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; a contact pressure spring provided on the child and biasing the push plate in the link direction;
A monopole having a trip bar link rotatably supported on a frame axis and rotated by the other end of the link during tripping, and a second spring biasing the trip bar link to a non-trip position. The circuit breaker is made up of multiple poles by overlapping the cases, and the trip bar link of each pole is integrally interlocked by being inserted through a hole in the case of each pole and spanning over each pole. a trip bar connected to the lever, wherein the one-pole automatic tripping device rotates the latch against the first spring to release the lever, and the link operated by pushing the lever releases the trip bar. When the bar link is rotated against the second spring, the trip bar link of the other pole and the trip bar rotate due to the rotation of the trip bar link. A circuit breaker for protecting equipment, characterized in that the latch is rotated against the first spring so that all poles trip simultaneously.
