Passive filter for Altivar drives — obsolete, sourced to order
The Schneider Electric VW3A4601 is a passive filter designed to reduce current harmonics on Altivar variable speed drives. It is rated at 6 A continuous current and accepts a 400 V +/- 10 % three-phase supply. This part is now classified as obsolete by the manufacturer.
THDI performance by drive model
The harmonic reduction performance depends on which Altivar drive it is paired with. For the ATV61W series (0.75 kW to 3 kW), the filter achieves a THDI of 10 %. For the ATV61H, ATV71H, ATV71P, and ATV71W series in the same power range, the THDI is 16 %. This means the filter delivers better harmonic suppression on the compact 'W' frame drives than on the standard 'H' or 'P' frame units. One filter per drive is required.
Electrical and environmental ratings
The filter operates at 98 % efficiency and can handle up to 1.5 times the nominal current without damage. Power factor correction is inherent — cos phi reaches 0.99 at 100 % line current and 0.85 at 75 % load. The connection terminal accepts up to 16 mm² conductors. Ambient temperature range is 5 °C to 40 °C without derating; above 40 °C up to 55 °C, derate current by 3 % per °C. Storage temperature spans -25 °C to 55 °C. At altitudes above 1000 m, derate current 5 % per additional 1000 m up to 4000 m. Relative humidity tolerance is 5 % to 85 % non-condensing.
