摘要： A plug-in circuit breaker that includes a circuit breaker housing with a limiting hole and a opening and closing button. The circuit breaker further includes a locking member rotatably arranged inside the circuit breaker housing with an upper portion close to the limiting hole provided with a locking protrusion fitting. A lower portion of the circuit breaker housing is provided with a locking driving surface fitting with the opening and closing button. When the limiting hole is not shielded, the opening and closing button jacks up the locking driving surface to enable the locking protrusion to extend out of the limiting hole. The plug-in circuit breaker is closed when the limiting hole is shielded, so that the locking protrusion cannot extend out of the limiting hole. The locking driving surface limits the opening and closing button, so that the opening and closing button cannot press to the destined position.
