The VW3AP0303 is an IP54 conformity kit from Schneider Electric's Altivar Process range, designed for compact drive systems in the 355 to 500 kW power band. It pairs with standard enclosures for ATV600 and ATV900 series drives to bring the assembly up to IP54 protection — meaning the enclosure seals against dust ingress and water spray from any direction, a common requirement for washdown areas or outdoor shelters where a drive cabinet sits exposed.
What's in the kit and how it fits
The kit comprises two upper air ducts, one lower air duct, and one plinth of 200 mm length. These components redirect airflow through the enclosure's filtered intake and exhaust, maintaining the drive's thermal design while the IP54 seal is intact. The plinth raises the cabinet base to keep cable entries above floor-level splash zones. This is an enclosure accessory — it is not a standalone part. The condition of use states it cannot be ordered alone; it must be specified together with a standard enclosure from the same product family. For a panel builder or MRO planner, that means the BOM line for VW3AP0303 always accompanies a cabinet order, never sits on its own in the spares crib.
