5852 kW medium-voltage drive — what the ratings mean
The ATV1200A70006666 is a Schneider Electric Altivar 1200 medium-voltage AC drive rated for 5852 kW motor power at 7000 kVA apparent power. This is a large-format drive for high-power asynchronous motors in the 3 kV class. Line current is 720 A with a 36-pulse diode rectifier bridge input, which keeps input harmonics low enough that an integrated EMC filter is standard — no external filter cabinet needed for most installations. Supply voltage limits are 2970...3630 V, so this drive lands on 3.3 kV nominal systems. The output voltage is equal to or less than the supply voltage, meaning the motor sees the same voltage class as the incoming line.
Overload profile and fault withstand
Standard overload rating holds 1.2× rated current for 60 seconds and 1.5× for 3 seconds. High overload profile steps up to 1.5× for 60 seconds and 1.85× for 3 seconds — this matters when sizing for crushers, mills, or extruders with high breakaway torque. Prospective short-circuit current withstand is 31.5 kA for 150 ms, so the drive handles a bolted fault at the input bus long enough for upstream protection to clear without the drive becoming the failure point. Dielectric strength between earth and power terminals is 20 kV AC — a safety margin that reflects the medium-voltage isolation requirements in EN/IEC 61800-5-1.
Physical footprint and cooling
The drive ships in a floor-standing enclosure with separate air flows for the power cells and control section. Dimensions are 3040 mm high by 9470 mm wide by 1600 mm deep in the standard-efficiency configuration. Cooling is forced convection moving 90000 m³/h of air. The noise level at full cooling is 80 dB — plan for hearing protection in the drive room and check the installation site for ventilation duct capacity. Operating altitude is 1000 m to 2000 m with a 0.6 % current derating per 100 m above 1000 m. Above 2000 m the derating curve continues per the datasheet; the drive is not rated for high-altitude installations without a derating calculation.
System composition and control interfaces
The ATV1200A70006666 ships as a complete system: two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, an HMI, and 18 power cells. This is not a bare drive — it is a pre-assembled drive cabinet ready for line-up installation. Control supply requires an external 220 V AC source at 3 kVA. The cooling fan runs on a separate 380 V AC supply. An optional external 220 V AC/DC control supply is available for redundancy. The drive has 4 software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ohm impedance) and 1 analogue output of the same type. Discrete inputs number 6 standard, expandable to 10. Electrical connection is via M10 screw-type bars accepting up to 6 x 40 mm² per phase, entry from top or bottom.
Compliance and lifecycle
The drive carries CE marking and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Pollution degree 2 per the last standard — suitable for controlled indoor environments with non-conductive pollution.
