MCB and MCCB are both circuit breakers, but differ in their current rating and trip characteristics.

MCB stands for Miniature Circuit Breaker and is used for low current applications up to 125A.
MCCB stands for Molded Case Circuit Breaker and is used for higher current applications up to 2500A.
MCBs have a fixed trip current rating and are designed to trip quickly in case of overload or short circuit.
MCCBs have adjustable trip settings and can be customized for specific applications.
MCCBs are more expensive than MCBs due to their higher current rating and additional features.
