Difference between Circuit Breaker and Fuse

Circuit breaker:
Has switching actions to close the circuit or to open the circuit, and
has a trip circuit if load current exceeds the set value.
After tripping, circuit breaker can be reused without replacing any part.

Fuses:
Have only breaking function, and fitted in the circuit to protect the circuit from damaging effect of high current flow.
It breaks the circuit by melting the fuse metal itself.
After breaking, the blown fuse must be renewed.
