The Schneider Electric VW3A46176 is a passive filter for Altivar variable speed drives, designed to reduce current harmonics to a THDI of 5 % across a range of drive ratings from 220 kW/350 hp up to 560 kW/800 hp, including ATV61, ATV71, ATV630, and ATV930 series. Rated at 450 A output and 436 A input on a 480 V +/- 10 %, 60 Hz three-phase supply, it delivers 98 % efficiency with thermal losses of 1852 W. The filter achieves a power factor of 0.99 at 100 % line current, 0.85 at 75 %, and unity (1) at 150 % of line current — the latter sustained for 60 seconds at 1.5x nominal current.
Harmonic mitigation and standards compliance
This passive filter is the component that brings the drive installation into compliance with IEC 61000-3-2, IEC 61000-3-4, IEC 61000-3-12, IEC 61000-2-2, IEC 61000-2-4, and the UK G5/4 engineering recommendation — the set of standards that govern harmonic emission limits on industrial and commercial networks. The THDI of 5 % applies across all listed drive-and-motor combinations, meaning the filter holds harmonic distortion to that level regardless of whether it's paired with an ATV61H at 280 kW/450 hp or an ATV930 at 250 kW/400 hp.
IP20 rated with IP55 available for enclosure mounting. Operating temperature range is 5 to 45 °C without derating; above that, derate 3 % per °C up to 60 °C. Storage in original packaging at -25 to 55 °C, transport to 65 °C. Altitude derating applies above 1000 m: 5 % current reduction per additional 1000 m up to 4000 m. Vibration resistance per IEC 60068-2-6: 2 mm peak-to-peak at 5-13.2 Hz, 0.7 gn at 13.2-150 Hz. Electrical connection uses A/B terminals for 2.5 mm² and X1-1...X2-3 terminals for 25 to 300 mm² conductors. Class F insulation. Quantity per drive varies: one filter for ATV630/930 wall-mount at 250 kW/400 hp, up to three for ATV61H at 560 kW/800 hp.
