The VW3AE0920 is an air-conditioning accessory for Schneider Electric Altivar floor-standing enclosures with separate air flows or compact versions, designed for the Altivar 61 Plus and Altivar 71 Plus drive ranges. This is not a drive or a controller — it is a thermal-management unit that mounts into the enclosure to maintain operating temperature for the drives installed inside, which is a common requirement when drives are packed into sealed cabinets with limited natural convection.
For procurement, this means the VW3AE0920 is sourced through independent distribution and surplus channels.
Fit verification for your BOM line
This unit is specifically intended for Altivar floor-standing enclosures with separate air flows or the compact version — not for wall-mount or panel-mount drive enclosures. If your installation uses a standard Altivar 61 Plus or 71 Plus floor-standing cabinet, this is the correct thermal-management accessory. Fit is determined by mechanical compatibility with the enclosure model and the drive series listed.
