What this VFD is and what it drives
The Schneider Electric ATV1200A85001010 is a medium-voltage AC drive from the Altivar 1200 family, designed for large asynchronous motors up to 7106 kW. It delivers 8500 kVA apparent power from a 2970...3630 V supply, using a 48-pulse diode rectifier bridge input topology that keeps line-side harmonics low enough to often skip an external filter.
Sizing the overload and fault handling
The drive handles 1.2× In for 60 s under standard overload, and 1.5× In for 3 s; for high-overload profiles it sustains 1.5× In for 60 s and 1.85× In for 3 s — match the duty cycle to your load profile before freezing the BOM. Prospective line short-circuit current is rated at 31.5 kA for 150 ms, and the drive includes ground-fault protection on the output side. Dielectric strength between earth and power terminals is 28 kV AC — this is a medium-voltage drive, not a 480 V unit; the supply voltage limits (2970...3630 V) confirm the class.
Physical footprint and installation constraints
The drive ships in a floor-standing enclosure measuring 1700 mm deep, 9370 mm wide, and 3040 mm high — this is a multi-cabinet lineup, not a wall-mount unit. Plan for a dedicated electrical room with overhead bus or cable trench access. Cooling is forced convection requiring 110000 m³/h of air volume — the room HVAC must handle this rejection, and the separate air-flow paths keep power-cell heat from recirculating into the control section. Noise level is 80 dB — hearing protection zones apply near the enclosure during operation. Operating altitude derating starts at 1000 m: 0.6 % per 100 m above that. The drive must be mounted vertical ±10° and the ambient relative humidity kept between 0...90 % (0...95 % with optional treatment).
Control supply and I/O architecture
The control section needs an external 220 V AC supply at 3 kVA (or optional 220 V AC/DC); the cooling fans run on a separate 380 V AC supply. Electrical isolation between power and control circuits is maintained. Standard I/O includes 4 software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ω impedance), 1 analogue output of the same type, 6 discrete inputs (expandable to 10), and a built-in EMC filter. Main power connection uses M10 screw-type bars accepting up to 6 × 40 mm² cable per phase, entry from top or bottom.
Standards compliance and lifecycle status
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. Lifecycle stage is current production — this is an active catalogue item, not a phase-out or legacy part. The ATV1200 series remains in Schneider's standard portfolio for medium-voltage drives.
