US 6,445,559 B1 · Double wide center handle

Abstract

A handle assembly and an alignment member are mounted on a joining structure that fixedly joins a pair of circuit breakers together. A support assembly is mounted in a cassette that removably receives the circuit breakers and joining structure. The support assembly includes a support bar that is moveable between an inward position and an outward position and that provides vertical support to the joining structure and to the circuit breakers to resist sagging of the circuit breakers at the joining structure to facilitate alignment of the circuit breakers with the cassette and installation of the circuit breakers therein. The handle assembly includes a handle that is moveable between a retracted position and an extended position. A horizontal tensile force applied to the handle in the extended position is, in turn, equally applied to each of the circuit breakers to simultaneously disengage the circuit breakers from the stabs on the cassette and to resist the circuit breakers from binding up within the cassette during removal therefrom.
