Abstract
A securing mechanism is provided for an electrical switching apparatus, such as a circuit breaker, which is movable into and out of an installed position within a switchgear enclosure. The securing mechanism includes a mount coupled to the circuit breaker, and a movable assembly movably coupled to the mount and including an engagement member. The movable assembly moves among first and second positions corresponding to the circuit breaker not being fully installed within the switchgear enclosure and being disposed in the installed position, respectively. When the circuit breaker is moved toward the installed position, the engagement member engages the switchgear enclosure and moves the movable assembly toward the second position, in which the engagement member securely engages the switchgear enclosure to resist undesired movement of the circuit breaker with respect to the switchgear enclosure.
