The VW3A46112A is a passive harmonic filter sized for one ATV610 drive powering a 75 kW / 100 hp motor on a 380–480 V three-phase supply. Its headline spec is the 10% THDI — that's the total harmonic current distortion it holds the drive's input to, which keeps the line clean enough to avoid nuisance tripping of upstream protection and to stay inside IEEE 519 limits at the point of common coupling. The filter is rated for 111 A on the input side and 160 A on the output side, so it matches the drive's full-load current without derating. Efficiency sits at 98%, meaning the 618 W of thermal losses it sheds needs ventilation clearance in the enclosure — IP20 construction means it's for cabinet mounting, not standalone outdoor use.
Integration notes
Mounts inside a cabinet — IP20, no washdown rating. The power terminals accept 50–95 mm² on /L2/L3 and '/L2'/L3', with separate 10 mm² terminals for the D1/D2/D3 damping connections and 0.5–4 mm² for the TS/TS' thermistor link. Operating ambient is -25 to 45 °C without current derating; storage range is -25 to 85 °C. The filter is wired between the line and the drive input — one filter per drive, no sharing across multiple units.
