The Schneider Electric VW3A9545 is a pre-equipped IP54 floor-standing enclosure kit designed to house ATV61 or ATV71 variable speed drives in a sealed, floor-mounted cabinet. It ships as a complete assembly — upper and lower air ducts, seals, a plinth, roof extension, drive support, EMC plate, fixing accessories, a document holder, and an IP65 graphic display terminal remote mounting kit. The enclosure includes a 24 V DC, 600 mA supplementary power supply plus the drive's own 24 V DC 21...27 V supply drawing under 200 mA. Cable entry is via the enclosure bottom or from the left side.
The IP54 rating means the enclosure protects against dust ingress and water splashes from any direction — suitable for indoor industrial environments where washdown is occasional, not continuous. The ambient air temperature range of 0...45 °C outside the enclosure and 0...50 °C inside sets the thermal boundary: if the drive dissipates enough heat to push internal ambient above 50 °C, the enclosure needs forced ventilation or a larger cabinet. The 24 V DC supplementary supply (600 mA) powers the IP65 remote display terminal and any auxiliary control circuits; the drive's own 24 V DC supply (21...27 V, <200 mA) feeds the drive control logic and I/O.
