The VW3A7265 is a line filter choke (LFC) designed as a component of the Active Front End (AFE) for Schneider's VW3A7250 active infeed converter. It's a built-in unit — no enclosure, IP00 — meant for panel integration where the cabinet provides the protection. Rated for 120 kW at 380...480 V three-phase, it carries 180 A line current at 50 °C. That's the continuous rating — no forced cooling here, it's natural convection, shedding 960 W of thermal losses. Class H insulation means it handles the heat soak without derating the winding life.
Mounting and connection — what to expect in the panel
It's a built-in assembly: 835 mm wide, 210 mm tall, 185 mm deep. That's a substantial footprint — plan for a dedicated bay in the cabinet, not a DIN-rail clip. The electrical connection is via M10 bars: two runs of 150 mm² per phase, plus a 95 mm² PE bar, torqued to 24 N·m. That's a serious bus-bar interface, not a terminal block. Natural convection cooling means you need clear air path around the choke — no stacking, no tight enclosures without ventilation planning. The 960 W of heat has to go somewhere. Vibration resistance is 1.5 mm at 3-10 Hz and 0.6 gn at 10-200 Hz per IEC 60068-2-6; shock is 7 gn for 11 ms per EN/IEC 60068-2-27. It'll survive transport and normal industrial floor vibration, but mount it on a solid backplate.
Environmental and operating limits
Operating temperature range is -10 to 45 °C, or up to 60 °C with current derating. Storage is -25 to 70 °C. Humidity tolerance is 0-95% non-condensing. Environmental class is 3K3 per EN/IEC 60721-3-3 — controlled indoor conditions, no condensation or icing.
