Abstract
A dampening mechanism for an electrical for an electrical switching apparatus, such as a draw-out circuit breaker, includes a mounting bracket coupled to the circuit breaker, a pivot member, at least one biasing element, and a damper. The circuit breaker is movable into and out of an installed position within a switchgear enclosure. The pivot member pivots between first and second positions corresponding to the circuit breaker not being fully installed and being disposed in the installed position, respectively. The biasing element biases the pivot member toward the first position. When the circuit breaker is moved toward the installed position, the second end of the pivot member engages at least one of a back panel and a ledge of the enclosure, thereby pivoting the pivot member toward the second position. When the pivot member is disposed in the second position, the damper is biased against the ledge of the enclosure to dampen undesired vertical motion of the circuit breaker.
