by detecting the extreme amount of current flow in the circuit and breaks the circuit as soon as possible.

Initially, fuses were used in place of MCB. Fuses require being substitute after a short circuit at the same time MCB just has to be reset and it will start working. MCB provides better operational safety and is suitable to use.

Features of MCB

Managing MCB is much secured than a fuse for electrical appliances as well as human beings.
In MCB, defective wire trips off from an original place which makes it very much achievable without enormous effort to detect faults.
It offers an enhanced interface by using a knob.
MCB is reusable and cheaper than a fuse.
It is more sensitive to current.
To return supply, a person just has to push the knob.
