The VW3A46129 is a passive filter designed to reduce current harmonics from Schneider Altivar variable speed drives. It's sized for 400 V three-phase networks at 50 Hz, with a rated input current of 86 A and output current of 90 A. The filter targets THDI reduction to 5 % when paired with ATV630, ATV650, ATV930, or ATV950 drives at 37 kW/50 hp, and to 10 % with ATV61H, ATV71H, ATV61W, or ATV71W drives at 45 kW/60 hp.
At 98 % efficiency, the filter dissipates 747 W of thermal losses — that's heat you need to account for in your enclosure ventilation or air conditioning budget. The filter is rated IP20 as standard, or IP55 when enclosure-mounted, so it's suitable for cabinet installation in clean environments or for washdown areas with the right enclosure. The cos phi curve tells you how the filter behaves under load: unity power factor at 150 % of line current, 0.99 at full load, and 0.85 at 75 % load. That means the filter maintains near-unity power factor across most of the operating range, which helps avoid utility penalties for poor power factor. Operating temperature range is 5...45 °C without derating, and up to 60 °C with a 3 % per °C derating. Above 1000 m altitude, derate current by 5 % per additional 1000 m. The filter can handle 1.5 x nominal current for 60 seconds — useful for motor starting transients.
The filter is designed to meet IEC 61000-2-4, IEC 61000-3-4, IEC 61000-3-2, IEC 61000-2-2, IEC 61000-3-12, and the UK G5/4 engineering recommendation. That covers both the emission limits and the compatibility levels for industrial networks. Class F insulation throughout. Production status is active per the manufacturer's lifecycle record — this is a current catalog item, not a phase-out or NRND part.
One filter is required per drive for the listed ATV630, ATV650, ATV930, ATV950, ATV61, and ATV71 models at the specified motor ratings. The power terminals accept 10...70 mm² conductors, with control terminals at 2.5 mm². 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.
