The Schneider Electric VW3A7268 is a line filter choke (LFC) designed as a component of the Active Front End (AFE) system. It is paired with one of the compatible active infeed converters: VW3A7270, VW3A7271, or VW3A7272. Rated for 185 A line current at 50 °C on a 500...690 VAC three-phase network, it handles the input filtering duty for a 220 kW AFE installation. The 1230 W thermal losses are dissipated through natural convection — no fan, so panel airflow around the unit matters. At 835 mm wide, 295 mm tall, and 210 mm deep, this is a substantial built-in unit, not a DIN-rail component. The IP00 rating means it requires enclosure protection in the final installation — it is not touch-safe on its own.
Above 45 °C, the operating range extends to 60 °C with current derating. Class H insulation and 3K3 environmental classification per EN/IEC 60721-3-3 suit the thermal and humidity profile inside a ventilated industrial enclosure. Mechanical robustness is specified: 7 gn shock for 11 ms per EN/IEC 60068-2-27, and vibration resistance of 1.5 mm at 3-10 Hz and 0.6 gn at 10-200 Hz per IEC 60068-2-6. These figures matter if the panel is mounted on a machine frame or near rotating equipment.
Integration notes
Electrical connection is via M10 bars: two bars accepting up to 2 x 150 mm² cable each, plus a PE bar for 95 mm². Torque to 24 N.m on all connections. The bar layout and the 210 mm depth need to be accounted for in the enclosure layout — allow bending radius for the cable entries. Operating altitude range is 1000 to 2400 m with a 1 % current derating per 100 m above 1000 m. For installations above 2400 m, the manufacturer's guidance would apply — not covered in this listing.
