Main difference between fuse
and C.B is that once over
heating current pass in fuse
the fuse breake the ckt bt C.B
breake the ckt and once
again it make ckt the current
start flow through ckt where
in fuse that is not possible
we have to change the fuse.

Answer / guest

fuse is the only it break the circuit when the overcurrent
flow in the circuit. But circuit breaker it will break and
make the circuit when circuit current is more and normal
current flowing in the circuit
