Abstract
A D/C trip assembly for a circuit breaker is provided. The D/C trip assembly includes a magnet, a mounting assembly and an armature assembly. The mounting assembly includes a body, the mounting assembly body including a pivotal coupling. The armature assembly includes a magnetic body and a trip bar linkage, the trip bar linkage extending from the armature assembly body. The armature assembly body is structured to move between a first position, wherein the armature assembly body is close to the magnet, and a second position, wherein the armature assembly body is spaced from the magnet. The trip bar linkage is structured to move between a first position and a second position, the trip bar linkage positions corresponding to the armature assembly body positions. The trip bar linkage is structured to be coupled to a trip bar.
