Abstract
A close latch interlock assembly is provided for an electrical switching apparatus, such as a circuit breaker, which includes a stored energy mechanism, such as a closing spring. The close latch interlock assembly includes a close D-shaft pivotable between a latched and unlatched positions corresponding to the closing spring being chargeable and discharged, respectively. An actuator is movable between an unactuated position corresponding to the close D-shaft being disposed in the latched position, and an actuated position corresponding to the close D-shaft being movable toward the unlatched position. A release member cooperates with the actuator and is pivotably coupled to the first end of a transfer link. The second end of the transfer link extends toward the close D-shaft. When the actuator is moved toward the actuated position, it moves the release member, thereby moving the transfer link and pivoting the close D-shaft toward the unlatched position.
