Abstract
A multipole electrical switchgear apparatus comprises a drive mechanism equipped with a pole shaft and a plurality of breaking modules. Each module comprises a vacuum cartridge moved by a movable rod articulated on a transmission lever. The pole shaft is linked to the transmission levers by means of a connecting rod. This common connecting rod gives the kinematic transmission system a great strength. Furthermore, it enables switchgear apparatuses having variable distances between breaking modules to be produced inexpensively, based on a standard pole shaft. Finally, it enables differentiation of the switchgear apparatuses to be delayed.
