The VW3A99ACA01 is a bottom support for the Altivar Process Modular drive range, designed for single-drive architecture in IP21 cabinets. It is the structural bracket that carries the standard power module inside the enclosure — not a functional electronic component, but the mechanical interface that positions and stabilizes the drive within the cabinet.
What it does in the cabinet
This support mounts inside an IP21-rated cabinet and accepts one standard power module from the Altivar Process Modular family. The kit composition is a single bottom support — one piece per drive position. It is an installation accessory, not a functional module, so there are no electrical ratings to match; the fit is purely mechanical, governed by the cabinet depth and the module's mounting footprint.
