Question

Difference between fuse and mcb?

Answer 1

Answer:

If an overload occurs, the filament melts, stopping the flow of electricity. Fuse is a one time use device and melts when excess current passes through it and protects the other devices in the circuit. MCB or miniature circuit breaker is either electromagnets or a bi-metal strip.

Answer 2

Fuse:

a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.

MCB:

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
