The VW3AE0820 is a 200 mm plinth for Altivar floor-standing enclosures with separate air flows or compact versions, belonging to the Altivar 61 Plus and Altivar 71 Plus drive ranges. It raises the enclosure base to provide cable entry clearance and bottom-side ventilation — a mechanical fitment, not an electrical component.
Sourcing reality — obsolete, not gone
If the enclosure footprint allows, a field-fabricated riser or a generic 200 mm plinth from a cabinet supplier may serve the same mechanical function, but that is a site-level judgement, not a manufacturer cross-reference.
What it fits and why it matters
The plinth is destined for Altivar floor-standing enclosures with separate air flows or compact versions — the 61 Plus and 71 Plus drive families. If you are rebuilding or extending a drive cabinet that originally had this plinth, the 200 mm height provides the clearance for bottom cable entry and maintains the thermal separation between the drive cooling air path and the cable compartment. Omitting it or substituting a different height shifts the cable bend radius and may compromise the IP rating at the base.
