The Schneider VW3A4661 is a passive filter designed to reduce current harmonics on Altivar ATV61 and ATV71 variable-speed drives. It mounts one filter per drive for models from 0.75 kW up to 3 kW — covering the H, P, and W frame variants across both the ATV61 and ATV71 families. Rated at 6 A continuous with a 480 V ±10 % 60 Hz three-phase supply, it delivers 98 % efficiency and holds the input current THDI to 10 % for the H-series drives and 5 % for the W-series drives. That 5 % figure on the W-series is the tighter spec — relevant if your site has a utility-imposed harmonic limit or you're feeding sensitive loads on the same bus. The filter's power factor correction is load-dependent: cos φ sits at 0.99 at full load (100 % line current), drops to 0.85 at 75 % load, and reaches unity (1.0) at 150 % of nominal current. The unity figure at overload is a transient characteristic, not a steady-state operating point.
IP20 enclosure — intended for clean, dry panel interiors. Terminal blocks accept up to 16 mm² conductors. Ambient operating range is 5 °C to 40 °C without derating; above 40 °C up to 55 °C, derate current 3 % per °C. Above 1000 m altitude, derate 5 % per additional 1000 m. Storage range is -25 °C to 55 °C.
Schneider has classified the VW3A4661 as obsolete.
