ABSTRACT:
A trip actuator reset assembly for a circuit breaker includes a cradle assembly, a reset lever, a trip actuator, and a rigid element. The cradle assembly is pivotably coupled to the circuit breaker pole shaft, and includes a number of springs. A pivot pivotably couples the reset lever to the circuit breaker housing. In response to a trip condition, an actuating element of the trip actuator moves a first end of the reset lever. The rigid element is pivotably coupled to the housing proximate a second end of the reset lever. To reset the trip actuator, a guide member guides the cradle assembly into engagement with the rigid 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 springs accommodate the additional motion.
