Abstract

Abstract The present invention relates to a switchboard cabinet comprising a box-like cabinet body with an opening, a door which seals the opening of the cabinet, and a door frame provided in the opening of the cabinet connected to the inner panels of the cabinet body, whereby when the door is closed, a frame sealing member in the door frame bears against a sealing element provided inside the door, and the door is provided with a continuous inwardly bent perimeter flange at a right angle to the surface of the door. The joint between the cabinet body and the door, when it is closed, may be completely sealed from the weather by means of a cover strip fastened in a recess between the cabinet body and door frame which extends over and beyond the door and has a sealing lip which seals against the perimeter flange of the cabinet door, so that the cabinet is suitable for outdoor installation.
