430 kW active front end for regenerative drives
The VW3A7275: Continuous output current is 386 A across the full voltage range, with overload capability of 1.20× nominal for 60 s and 1.35× for 2 s — enough to handle motor acceleration and transient loads without tripping.
Installation constraints — IP00, forced air, floor-standing
This is a built-in unit with IP00 protection — no enclosure, so it must be installed inside a panel or cabinet that provides the environmental seal. The forced-convection cooling system moves 200 m³/h for the control circuit and 1200 m³/h for the power circuit, requiring a minimum 1000 cm² air-flow surface on the cabinet. Physical footprint is 585 mm wide × 377 mm deep × 1190 mm high. Mount vertically within ±10° of plumb. Operating altitude derates current 1% per 100 m above 1000 m; ambient temperature range is -10 to 45 °C, with derating of 2% per °C up to 60 °C.
Communication and compliance
A communication bridge option card provides dual-protocol connectivity: one RJ45 for Modbus and a SUB-D 9 on RJ45 adapter for CANopen. The unit carries EN/IEC 61800-5-1 safety standard compliance, pollution degree 2, and environmental classification 3K3/3C2/3S2 per EN/IEC 60721-3-3. Vibration resistance is 1.5 mm at 3-10 Hz and 0.6 gn at 10-200 Hz per EN/IEC 60068-2-6; shock resistance is 4 gn for 11 ms per EN/IEC 60721-3-3.
Lifecycle and sourcing — obsolete, quoted to order
Schneider Electric lists the VW3A7275 as obsolete (mature stage). This part is available through independent distribution channels; quantities and pricing are confirmed at RFQ against the specific BOM line.
