The Schneider VW3A46138 is a passive line filter sized for Altivar drives in the 220–500 kW / 350–700 hp range. It knocks current harmonics down to 5 % THDI across the ATV71, ATV630, and ATV930 families — the same figure whether you're running a 250 kW ATV71H or a 500 kW ATV930. That's the IEC 61000-3-12 compliance number; the filter is also listed against G5/4, IEC 61000-2-2, and IEC 61000-2-4.
Rated 433 A on the input side and 450 A on the output at 400 V +/- 10 %, 50 Hz. The 1.5 x nominal current overload for 60 s handles the inrush and acceleration peaks a drive sees. Efficiency sits at 98 %, so the 1852 W thermal loss is what you need to vent — that's real heat for the enclosure fan or cabinet airflow to clear, not a number you ignore on a panel layout. Power factor correction is load-dependent: cos phi hits 1 at 150 % line current, 0.99 at 100 %, and 0.85 at 75 %. That means the filter's reactive compensation drops off at light load — expected for a passive stage, but worth noting if your drive spends most of its time below 75 % current.
IP20 as a standalone unit; mount it in an enclosure and it reaches IP55. The power terminals accept 25–300 mm² cable on the main lugs and 2.5 mm² on the control/auxiliary terminals. Operating temperature is 5–45 °C without derating; above that, derate 3 % per °C up to 60 °C. Altitude derating starts at 1000 m, 5 % per 1000 m. 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.
