The VW3A9541 is a pre-equipped IP54 floor-standing enclosure kit from Schneider Electric, designed to house ATV61 or ATV71 variable speed drives in a sealed, floor-mounted cabinet. It ships as a kit containing the roof extension for an IP65 graphic display terminal, a remote mounting kit, an EMC plate, a document holder, a 24 V DC 600 mA supplementary power supply, plinth, seals, drive support, upper and lower air ducts, fixing accessories, a handle with push-button opening mechanism, and identification labels. The enclosure is rated for ambient air temperatures of 0 to 50 °C inside the enclosure, 0 to 45 °C outside.
Cable entry is via the enclosure bottom or from the left side, which gives the panel builder flexibility in routing power and control cables. The colour scheme is RAL 7022 for the plinth and RAL 7032 for the case — a standard industrial grey that matches most Schneider drive installations. The kit includes a 24 V DC supplementary power supply rated for 600 mA, which powers the graphic display terminal and any auxiliary loads inside the enclosure.
