The Schneider Electric VW3A46156 is a passive filter designed to reduce current harmonics on Altivar ATV61 and ATV71 variable speed drives rated up to 500 kW / 700 hp. It handles a continuous output current of 395 A at a supply voltage of 480 V ±10 %, 60 Hz, three-phase. Two of these filters are required per drive for the target motor ratings. THDI sits at 10 % for the listed drive-and-motor combinations, which keeps harmonic injection within IEC 61000-3-12 and G5/4 engineering recommendation limits. Efficiency is 98 %, with thermal losses of 1175 W — that heat has to go somewhere, so factor it into your enclosure ventilation. Power factor varies with load: cos φ is 1 at 150 % of line current, 0.99 at 100 %, and 0.85 at 75 %. The filter can handle 1.5× nominal current for 60 seconds — useful for short-duration overloads during startup or transient events.
IP20 base rating; IP55 when enclosure-mounted. The filter uses A/B terminals with 2.5 mm² capacity for the control connections and X1-1…X2-3 terminals accepting 25…300 mm² for the power wiring. Mounting altitude derating kicks in above 1000 m — 5 % current reduction per 1000 m up to 4000 m. Operating temperature range is 5…45 °C without derating, 45…60 °C with a 3 % per °C derating. 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. Insulation class F. Storage temperature in original packaging is -25…55 °C; transport range extends to -25…65 °C.
