摘要:
An assembly for interacting with a circuit breaker operating mechanism of a circuit breaker, the assembly including an accessory device, an actuator, and a compliant device. The accessory device includes a plunger configured for movement between a retracted position and a protruded position. The actuator includes a first free end and a second free end, the second free end configured for mechanical cooperation with the plunger. The compliant device is disposed intermediate the operating mechanism and the actuator, the compliant device is configured for mechanical cooperation with the second free end of the actuator. A force is applied from the operating mechanism to the accessory device, the force for resetting the accessory device is transmitted from the operating mechanism to the compliant device, from the compliant device to the actuator, and from the actuator to the plunger for resetting the plunger from the protruded position to the retracted position.
