why the electric fuse are replaced by MCB
Answers
Answer:
Why use MCB instead of a Fuse? It detects any abnormality in the current flow and automatically switches off the electrical circuit. 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.
Explanation:
In comparison to a fuse, the MCB offers various advantages:
1. MCBs are more current-sensitive than Fuse.
Any anomaly in current flow is detected, and the electrical circuit is promptly turned off.
2. The malfunctioning zone of the electrical circuit may be easily recognized when using an MCB.
If a circuit is faulty, it will default to the Off position. In the event of a fuse, however, the entire fuse wire must be examined by opening the fuse grip in order to confirm the defective zone.
3. Resuming supply using MCB is a breeze.
All you have to do now is turn the MCB back on. However, if a fuse blows, the fuse wire must be replaced in its whole.
