Abstract: A cable inlet device consists substantially of an open frame part and at least one sealing insert arranged therein. This cable inlet device is attached to a switchgear cabinet so that the sealing insert and the frame part of the cable inlet device terminate flush with the opening. When the switchgear cabinet is closed, for example by a switchgear cabinet door or switchgear cabinet wall or the like, this door or wall is sealingly pressed with a counterpart seal against the cable inlet device. For replacement of cables it is merely necessary for the switchgear cabinet door/switchgear cabinet wall to be opened and for the cable to be changed to be removed together with the corresponding sealing element, and for the new cable to be provided with a matching sealing element and to be inserted.
