The VW3AE0603 is a motor choke designed for Schneider Altivar floor-standing drives with separate air flows or compact enclosures — specifically the Altivar 71 Plus, Altivar 71 Plus-LH, Altivar 61 Plus, and Altivar 61 Plus-LH series. It sits between the drive output and the motor cable, limiting voltage spikes and reducing bearing currents from long cable runs. That makes it a protection accessory for the motor, not the drive itself.
Schneider lists this part as Obsolete. If you are maintaining an Altivar 71 or 61 Plus installation, this choke is a critical spare — one in the cabinet before it fails.
