1 Answer

Answer :

A: MCB is miniature circuit breaker which is thermal operated for overload condition and magnetically operated  for short circuit protection. It is available in small current rating. MCCB is moulded case circuit breaker which is thermal operated for overload condition and magnetically operated  for short circuit protection.Under voltage and under frequency may be inbuilt. Normally it is used where normal current is more than 100 A.
