The Schneider VW3A4612 is a passive filter designed to reduce current harmonics on Altivar variable-speed drives. Rated at 289 A and 400 V ±10 %, 50 Hz, it delivers a THDI of 10 % on the ATV61 and ATV71 drives listed — meaning it cleans up the line-side current distortion to that level under rated load.
Mounts as an external line filter — IP20 enclosure, bare-wire connection (16.5 mm diameter). Quantity per drive varies by model: one filter for a 160 kW drive (ATV61HC16N4 or ATV71HC16N4), two for 280–355 kW frames, three for 500 kW frames. Plan the panel space accordingly.
Performance details
Efficiency is 98 %. Cos phi varies with load: 1 at 150 % line current, 0.99 at 100 %, 0.85 at 75 % — so the filter maintains near-unity power factor across a wide load band. Max current is 1.5× nominal; Class F insulation. Operating temperature range is 5–40 °C without derating, 40–55 °C with 3 % per °C derating. Altitude derating applies above 1000 m (5 % per 1000 m).
