Individual carbon steel enclosure with stable enclosure body, two integrated mounting levels, screw-fastened rear panel and door. Roof and sides from a single piece with roll-formed frame. Fully compatible with the VX25 baying system. Enclosure widths ranging from 600 to 1800 mm and enclosures with 300-mm depth for building services applications. Improves efficiency as side panels do not have to be mounted, and large enclosure widths replace small bayed suites.
