1. A breaking module for an electrical switchgear apparatus, comprising: -at least one vacuum cartridge(10) comprising a body (17) forming an enclosure (18) containing a pair of separable contacts (22, 24), one of said contacts (24) being securely affixed to a movable metal rod(32), a part of the rod (32) protruding out from the enclosure at a first axial end of the body (17) of the cartridge (10); -a support frame (12) of the cartridge; comprising in addition a fixing and guiding collar (100) comprising: -an aperture (120) forming an axial guide sheath of the rod (32) of the cartridge, performing guiding of the rod (32) in translation with respect to the collar (100) according to a geometric axis of the aperture (120); -radial positioning surfaces (108) co-operating with the body (17) of the cartridge and preventing any radial movement of the body (17) of the cartridge with respect to the geometric axis of the aperture (120) of the collar (100); -means for fixing to the support frame of the cartridge. 2. The breaking module according to claim 1, wherein -the frame is provided with guiding slides (130); -the collar (100) is in the form of a slide-rack so as to slide in said guiding slides(130) in a direction perpendicular to the geometric axis of the aperture (120). 3. The breaking module according to any of preceding claims, wherein the means for fixing comprise elastic clips (118) forming a fixing means by clipping. 4. The breaking module according to any of preceding claims, wherein the collar (100) is composed of two parts (101, 102) able to take an open position with respect to one another enabling radial insertion of the rod (32) of the cartridge and a closed position wherein the radial positioning surfaces (108) co-operate with the body of the cartridge and the aperture cooperates with the rod (32). 5. The breaking module according to claim 4, wherein the two parts of the collar (101, 102) are articulated on one another by a hinge (103). 6. The breaking module according to claim 4, wherein the two parts (101, 102) of the collar (100) are secured to one another in the closed position by fixing means. 7. The breaking module according to any of preceding claims, wherein the collar (100) is provided with axial positioning surfaces (107) forming a seat for a section of axial end (20) of the body (17) of the cartridge. 8. The breaking module according to any of preceding claims, wherein the collar (100) is made of plastic material. 9. The breaking module according to any of preceding claims, comprising a single vacuum cartridge (10). 10. An electrical switchgear apparatus comprising at least one module according to any of preceding claims, and a drive mechanism (13) of the rod of said module.
