<p>A trip unit (40) wherein one sidewall of a trip unit housing assembly (100) captivates a trip bar (48) is provided. A captivation assembly (120) is coupled, or directly coupled, to a trip unit house assembly (100), thereby limiting tolerance buildup. The captivation assembly (120) includes a trip bar bearing cap (126) having a stop feature, thereby limiting tolerance buildup. The trip bar (48) includes a radial stop paddle (66) having hemispherical protrusions (69) structured to contact the trip unit housing (100), thereby limiting tolerance buildup. The captivation assembly (120) elements are incorporated into the trip unit housing assembly (100) and captivates the trip bar (48) in all but one axis, thereby limiting tolerance buildup and improving repeatability.</p> |
