The Schneider Electric VW3A9313 is a substitution kit designed for one specific migration path: replacing an ATV58HD54N4 variable speed drive with an ATV71HD37N4. It is an adaptation accessory that provides the mechanical and electrical interface to mount the newer ATV71 frame into an existing ATV58 footprint, preserving the cabling and panel layout where possible.
This part is classified as obsolete by the manufacturer. The is listed as mature, which in Schneider Electric's product lifecycle terminology precedes formal end-of-life notification. For procurement purposes, treat VW3A9313 as a last-time-buy candidate: no guarantee of ongoing factory production.
The kit addresses a specific panel integration constraint: the ATV71HD37N4 has a different mechanical footprint and power-terminal layout than the ATV58HD54N4 it replaces. Without VW3A9313, a retrofit would require re-drilling the mounting plate, re-running power cables, and re-terminating control wiring. The adaptor preserves the existing gland-plate entry points and bus-bar positions, reducing downtime during the swap.
