The VW3AE0911 is an air conditioning accessory from Schneider Electric's Altivar range, designed specifically for the Altivar 61 Plus and Altivar 71 Plus floor-standing enclosures with separate air flows or compact versions. This is a dedicated cooling unit, not a general-purpose fan or filter — it's sized and ducted to match the thermal profile of those drive enclosures.
Schneider has marked the VW3AE0911 as obsolete.
This unit bolts onto Altivar floor-standing enclosures that use separate air-flow routing or the compact enclosure variant. It's not a universal cabinet cooler; the mounting pattern, duct interface, and electrical connection are specific to those drive cabinets. If you're swapping a failed unit on an existing line, the enclosure model number confirms fit — no adapter plate needed.
