The VW3A9652 is a DNV-certified shock-absorbing mount kit from Schneider Electric, designed specifically for ATV61 and ATV71 variable speed drives in size 6 enclosures. The kit includes the fixing accessories and shock-absorbing mounts needed to satisfy DNV certification body requirements for marine and offshore applications.
The DNV certification is the key differentiator here — this isn't a generic shock mount. It's the kit that lets the drive installation pass marine-class vibration and shock testing per DNV rules. If your panel is going on a vessel, offshore platform, or any DNV-classed asset, this specific kit is what the surveyor expects to see. The shock-absorbing mounts decouple the drive chassis from the enclosure backplate, reducing transmitted vibration that could loosen terminals or fatigue PCB solder joints over the vessel's service life.
Deployment context
Mounts inside the ATV61/71 size 6 enclosure between the drive chassis and the backplate. The kit's fixing accessories are sized for the drive's mounting pattern — no panel modification needed if you're replacing a failed mount set on an existing installation. For new builds, factor the kit into the enclosure depth budget; the mounts add standoff height between drive and panel.
