The VW3AE0105 is an isolating handle for the main switch on Schneider Altivar floor-standing enclosures — specifically the versions with separate air flows or the compact variant. It is a mechanical handle, not an electrical component; it provides the external lever to manually isolate the drive's main disconnect switch for lockout/tagout during service. This handle is listed for the Altivar 71 Plus, Altivar 61 Plus, Altivar 61 Plus-LH, and Altivar 71 Plus-LH ranges. If your BOM references any of those drive families in a floor-standing cabinet, this is the factory-matching handle for the main switch.
What to expect when sourcing
Because this is a mechanical accessory with no electronics, there is no firmware revision, no compliance documentation beyond what the original drive enclosure carried, and no pin-compatible alternative within the same family. The closest functional match is another isolating handle from the same Altivar enclosure series, but the mounting geometry and handle throw differ between enclosure variants — verify the enclosure model before substituting.
