Abstract
A spring discharge mechanism for a circuit breaker is provided. The mechanism includes two linkages for crashing or discharging 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. The secondary mechanism includes a manual activation linkage that couples with an interface plate. The interface plate is coupled to an opening latch shaft and a closing latch shaft that cooperates to discharge the circuit breaker compression springs. An interface lever is also coupled to the interface plate. The interface lever includes a roller that interacts with a pivoting cam lever coupled to a drawout mechanism. The cam lever interacts with the roller causing the interface lever to rotate the interface plate, the opening latch shaft and the closing latch shaft.
