The VW3A9644 is a DNV certification kit from Schneider Electric, designed for Altivar ATV61 and ATV71 variable speed drives in size 11V. It provides the mechanical fittings — profiles, brackets, and shock-absorbing mounts — needed to satisfy the requirements of the DNV classification society for marine and offshore installations.
What the kit includes
The kit composition covers the fixing accessories — the mechanical profiles and brackets required for mounting the drive — plus shock-absorbing mounts. These are the hardware elements that adapt the standard drive chassis to meet DNV's vibration and shock criteria for marine duty.
