The VW3A9648 is a DNV certification kit for Schneider Electric ATV61 and ATV71 variable speed drives, sized for the 15V frame. It includes shock-absorbing mounts, fixing accessories, and the mechanical profiles and brackets needed to secure the drive for marine-class vibration and shock — meeting DNV requirements without sourcing separate hardware.
This kit is listed as obsolete. No official replacement order code is published.
The kit is specific to the ATV61 and ATV71 size 15V drive footprint. If you're retrofitting a drive from a different frame size or series, the mounting hole pattern and bracket geometry won't transfer — this isn't a universal adapter. For a shipboard panel where the drive is already bolted in, having the DNV kit on hand simplifies class-survey documentation.
