To provide a spring release mechanism for a circuit breaker that releases the energy from the compression springs of the circuit breaker prior to being removed from service.
The spring release mechanism includes two linkages for crashing or releasing the circuit breaker compression springs to allow the circuit breaker to be used in either fixed breaker installation or in an installation having a drawout mechanism 52. The secondary mechanism includes a manual activation linkage 56 that couples with an interface plate 68. The interface plate 68 is coupled to an opening latch shaft 69 and a closing latch shaft 71 that cooperates to release the circuit breaker compression springs. An interface lever 80 is also coupled to the interface plate 68. The interface lever 80 includes a roller 96 that interacts with a pivoting cam lever 98 coupled to the drawout mechanism 52. The cam lever 98 interacts with the roller 96 causing the interface lever 80 to rotate the interface plate 68, the opening latch shaft 69 and the closing latch shaft 71.
