The VW3A9529 is a cable clamp kit for the Schneider Electric Altivar 312 drive series, specifically sized for frame size 4. The kit contains screws and dampers in stainless steel, serving as the connection accessory that secures the motor cable entry at the drive's bottom gland plate.
This part is officially obsolete per the manufacturer's lifecycle record. No direct successor order code is published, which means the Altivar 312 platform itself has been superseded by later drive families (Altivar 320, Altivar 630).
The 'size 4' designation ties directly to the Altivar 312 enclosure frame — this kit fits ATV312HU75M3, ATV312HU75N4, and ATV312HD11M3X drives. The stainless steel construction matters in washdown or corrosive environments where a standard plated clamp would rust. If your panel uses a different drive family, the gland-plate hole pattern and screw spacing will not match; this is not a universal cable gland.
