define electric fuse and MCB.
Answers
Answer:
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.
Answer:
In electronics and electrical engineering, 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.
Miniature Circuit Breaker or MCB A miniature circuit breaker or MCB is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.
