On the other hand, the MCCB is more suited in providing energy for high-power equipment. Judging from their power capacities, the MCB is mainly used for low-energy requirements, like home wiring or small electronic circuits. Their interrupting rating ranges from around 10,000 amps to 200,000 amps. Usually, this type of circuit breaker would provide amps as high as 2,500 or as low as 10, depending on what is necessary. On the other hand, an MCCB comes with an adjustable trip characteristic for the higher models. Consequently, their trip characteristics may not be adjusted since they basically cater to low circuits. “MCB” stands for “Miniature Circuit Breakers”, while “MCCB” is “Molded Case Circuit Breaker.” 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. However, before we talk about the key features of each, it is important to understand what the abbreviations stand for. Although both are circuit breakers, there are actually key differences between the two that make them specially made for specific jobs.
