539 kW active front end — what it does in the drive line
The VW3A7287: This is a low-harmonics, energy-regeneration component: it pulls sinusoidal current from the line and pushes braking energy back onto the grid instead of burning it in a resistor bank. The 60 s overload capability is 1.20× nominal current; the 2 s peak is 1.35×.
Obsolete — sourcing reality for this AIC
Schneider lists this part as obsolete (mature lifecycle stage). The unit is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. Expect to provide the target quantity and any preferred date window; pricing and availability are confirmed at quote time, not before.
Physical footprint and panel integration
The built-in unit measures 1100 mm wide × 1150 mm high × 377 mm deep — that is a substantial cabinet footprint. The IP00 enclosure means it is not touch-safe; it must be installed inside a locked or tooled-accessible electrical enclosure with appropriate guarding. Forced convection cooling moves 2400 m³/h through the power circuit and 660 m³/h through the control circuit. The required free air flow surface area is 2000 cm². Thermal losses at full load are 8920 W — that heat has to be exhausted from the cabinet, so factor the ventilation or air-conditioning capacity into the panel design.
Environmental and compliance envelope
Ambient temperature range is -10 to 45 °C without derating; above 45 °C derate 2 % per °C up to 60 °C. Storage temperature is -25 to 70 °C. Vibration resistance per EN/IEC 60068-2-6: 1.5 mm displacement at 3–10 Hz, 0.6 gn at 10–200 Hz. Shock resistance is 4 gn for 11 ms per EN/IEC 60721-3-3. Environmental classification is 3K3 (temperature/humidity), 3C2 (chemical), 3S2 (mechanical) per the same standard.
