Abstract:
Spring operated actuator devices for an electrical circuit breaker and/or electrical switching device include at least one clock spring comprising a disc shaped body with gear teeth and a spiral spring, a cam shaft holding the at least one clock spring with an inner end portion of the spiral spring attached to the cam shaft, and a drive cam held by the cam shaft adapted to be in communication with a follower that directs an actuator to open or close a mobile contact to maintain open and closed energy status of the electrical circuit. The at least one clock spring is configured as a closing spring of the spring operated actuator.
