摘要：
A circuit breaker includes separable contacts, an operating mechanism structured to open and close the separable contacts, and a magnetic trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The magnetic trip mechanism includes a support structure including a slotted support portion therein, and a plunger assembly. The plunger assembly includes a movable core resting in the support portion of the support structure, and a plunger member including a first portion cooperating with the operating mechanism, a second portion coupled to the movable core, and a third portion engaging the support structure.
