It's a line-side filter, not a motor dV/dt or sine-wave output filter — its job is to bring the drive's input current total harmonic distortion (THDI) down to levels that keep the plant within IEC 61000-3-4 and IEC 61000-3-12 limits, avoiding nuisance tripping of upstream protection and penalties from the utility. Rated for a 10 A input current and 400 V AC ±10 % at 50 Hz, it handles drives in the 4 kW to 5.5 hp range. One filter per drive is required — no sharing across multiple drives. The filter achieves 98 % efficiency, so the 131 W of thermal losses it sheds is the only heat you need to manage in the enclosure. ## THDI performance by drive family The THDI reduction depends on which drive generation it's paired with. On the older ATV61H and ATV71H (heavy-duty) and ATV71P (pump) drives at 4–5.5 kW, the filter knocks THDI down to 10 %. On the ATV61W (washdown) variant at the same power, it achieves 5 %. On current-generation Altivar drives — ATV630, ATV650, ATV930, ATV950 — wall-mounted at 4–5.5 kW, the filter delivers 5 % THDI. That's a meaningful difference: 5 % THDI keeps the installation compliant with the tighter G5/4 engineering recommendation, while 10 % still satisfies IEC 61000-3-4 for most industrial grids. The filter connects via screw terminals accepting 0.5 to 10 mm² wire on the main power terminals and 2.5 mm² on the control/ground terminals. It carries an IP20 rating as a stand-alone component; when mounted inside an enclosure, the enclosure can achieve IP55. Operating temperature range is 5 to 45 °C without derating; above that up to 60 °C, derate current by 3 % per °C. Above 1000 m altitude, derate 5 % per additional 1000 m. Storage in original packaging is -25 to 55 °C, transport up to 65 °C.","metaTitle":"Schneider VW3A46121 Passive Filter, 10 A, 400 V, 50 Hz","metaDescription":"Schneider VW3A46121 passive harmonic filter, 10 A input, 400 V, 50 Hz.
