A switchgear cabinet comprising a cabinet frame, first and second current converter devices, and an electrical connection clamping device. The first current converter device has first DC voltage positive and negative potential connection elements. The second current converter device has second DC voltage positive and negative potential connection elements. The electrical connection clamping device has an electrically conductive first clamping element and an electrically conductive second clamping element which is electrically insulated from the electrically conductive first clamping element, and a pressure-generating device which generates a pressure that pushes the second clamping element towards the first clamping element. The first clamping element is mechanically connected to the cabinet frame by an electrically non-conductive insulation body such that the first clamping element is electrically insulated from the cabinet frame. The invention provides a switchgear cabinet for housing current converter devices, wherein the current converter devices can be replaced quickly and easily.
