Abstract: A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.

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.
