The Schneider Electric VW3AE2701 is an isolation accessory — specifically a selector for IT system — designed for Altivar floor-standing enclosures with separate air flows or compact versions, covering the Altivar 71 Plus, 71 Plus-LH, 61 Plus, and 61 Plus-LH drive ranges. Its condition of use is explicitly for IT networks (ungrounded or impedance-grounded systems), which is the key fit criterion: if your line-side supply is an IT network configuration, this selector isolates the drive's power section correctly; if your supply is TN or TT, this accessory is not the right pick.
The VW3AE2701 is officially obsolete per the manufacturer's lifecycle record.
This accessory mounts inside the Altivar floor-standing enclosure variant that uses separate air flows — the selector physically installs on the power section to reconfigure the DC-bus grounding for IT network compliance. The kit should include the selector switch, wiring harness, and mounting hardware; verify the carton contents match the panel's existing wiring scheme before committing the kit.
