The VW3AE0615 is a motor choke from Schneider Electric's Altivar 71 Plus and Altivar 61 Plus range, designed as a protection accessory for floor-standing enclosures with separate air flows or compact versions. Its job is to limit dv/dt and peak voltage at the motor terminals, reducing stress on winding insulation on longer cable runs — a common fix when a drive-to-motor distance exceeds the drive's native rating.
Mounts inside the Altivar floor-standing enclosure — not a standalone panel component. If you're retrofitting into an existing cabinet, verify the enclosure variant (separate air flows vs. compact) lines up with the destination marking on the accessory. The choke itself is a passive series element; no wiring complexity beyond the motor cable path.
