    Tips: Difference between molded case circuit breaker and miniature circuit breaker
    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 of the two types, in detailed application, the effective area of the molded case circuit breaker is also bigger than that of the miniature circuit breaker. Meanwhile, the connected wire is also relatively thick, which 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 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 operate value of the overcurrent protection still can be regulated flexibly. The overcurrent protection and the short-circuit protection of the miniature circuit breaker is the unified equipment. It has a certain deficiency in the regulating flexibility. However, when it is required to improve the safety of the equipment, because the movement of the miniature circuit breaker has a high sensitivity, quick breaking action, it is beneficial for protecting the wire and apparatus.

    Existing reviews of 25 amp 2 pole Miniature Circuit Breaker
    This MCB functions as described.
    I purchased this miniature circuit breaker to act as a cut and safety circuit breaker for my solar panel array. I am pretty confident this adds extra security to my system. This MCB functions as described. And I like it is DIN mounted.
