Best answer

1. MCB means Miniature Circuit Breaker. 

2. It is being used in place of electric fuses. 

3. There is a switch which automatically turns off when electricity in circuit exceeds the safe limit. 

4. So, the circuit is opened. 

5. We just need to switch ON to resume electric supply. 

6. At present MCB is available with automatically resumed built-in mechanism. 

7. MCB is better than electric fuses. 

8. There is no need to change it often. 

9. But fuse wire has to be changed whenever it melts. 

10. Hence, I appreciate the MCB for protecting home appliances.
