What this AIC does and where it fits
The VW3A7270: Rated for 145 kW continuous output, with 130 A continuous output current at 500 V, 600 V, or 690 V. The overload capability is 1.2× nominal for 60 s and 1.35× for 2 s — enough to ride through a motor acceleration or a momentary load spike.
Schneider lists this part as obsolete (mature lifecycle stage). The VW3A7270 is sourced through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that needs this exact unit, the supply posture is quoted-to-order.
Standards and environmental rating
Designed to EN/IEC 61800-5-1 (adjustable speed drive safety) with pollution degree 2. Environmental classification is 3K3 (temperature/humidity), 3C2 (chemical), and 3S2 (mechanical) per EN/IEC 60721-3-3. Operates at -10 to 45 °C ambient without derating; above 45 °C up to 60 °C, derate current 2 % per °C. Altitude derating begins above 1000 m at 1 % per 100 m. IP00 — requires enclosure mounting with adequate airflow (700 cm² free area, 600 m³/h for power circuit).
Communication and integration
Built-in Modbus and CANopen via dual RJ45 ports (one dedicated RJ45 for Modbus, one SUB-D 9 to RJ45 adapter for CANopen). The option card slot accepts a communication bridge for fieldbus expansion. Physical footprint: 1190 mm high × 330 mm wide × 377 mm deep. Mounts as a built-in unit in a vertical orientation (±10°). Forced convection cooling — the 2200 W thermal loss must be ducted out of the enclosure.
