Claims

[Claims for Utility Model Registration] An operating handle manually operated from the outside, a link whose one end is connected to the operating handle and whose other end is removably engaged with a push plate, and a link between the link and the push plate. a lever that receives a component of the force generated in the engagement portion and transmits the force to the automatic tripping device and is pivotally connected to the frame to maintain the engagement; and a lever that is rotatably supported by the first frame shaft and that a latch that is always biased to a position where it engages with the lever by a spring; a movable contact that is rotatably supported by a second frame shaft and inserted and held through a hole in the push plate; an equipment protection circuit breaker having a contact pressure spring provided on a child and urging the push plate in the direction of the link; An R link that rotates, an AL link that is rotatably supported by the second frame shaft with a long hole and whose one end is rotatably connected to one end pin of the R link, and a micro switch that is attached to the case. , and a second spring biasing the R link and the AL link in the non-operating direction of the microswitch, the latch being rotated against the first spring by the automatic tripping device when tripped. When the lever is released, the link operated by pushing the lever rotates the R link against the second spring, and the rotation of the R link causes the micro A circuit breaker for equipment protection, characterized in that a switch is activated.
