The VW3AE0709 is a cable-entry accessory that mounts to the top of a Schneider Altivar floor-standing enclosure — specifically the variants with separate air flows or the compact version. It belongs to the Altivar 71 Plus, Altivar 61 Plus-LH, and Altivar 71 Plus-LH product ranges.
This part is classified as Obsolete by the manufacturer. For existing installations that require this specific top-entry cable gland plate, the only practical sourcing channel is the surplus and independent-distribution market.
