Claims

[Claims for Utility Model Registration] (1) 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 a mechanism frame supported by this mechanism frame. The multi-pole circuit breaker has a trip bar whose end extends to an adjacent pole without an opening/closing operation mechanism of the breaker case, and an automatic tripping device for tripping the trip bar, wherein the opening/closing operation mechanism is provided. and 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 stop the cradle from being rotated by the cradle, and the automatic tripping lever is provided with 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 stop the cradle from being rotated by the cradle. When the trip bar is rotated by a trip member of the device, 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, flips up, and trips, The trip bar is divided into a trip bar body and a latch part, and the latch part is connected to the locking gun, the latch lever,
A multi-pole circuit disconnector characterized in that, after the trip relay mechanism is assembled in a trip relay mechanism consisting of a trip bar or the like and attached to the disconnector case, the trip bar main body can be assembled to the latch part. (2) The multi-pole circuit breaker according to claim 1, wherein the trip bar body is a molded resin product, the latch part is a metal press product, and both are assembled with mounting screws.
