Claims

[Claims for Utility Model Registration] A breaker case having multiple poles, a mechanism frame installed on a mechanism pole with an opening/closing operation mechanism of the breaker case, and an end portion supported by the mechanism frame. is a multi-pole circuit breaker having a trip bar extending to an adjacent pole without an opening/closing mechanism of the breaker case, and an automatic tripping device for tripping the trip bar, wherein the cradle of the opening/closing mechanism and the cradle of the opening/closing mechanism; A latch lever that engages with the cradle to position the cradle; and a latch lever that engages with the cradle and the trip bar to prevent the cradle from being rotated by the cradle; When the trip bar is rotated by the member, the latch lever is disengaged from the trip bar and released together with the locking mechanism, so that the cradle rotates the released locking mechanism and the latch lever, causing them to spring up and trip; It is divided into a main body and a latch part, and the latch part is assembled into a trip relay mechanism consisting of the locking gun, the latch lever, the trip bar, etc., and the trip relay mechanism is attached to the disconnector case, and then the trip bar main body is attached to the latch part. In the device that can be assembled, the trip bar body is made of a molded resin product, the latch part is made of a pressed metal product, and a metal piece is inserted into a part of the trip bar body where the latch part is attached, and the metal piece is and the latch portion are assembled using mounting screws.
