Abstract
A breaking module for an electrical switchgear apparatus comprises a vacuum cartridge comprising a body and a support frame of the cartridge. The cartridge is provided with a metal rod movable in translation and driving a movable contact. A collar both performs radial positioning of the body of the cartridge with respect to the frame and constitutes a guide sheath of the rod. For fitting, the collar can be opened so as to insert the rod radially therein. Once the body of the cartridge has been encircled, the collar is inserted radially in guide grooves of the frame.
