The VW3AE0429 is an ammeter accessory designed for Schneider Electric Altivar 71 Plus and Altivar 61 Plus drives, specifically for floor-standing enclosures with separate air flows or the compact version. It is intended for 12-pulse configurations, providing current indication on the drive front panel.
Fit and deployment context
This ammeter mounts inside the Altivar floor-standing enclosure, wired into the 12-pulse drive's current transformer circuit. It is a control accessory, not a standalone meter — it relies on the drive's internal sensing. If you are maintaining an existing Altivar 71 Plus or 61 Plus installation and the ammeter has failed, this is the direct drop-in. For new builds, the Altivar 71 Plus and 61 Plus are themselves legacy platforms; a drive upgrade would require a different ammeter solution.
