The Schneider Electric VW3A46175 is a passive filter from the Altivar accessory family, designed to reduce current harmonics on the line side of variable-speed drives. It's a three-phase, 480 V ±10 %, 60 Hz unit rated 380 A input and 395 A output, with a THDI of 5 % when paired with specific Altivar drives — ATV61H, ATV71H, ATV61Q, ATV71Q at 500 kW/700 hp, or ATV630 and ATV930 at 220 kW/350 hp.
The 395 A output rating governs the drive size it can support — it's sized for the 500 kW/700 hp ATV61/71 frames and the 220 kW/350 hp ATV630/930 frames. The 5 % THDI figure means it brings line current distortion down to that level under rated load, which helps meet IEC 61000-2-4 and G5/4 harmonic limits without an active front end. Thermal losses run 1510 W, so panel ventilation needs to account for that heat rejection — it's not a negligible dissipation figure.
Deployment context
The filter carries IP20 protection as standard, with IP55 available when enclosure-mounted. It's a panel-installed component, not a standalone cabinet — plan for the 1510 W thermal load in your enclosure cooling calculation. Electrical connection uses A/B terminals for control wiring (2.5 mm²) and X1-1 through X2-3 terminals for power (25–300 mm²).
