“A Miniature Circuit Breaker is an electromechanical device designed to protect an electric circuit from over-current – A term to describe an electrical fault caused by either overload or short circuit. … MCBs improve on this functionality as they are usually not destroyed during over-current so are reusable.The primary function of a miniature circuit-breaker is to protect an installation or appliance against sustained overloading and short-circuit faults, but it will also give protection against earth faults provided that the earth fault loop impedance is low enough.
1. MCB is more sensitive to current than Fuse
It detects any abnormality in the current flow and automatically switches off the electrical circuit.
2. In case of MCB, the faulty zone of electrical circuit can be easily identified
Faulty circuit trips to the Off position. On the other hand, in case of a Fuse, the complete fuse wire needs to be checked by opening the fuse grip for confirming the faulty zone.
3. With MCB, it is very simple to resume the supply
You just need to push the knob of MCB back to the On position. But in case of a fuse, the entire fuse wire needs to be replaced.
4. Handling MCB is electrically safer than handling a Fuse. In case of MCB
In case of an MCB, the user is not exposed to live electrical parts; but while replacing the Fuse, there is a fair chance that you may come in contact with a live wire / current carrying conductor.
5. MCB is reusable and hence has less maintenance and replacement cost”
