The VW3AE0631 is a motor choke from Schneider Electric's Altivar accessory line, designed for the Altivar 71 Plus and Altivar 61 Plus drive families. It mounts in the floor-standing enclosure variant with separate air flows or the compact version, serving as a protection accessory on the motor output.
Schneider has classified this part as obsolete.
The choke is a bolt-in accessory for the Altivar floor-standing enclosure with separate air flows or the compact version. It sits on the motor output side of the drive, between the drive terminals and the motor cable, to limit voltage rise rates and reduce capacitive coupling currents in longer cable runs. No DIN-rail mounting — it's panel-mounted inside the drive enclosure.
