The VW3AE0147 is a circuit-breaker protection accessory from Schneider Electric's Altivar drive family, designed for Altivar floor-standing enclosures with separate air flows or compact versions. It serves as the branch-circuit protection device within the drive cabinet, sized for the Altivar 61 Plus, Altivar 61 Plus-LH, Altivar 71 Plus, and Altivar 71 Plus-LH series.
This breaker mounts inside the Altivar floor-standing enclosure, not on a DIN rail in a separate panel. The accessory designation means it integrates with the drive's internal bus structure and enclosure layout — it is not a standalone panel-mount breaker. If you are retrofitting a drive cabinet that originally shipped with this breaker, the enclosure cutouts and bus-bar connections are already sized for it.
