Tips: Difference between molded case circuit breaker (MCCB) and miniature circuit breaker (MCB)

1. Current grade: The current grade of the molded case circuit breaker can reach as high as 2000A while the maximum current of the miniature circuit breaker is within 125A. Because of the volume difference between the two types, in detailed application, the effective area of the molded case circuit breaker is also bigger than that of the mini circuit breaker. Meanwhile, the connected wire is also relatively thick and can reach 35 square. However, the miniature circuit breaker is only suitable to be connected with the wire below 10 square.
2. Installing means: The molded case circuit breaker is mainly installed by screws while the miniature circuit breaker is mainly installed through the guide rail.
3. Operation flexibility: The overcurrent and short-circuit protective equipment of the molded case circuit breaker are independent respectively. In the operation process, the operating value of the overcurrent protection still can be regulated flexibly. The overcurrent protection and the short-circuit protection of the miniature circuit breaker are the unified equipment. It has a certain deficiency in regulating flexibility. However, when it is required to improve the safety of the equipment because the movement of the micro circuit breaker has a high sensitivity and quick breaking action, it is beneficial for protecting the wire and apparatus.
