Deciding where to put your drives requires more than just casual consideration. If your VFDs are failing prematurely, it may be because they're located in your motor control centers (MCCs). MCCs optimize space by putting motor controls and branch-circuit protection in a common enclosure.
MCB is a miniature circuit breaker which is used to break small currents. Like in domestic LT circuits. The ratings usually end up to 100 A. MCCB is a Module case circuit breaker which has a rugged construction as it can break larger currents usually from (100-1000A). MCB and MCCB are usually used in LT/LV circuits. The breaker mechanism is more or less similar in both of these either magnetic or thermo-magnetic.
