What is a MCB?
A MCB (Miniature circuit breaker) is a mechanical switching device which is capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and automatically breaking currents under specified abnormal circuit conditions such as those of short circuit. In short, MCB is a device for overload and short circuit protection. They are used in residential & commercial areas. Just like we spend time to make a thorough check before buying appliances like washing machines or refrigerators, we must also research about MCBs. Also, if you are still using a fuse then you must replace it with MCB.
Need of MCB?
Electrical distribution needs are continuously evolving in residential, commercial and Industrial sectors. Improved operational safety, continuity of service, greater convenience and operating cost has assumed a tremendous significance. Miniature circuit breakers have been designed to continuously adapt to these changing needs.
