The Schneider VW3A46104 is a passive filter designed to reduce current harmonics from variable-speed drives. It sits between the mains supply and the drive input, rated for 22 A input and 23 A output on a 400 V three-phase network at 50 Hz. One filter per drive is required, and the application list covers ATV61W, ATV61H, ATV71H, ATV71P, ATV71W, ATV630, ATV650, ATV930, and ATV950 drives — all at the 11 kW / 15 hp motor rating. The THDI performance varies by drive family: 10 % for ATV630, ATV650, ATV930, and ATV950; 16 % for the ATV61 and ATV71 series. That means on the newer Altivar Process drives, the filter knocks line current distortion down to 10 % of fundamental at full load.
Power factor and efficiency
The filter maintains a power factor of 0.99 at 100 % line current, 0.85 at 75 % load, and unity (1.0) at 150 % of nominal current. Efficiency is 98 %, so thermal losses are 206 W — figure that into your enclosure cooling budget. It can handle 1.5 × nominal current for 60 seconds, useful for short-duration overload events during motor startup.
Installation and environmental limits
The filter carries IP20 protection as standard, or IP55 when enclosure-mounted. Terminals accept 0.5…10 mm² on the main power connections and 2.5 mm² on the A/B control terminals. 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. Operating temperature range is 5…45 °C without derating; above that, derate 3 % per °C up to 60 °C. Above 1000 m altitude, derate 5 % per additional 1000 m. Storage in original packaging: -25…55 °C; transport: -25…65 °C. Humidity 5…85 % non-condensing.
