The VW3AP0353 is an IP54 conformity kit from Schneider Electric, designed for Altivar Process ATV600 and ATV900 drive systems in the 355 to 500 kW power range, size 3A. It comprises two upper air ducts, one lower air duct, and one 200 mm plinth — the hardware needed to raise the standard enclosure's ingress protection to IP54. This is not a standalone accessory; it can only be ordered in combination with a standard enclosure.
Because it's a kit that must ship with an enclosure, the procurement path is: specify the VW3AP0353 line item on the drive-system order.
Integration notes
The kit is sized for ATV600 and ATV900 drives in the 355–500 kW band, frame size 3A. The two upper ducts and single lower duct route cooling air through the IP54 plinth; the 200 mm plinth provides the base height for the sealed enclosure. If you're retrofitting an existing drive that's running without IP54, verify the enclosure model matches the kit's plinth length and duct configuration — the ducts are specific to the drive's airflow path.
