What the DNV Kit Delivers
The VW3A9643 is a DNV certification kit for Schneider Electric ATV61 and ATV71 variable speed drives, assembled to satisfy the requirements of the DNV classification body for marine and offshore installations. The kit bundles an EMC input filter, a line choke, shock-absorbing mounts, and fixing accessories — everything needed to bring a standard drive package into line with DNV's conducted-emission and mechanical-vibration limits in a single order code.
DNV Compliance Package — What It Covers
The EMC input filter and line choke together address the conducted-emission profile that DNV surveyors look for on variable-speed drives in shipboard and offshore installations. The shock-absorbing mounts handle the vibration spectrum typical of engine-room and deck-mounted enclosures. Because the kit was designed as a matched set for the ATV61/ATV71 platform, the filter and choke are pre-sized for the drive's nominal input current — no separate coordination calculation needed at the panel builder's bench.
