Abstract

A small-size prepayment circuit breaker comprises a casing, a circuit breaking part and a prepayment part, wherein the casing comprises an intermediate casing; the circuit breaking part comprises an operating mechanism, an arc extinguish chamber and two gold pieces; each gold piece comprises a fixed end and a movable end; the prepayment part comprises a prepayment circuit board; the prepayment circuit board and the two gold pieces are respectively positioned on two sides of the intermediate casing; the prepayment circuit board is communicated to the two gold pieces through a signal transmission line; and a through hole through which the signal transmission line penetrates is formed in the intermediate casing. According to the small-size prepayment circuit breaker disclosed by the invention, the prepayment part is communicated with a breaking part without influencing a movable contact; and the circuit breaker is stable in performance.

Description

technical field [0001] The invention relates to a miniature circuit breaker, in particular to a prepaid miniature circuit breaker. Background technique [0002] A circuit breaker is an electrical appliance that not only has a manual switch function, but also can automatically perform overload and short-circuit protection. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse switch and A combination of overheating and underheating relays, etc. Moreover, it is generally not necessary to change parts after breaking the fault current, and has been widely used. Due to the needs of the industry, someone has designed a prepaid miniature circuit breaker, that is, a prepaid part is added to the miniature circuit breaker, including a prepaid circuit board. By in...
