It's a built-in unit, not an add-on box, so it lands inside the panel as part of the drive system. Rated 145 kW continuous with line current 212 A at 400 V and 160 A at 480 V. Continuous output current sits at 220 A at 400 V, 203 A at 480 V — so the 480 V leg gives you slightly less current headroom but higher voltage for the same power band. ## Mounting and cooling — what fits in the cabinet The unit measures 782 mm high by 350 mm wide by 377 mm deep — that's a tall, narrow footprint. Vertical mounting only, within ±10 degrees. Forced convection cooling moves 600 m³/h through the power circuit and 145 m³/h through the control section, so the panel needs 700 cm² of free air surface for intake and exhaust. Thermal losses run 2660 W at full load — plan the cabinet cooling around that. IP00 means no ingress protection — this is a panel-mount component, not a standalone enclosure. Pollution degree 2 per EN 61800-5-1 covers normal industrial environments with non-conductive dust. ## Communication and fieldbus integration The VW3A7251 carries a communication bridge option card with one RJ45 for Modbus and a Male SUB-D 9 on RJ45 for CANopen. Both protocols are on the same connector set — you pick the fieldbus at commissioning. The AIC talks to the drive over the DC bus, not the fieldbus, so the communication ports are for configuration and monitoring. ## Lifecycle and sourcing Standards compliance covers EN/IEC 61800-5-1 for adjustable speed drives, plus environmental classes 3K3 (temperature/humidity), 3C2 (chemical), and 3S2 (mechanical) per EN/IEC 60721-3-3. Operating altitude derates 1% per 100 m above 1000 m, up to 3000 m.","metaTitle":"Schneider Electric VW3A7251 Active Infeed Converter, 145 kW","metaDescription":"Schneider Electric VW3A7251 active infeed converter, 145 kW at 400 V, 166 kW at 480 V.
