The Schneider VW3A9549 is a pre-equipped IP54 floor-standing enclosure kit designed to house an ATV61 or ATV71 variable speed drive in a protected, floor-mounted installation. The kit includes an air/air heat exchanger, a graphic display terminal remote mounting kit with a push-button-operated opening mechanism, an EMC plate, a 24 V DC 600 mA supplementary power supply, lower and upper air ducts, drive support, roof extension, fixing accessories, seals, plinth, document holder, and identification labels. The internal 24 V DC supply delivers 21...27 V at under 200 mA for the drive's control section; the separate 600 mA supply powers the enclosure's cooling and display. Cable entry is via the enclosure bottom or from the left, with a colour scheme of RAL 7022 plinth and RAL 7032 case.
This part is officially obsolete.
Deployment context
Designed for floor-standing installation in a plant environment where IP54 ingress protection is needed — dust and splashing water. The air/air heat exchanger keeps the drive within the 0...50 °C internal ambient range while the outside ambient can reach 0...45 °C. The remote-mount graphic display kit allows the HMI to be positioned on the enclosure door for operator access.
