Write the difference between MCB and FUSE ?
Answers
The MCB and a normal fuse have the same function. Both, are used to prevent the circuit from an excess flow of current resulted due to short circuit or overload. When the current flow exceeds a fuse wire burns out in order to open the circuit. Where an MCB disconnects the circuits by tripping
.MCB is an electromagnetic device. It works by moving a switch mechanism with an electromagnetic force developed from a solenoid.
.MCB’s are sensitive than the fuse.
.MCB’s are easy to restart after the tripping as it has no any replacing parts. Just a switching like a normal switch can reset the circuit. It is feasible for the common users and the circuit can be closed within no time.
.MCB’s gives safe protection because it has a perfect package with an enclosed case. So it can ensure complete isolation.
.MCB’s are long lasting.

steap by step
Explanation:
Both MCB and Fuse are circuit breakers or protecting devices.
Fuse : Fuse is an electrical device that has a conductor with low resistance,when the current load is very high that melts the conductor due to heat generated and circuit opens thereby saving other devices in the same circuit from short circuit.
Less Sensitive than MCB.
Fuses can be used only once.
It does not give any indication.
Fuse cannot be used as an ON/OFF switch.
Completely automatically
MCB : Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. The lead reasons for an overcurrent could be a short circuit or overload. Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused
MCB’s are sensitive than the fuse and are long lasting
MCB’s are easy to restart after the tripping as it has no any replacing parts.
It gives an indication of the status
The Circuit breaker is used as an ON/OFF switches.
Manually as well as automatically operated.
