Miniature circuit breakers

The miniature circuit breaker is a basic protective device for preventing short circuits and overloads. The tripping characteristics, rated load capacity, and breaking capacity of the miniature circuit breakers must be taken into account, which are clearly shown by the markings on them. Tripping characteristic curves: “B” is fast, which is generally used to protect sockets and lighting circuits: “C” is slower, usually used for devices with higher current consumption, “D” is slow, this type of miniature circuit breaker is mainly used in industrial buildings. The most common miniature circuit breaker ratings are 2-63 Amperes, B10A, B16A, C16A. Miniature circuit breakers are also distinguished by the number of poles, they can be: 1, 2, 3, 4 poles.
