摘要: A trip unit includes a housing, rotary plunger mounted in the housing and pivotal bar also therein. The latches an on position, releases to tripped position re-latches plunger. set of springs biases position. lever is pivotally housing. solenoid linear plunger, which resets when retracted, engages rotates extended, order rotate release reset same opposite direction, retract solenoid. During that operation, cams bar, re-latch
