20220384134 · 2022-12-01 ·

A trip device is disclosed. The trip device according to an embodiment of the present disclosure comprises an adjustment crossbar. The adjustment crossbar is in contact with or is spaced apart from a shooter and can open or close a breaker having the trip device. The adjustment crossbar is formed by coupling a fixed crossbar and a movable crossbar. The movable crossbar is slidably coupled to the fixed crossbar. The shooter is in contact with the fixed crossbar. Therefore, regardless of the movement of the movable crossbar, the contact between the shooter and the fixed crossbar can be maintained.
