Medium-voltage drive for large asynchronous motors
The Schneider Electric ATV1200A28006666 is an Altivar 1200 series medium-voltage AC drive rated for 2341 kW motor power from a 2970-3630 V supply. It is designed for asynchronous motor control in applications where a 36-pulse diode rectifier bridge is specified for line-side harmonic mitigation. The drive draws 280 A line current at 2800 kVA apparent power, with a prospective line short-circuit current withstand of 31.5 kA for 150 ms. Overload capability is 1.2× In for 60 s (standard) or 1.5× In for 3 s (standard), with a high-overload profile of 1.5× In for 60 s and 1.85× In for 3 s.
Physical footprint and site integration
The drive ships in a floor-standing enclosure with separate air flows for power and control sections. Standard-efficiency configuration measures 5170 mm wide × 2740 mm high × 1700 mm deep; the high-efficiency variant is wider at 5470 mm. Operating position is vertical within ±10 degrees. Forced convection cooling moves 43200 m³/h of air, with a noise level of 80 dB. The enclosure colour is grey (RAL 7032). Supply for the control section is 220 V AC at 3 kVA; the cooling fan runs on 380 V AC. The product composition includes two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 18 power cells. Electrical connection uses M10 bar-type screw terminals with clamping capacity for 6 × 40 mm² conductors per phase, entry from bottom or top.
Standards compliance and environmental ratings
The ATV1200A28006666 carries CE marking and is designed to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Dielectric strength between earth and power terminals is 20 kV AC. Operating altitude is 1000-2000 m with 0.6 % current derating per 100 m above 1000 m. Relative humidity range is 0-90 % (0-95 % optional). Vibration resistance is 4.9 m/s² at 10-50 Hz.
