Abstract: A lever member is for a trip assembly of an electrical switching apparatus. The electrical switching apparatus includes a housing, a signaling mechanism, separable contacts, and an operating mechanism structured to open and close the separable contacts. The trip assembly includes a mounting assembly disposed on the housing and a drive assembly. The drive assembly includes an actuator coupled to the mounting assembly and a plunger disposed on the mounting assembly and being cooperable with the operating mechanism. The lever member includes: a pivot portion structured to engage the mounting assembly; a first arm portion structured to engage the plunger; and a second arm portion disposed between the pivot portion and the first arm portion, the second arm portion being structured to engage the actuator.

Abstract: A trip unit wherein one sidewall of a trip unit housing assembly captivates a trip bar is provided. A captivation assembly is coupled, or directly coupled, to a trip unit housing assembly, thereby limiting tolerance buildup. The captivation assembly includes a trip bar bearing cap having a stop feature, thereby limiting tolerance buildup. The trip bar includes a radial stop paddle having hemispherical protrusions structured to contact the trip unit housing, thereby limiting tolerance buildup. The captivation assembly elements are incorporated into the trip unit housing assembly and captivates the trip bar in all but one axis, thereby limiting tolerance buildup and improving repeatability.
