The VW3A9116 is an IP31 conformity kit from Schneider Electric, designed specifically for the ATV61 and ATV71 variable speed drive families. The kit composition includes one manual, one IP31 cover, one IP54 casing, fixing accessories, and one EMC plate with cable clamps — everything needed to bring a standard drive up to IP31 ingress protection for panel or standalone installation.
The IP31 cover and IP54 casing allow the kit to seal the drive enclosure for environments where splash or dust ingress is a concern, provided the base drive is mounted in a suitable cabinet. The EMC plate with cable clamps provides a bonding point for shielded motor and control cables, reducing radiated emissions at the drive output — a practical consideration when the drive sits near sensitive instrumentation or runs long cable lengths.
