940 kVA at 3 kV — what the rating means for the load
The ATV1200A9406060 is rated for 940 kVA apparent power and 786 kW motor power, fed from a 2970-3630 V supply — this is a medium-voltage drive sized for large induction or synchronous motors in the 800 kW class. The 30-pulse diode rectifier bridge at the input keeps line-side harmonics low enough to skip a separate filter in most utility grids — the integrated EMC filter handles the drive-side emissions. Overload capability is 1.2× rated current for 60 seconds standard duty, or 1.5× for 3 seconds; high-overload profile pushes to 1.5× for 60 seconds and 1.85× for 3 seconds — match this to your load cycle before committing the BOM line.
Floor-standing enclosure — physical integration constraints
This drive ships in a floor-standing enclosure with separate air flows — the standard-efficiency variant measures 2860 mm wide × 2590 mm high × 1400 mm deep; the high-efficiency variant is wider at 3460 mm and taller at 2740 mm, with depth increasing to 1500 mm (-). Forced-convection cooling moves 16600 m³/h on the standard build and 23200 m³/h on the high-efficiency build — the room's ventilation must handle that airflow without recirculating hot exhaust into the intake. Operating altitude derates current 0.6 % per 100 m above 1000 m; the drive must sit vertical within ±10°.
No pin-compatible alternative exists in the Altivar 1200 family — the footprint and voltage class are unique to this order code.
