Fuse once break down, we have to replace it with another wire.

Please Explain with example.

In a electrical system when large current (i.e; fault occurs) flows, the fuse (use manually) will damage and doesn't have chance to use the same. But in a Circuit Breaker (works automatically), when fault occurs it will disconnect the system completely without damage and then we reuse the same CB.

Circuit breakers are have fast response than fuse and it is respond automatically so, it easily reusable.

Srikanth said: (Aug 10, 2012)  
Fuse gets burnt when any short or large current flows, so it cannot be reused (no question of reuse) , whereas CB just trips when a short occurs, so it can be reused by turning it to the initial position.

Hear fuse will be use in homes and circuit breakers will be use heavy lines. Once short circuit will be found fuse is burning and it is not working, but circuit breaker is automatically safe it self and it protect our project also.

What do you mean by tripping?

Pranjal Patil said: (Jul 5, 2013)  
Tripping means it automatically off the system.

Mani said: (Aug 14, 2013)  
Circuit breaker can be reset to normal by just tripping where fuse should be replaced.

What is the Circuit breaker? wire or component. Please give me reply.

A.Mohammed Imrankhan said: (Feb 16, 2014)  
Fuse: Fuse is a protecting device. When overloading is occur it will disconnect or break the conduction path (copper wire).

Circuit breaker: It acts as a switch when overloading is occur.

Fuse once burn replace another one but circuit breaker use so many times.

Gilbert Bernatsha said: (Feb 22, 2015)  
I think answer (A).

Fuse is one of the answer of that question.

Because fuse operated slowly compared with breaker.

Manoj said: (Dec 5, 2016)  
I think Answer D.

It is more reliable.

Jagdish Sahu said: (Jan 7, 2017)  
Circuit breaker is more reliable then fuse but it has many mechanical part which make it non reliable then fuse.

Mahesh said: (Jul 12, 2017)  
Which type of material used in the fuse and why?

Shadan said: (Jan 18, 2018)  
Fuses can be used only once.

But, Circuit breakers can be used a number of times.

Neeleshkumar Biradar said: (Sep 28, 2018)  
Circuit breaker is more reliable.

Explain it.
