What this kit does and why it matters
The VW3A9623 is a DNV certification kit for Schneider ATV61 and ATV71 variable speed drives. It bundles an additional EMC input filter, fixing accessories, shock-absorbing mounts, and EMC filter supports — everything needed to pass the vibration and EMC requirements of DNV marine certification in a single package.
What is in the box
The kit includes an additional EMC input filter, fixing accessories, shock-absorbing mounts, and EMC filter supports. The overall package dimensions are 193 x 445 x 121 mm. This is a mounting and fixing accessory category part, not a standalone filter — it integrates mechanically and electrically with the drive frame.
Designed specifically for ATV61 and ATV71 variable speed drives. The shock-absorbing mounts suggest a panel or enclosure installation where the drive needs isolation from hull vibration — typical for marine propulsion or pump drives on vessels. The EMC filter addresses conducted emissions that could interfere with shipboard navigation or comms gear.
