A low voltage, medium-voltage or high-voltage switchgear assembly has at least one short-circuiting system where a movable contact can be coupled with a fixed contact by means of a propellant charge or a gas generator. The short-circuiting device has a vacuum interrupter chamber and the vacuum area in which the fixed contact piece is placed which is subdivided via a membrane which is provided with a weak breaking line and which can be penetrated by the moving piston system to the contact piece during switching. |
