  • Patent number: 6509523
    Abstract: A switchgear cabinet with two profiled frame sections, assigned to one side of the switchgear cabinet, wherein the open side of the switchgear cabinet is partially closed or can be partially closed by at least one wall element. A horizontal cross brace is arranged between the vertical profiled frame sections, against which the wall element rests in an area of one of its horizontal lateral edges. An open transition area in the side of the switchgear cabinet between the cross brace and the cover and/or the bottom area of the switchgear cabinet is covered by a shield. For simplification, the shield is fastened on a fastening section of a holder from the direction of the interior of the switchgear cabinet. With the shield in an unmounted position, the holder is maintained by a locking element in a prepared mounting position.
