The Schneider Electric VW3A9637 is a DNV certification kit designed for the ATV61 and ATV71 variable speed drives in size 13A. It provides the mechanical fittings, profiles, brackets, and shock-absorbing mounts required to satisfy the requirements of the DNV certification body for marine and offshore applications.
What the Kit Delivers
The kit is a mounting and fixing accessory category item. It includes the metal profiles and brackets that adapt the drive chassis for the shock and vibration profile required by DNV classification, plus the shock-absorbing mounts themselves. No electrical components or wiring changes are involved — this is purely a mechanical retrofit for the ATV61/ATV71 size 13A frame.
