The VW3A9315 is a substitution kit from Schneider Electric that adapts an ATV71 variable speed drive to replace an ATV58 unit in the HD64...79N4 power range. It is classified as an adaptation accessory for variable speed drives.
The ATV58 series has been superseded for years; if you are maintaining a line that still runs one, the VW3A9315 kit is the documented path to upgrade the drive without re-cabling the panel. The kit itself carries no separate ratings — its job is purely mechanical and electrical adaptation between two drive generations.
