âMCBâ stands for âMiniature Circuit Breakersâ while âMCCBâ is âMolded Case Circuit Breaker.â. The main difference between the two is their capacity with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps.ircuit breakers are usually reset after they have been âtripped.â Both MCB and MCCB are highly durable and could last for years depending on the manufacturer. When choosing between using an MCB and an MCCB, it is important to consider the amount of power that would be coursing through the device.
