DISCONNECT OPERATING HANDLES SUITABLE FOR CIRCUIT BREAKERS AND RELATED BUCKET ASSEMBLIES AND HANDLE INTERLOCKS

摘要

Disconnect operating handles for circuit breakers are configured with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input. The disconnect operating handles include pivoting lockout levers that can automatically “pop” out to expose the lockout space for a padlock when a user touches the lever in an appropriate location.

主权项

1. A bucket assembly for a circuit breaker, comprising:
a rotary operating mechanism disconnect handle attached to the bucket assembly having a defined ON position and OFF position associated with conduction and non-conduction, wherein the operating mechanism disconnect handle comprises:
a base fixedly attached to the bucket assembly;an outer cover with an elongate channel attached to the base;an elongate lockout lever having a primary body with opposing spaced apart first and second end portions held in the elongate channel of the outer cover, the second end portion of the elongate lockout lever configured to be able to pivot outward from the elongate channel and expose a lockout passage residing under an outer surface of the lever;a lever pivot pin attached to the elongate lever to pivotably hold the lever in the elongate channel; andat least one resilient member that extends into the bucket assembly that is in communication with the lever and resides under the primary body of the lever, and wherein, in operation, the outer cover with the elongate lever rotates to the defined ON and OFF positions while the base remains in a fixed position attached to the bucket assembly.
