MCB is miniature circuit breaker which is thermal operated and use forshort circuit protection in small current rating circuit in branches of panel boards for small loads.MCCB moulded case circuitbreaker and is thermal operated for over load current and magnetic operation forinstant trip in short circuit condition.he main differences are The MCCB is equipped with tripping coil and can give a signal. The protection board of MCCB is more developed. It has L-L, L-G, thermal, and instantaneous setting, while MCB doesn't has those facilities. MCCB is usually used for high current application/.
