What is the difference between MCB & MCCB, Where it can be used?
§ MCB is miniature
circuit breaker which is thermal operated and use for short circuit protection
in small current rating circuit.
§ Normally it is used
where normal current is less than 100A.
§ MCCB moulded case
circuit breaker and is thermal operated for over load current and magnetic
operation for instant trip in short circuit condition. Under voltage and under
frequency may be inbuilt.
§ Normally it is used
where normal current is more than 100A.
