Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker track buckle structure. Background Art

[0002] A circuit breaker (also known as a circuit breaker) is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, as well as closing, carrying, and interrupting current under abnormal circuit conditions (including short-circuit conditions) within a specified timeframe. Circuit breakers are used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. They automatically disconnect circuits in the event of severe overloads, short circuits, undervoltages, and other faults. Their functionality is equivalent to a combination of a fuse-type switch and an over- and under-temperature relay. Furthermore, interrupting fault current generally requires no component changes. Currently, circuit breakers are widely used.

[0003] Currently, all miniature circuit breakers (MCBs) on the market are installed using track clips, generally with a two-stage clip structure. Therefore, the circuit breaker can only be installed on two sizes of tracks, resulting in low applicability. During installation, the clips need to be pulled open, and after installation, they need to be reset manually without the use of tools. This operation is laborious, affecting operational efficiency and the human-computer interaction experience. Utility Model Content
