The VW3A4632 is a passive filter from the Altivar accessory range, designed to reduce current harmonics on the line side of Schneider Altivar ATV61 and ATV71 variable speed drives. It's a three-phase, 400 V +/- 10 % unit rated at 289 A, with a THDI of 5 % when paired with specific drive models like the ATV61HC16N4 (160 kW/250 hp motor) or the ATV71HC50N4 (500 kW/700 hp motor). The filter achieves a power factor of 0.99 at full load and holds efficiency at 98 %, meaning the losses are low enough that panel ventilation requirements stay manageable for a filter of this class.
Schneider Electric lists the VW3A4632 as obsolete.
The 289 A rating sets the line-side current capacity. The filter is sized for drives up to 500 kW/700 hp (ATV61HC50N4 or ATV71HC50N4), but note the quantity per drive: larger frames need multiple filters — two for a 280 kW drive, three for a 500 kW drive. The THDI of 5 % is the harmonic performance at the drive's nominal operating point, which keeps line distortion within typical IEEE 519 guidelines for a six-pulse drive front end. Operating temperature range is 5...40 °C without derating; above that, derate current by 3 % per °C up to 55 °C. At altitudes over 1000 m, derate 5 % per additional 1000 m. The IP20 enclosure means it's for indoor panel mounting only — not for washdown or outdoor locations.
