Its headline spec is a THDI of 5% at full load — that means it knocks line-current harmonics down to 5% of fundamental, which keeps the drive from polluting the plant distribution and avoids oversizing transformers or upstream breakers. Rated 325 A continuous at 400 V +/- 10%, 3-phase, 50 Hz. The 1.5 x nominal current peak rating handles motor inrush and short overloads without saturating the core. Efficiency is 98%, so you lose about 2% of the drive's input power as heat in the filter — factor that into the enclosure ventilation. Class F insulation means the winding can run hot (155 °C) without degrading, typical for this duty. Operating ambient is 5...40 °C at full current; above 40 °C derate 3% per °C up to 55 °C. Above 1000 m altitude derate 5% per 1000 m. IP20 enclosure — panel-mount only, no washdown. ## Integration note Two filters per drive for ATV61HC40N4 and ATV71HC40N4 — the 325 A rating is per filter, so a pair handles the full 355 kW drive input. Bare-wire connection, 16.5 mm diameter. Mount it between the line supply and the drive input; the filter's passive LC network does not need a control signal. Relative humidity 5...85% non-condensing. Storage range -25...55 °C.","metaTitle":"Schneider VW3A4639 Passive Filter, 325 A, 400 V, THDI 5%","metaDescription":"VW3A4639 passive harmonic filter for Altivar ATV61/ATV71 drives.

That means line-current harmonics are suppressed to 5% of the fundamental at full load."},{"question":"What is the power factor correction profile of VW3A4639?","answer":"The filter's cos phi is 1 at 150% of line current, 0.99 at 100% of line current, and 0.85 at 75% of line current — so it maintains near-unity power factor across the load range, dropping only at light load."},{"question":"Where can I buy VW3A4639 and get current pricing?","answer":"The VW3A4639 is sourced to order through independent distribution.
