46 A EMC input filter for ATV61/ATV71 drives
The VW3A4404 is an EMC input filter designed for Schneider Electric Altivar ATV61 and ATV71 variable speed drives, handling 46 A on a three-phase 380-500 V supply. It conforms to IEC 61800-3 for adjustable speed drive EMC emissions, with a maximum earth leakage current of 14 mA at 400 V 50 Hz. Thermal losses run 13 W for the 380-480 V range and 19 W for 200-240 V — factor this into enclosure ventilation when mounting in a panel.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible drop-in replacement exists from the original manufacturer; a functional equivalent would require verifying the drive compatibility and mounting footprint.
Mounting and environmental limits
Rated IP20 with IP41 on the upper part, suitable for clean indoor panel environments. Terminal accepts up to 16 mm² / AWG 4 wire with a 2 N·m tightening torque. Operates from -10 to 50 °C ambient and stores from -40 to 65 °C. Above 1000 m altitude, derate current 1 % per 100 m up to 3000 m. Withstands 15 gn shock for 11 ms per IEC 60068-2-27 and 1 gn vibration at 13-150 Hz per IEC 60068-2-6.
