The Schneider VW3A46127 is a passive filter for Altivar variable speed drives, sized to knock down current harmonics on the line side. It's a one-per-drive add-on for ATV630, ATV650, ATV930, and ATV950 wall-mount units at 22 kW/30 hp, and for ATV61H, ATV61W, ATV71H, and ATV71W units at 30 kW/40 hp. Rated at 58 A input and 60 A output on a 400 V +/- 10 %, 50 Hz three-phase supply, it pulls the line current THDI down to 5 % for the ATV630/650/930/950 family — that's the number that matters for IEEE 519 compliance on a standard industrial service. Efficiency sits at 98 %, with 574 W of thermal losses to vent inside the enclosure. The filter meets IEC 61000-3-4, IEC 61000-3-12, and IEC 61000-2-2 (G5/4) — so it's built for the harmonic limits European utilities enforce.
The 60 A output rating governs the drive size it pairs with. Match the filter to the drive's input current — not the motor FLA — and confirm the 400 V nominal line. The 50 Hz +/- 2 % frequency window means it's tuned for 50 Hz grids; on a 60 Hz supply the filter's harmonic attenuation shifts, so verify with the drive application note before committing. Cos phi varies with load: 1 at 150 % line current (overload condition), 0.99 at full load, and 0.85 at 75 % load. That's the filter's natural power factor correction curve — it doesn't add PF correction capacitors, but it keeps displacement factor near unity at rated current. The filter can handle 1.5 x nominal current for 60 seconds — enough to ride through a drive inrush or a momentary overload without dropping out. Ambient temperature range is 5 to 45 °C without derating; above that, derate 3 % per °C up to 60 °C. Above 1000 m altitude, derate 5 % per additional 1000 m.
IP20 as a standalone unit, IP55 when enclosure-mounted — so it's fine inside a ventilated panel but needs the cabinet's own sealing for washdown areas. 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. Mount it on the panel backplate near the drive line input; long cable runs between filter and drive reduce the filter's effectiveness. Electrical connection uses terminals: X1-1 through X2-3 accept 2.5 to 50 mm² cable, plus a separate 2.5 mm² terminal for the A/B connection. Relative humidity 5 to 85 % without condensation.
