摘要:
A trip actuator reset assembly for a circuit breaker includes a cradle assembly, a reset lever, a trip actuator, and a resilient element. The cradle assembly is pivotably coupled to the circuit breaker pole shaft. The reset lever includes first and second ends, and a pivot pivotably coupling the reset lever to the circuit breaker housing. The resilient element is pivotably coupled to the housing proximate the second end of the reset lever. In response to a trip condition, an actuating element of the trip actuator moves the first end of the reset lever. To reset the trip actuator, a guide member guides the cradle assembly into engagement with the resilient element which pivots the reset lever. The first end of the reset lever then resets the trip actuator. After reset, if the cradle assembly continues to move, then the resilient element bends to accommodate the additional motion.
