The ATV1200A81005555 is a Schneider Electric Altivar 1200 series AC drive rated for 6772 kW motor power with 8100 kVA apparent power, fed from a 2970-3630 V supply. It drives both synchronous and asynchronous motors — that covers the main motor types you'll find on large pumps, compressors, and conveyors in process plants. The input stage uses a 30-pulse diode rectifier bridge, which keeps line harmonics low enough to skip a separate filter on most utility feeds. Prospective short-circuit current withstand is 31.5 kA for 150 ms — that's the fault-clearing capability the upstream protection needs to coordinate with.
Overload profiles and duty cycle
Standard overload rating: 1.2× rated current for 60 seconds, or 1.5× for 3 seconds. High overload profile pushes to 1.5× for 60 seconds and 1.85× for 3 seconds. That high-overload headroom matters when sizing for a loaded conveyor start or a crusher that sees momentary torque spikes. The drive's output voltage is equal to or less than the supply voltage — no step-up inside the cabinet. That means the motor winding insulation only needs to handle the line voltage, not a boosted DC bus.
Physical build and installation constraints
This is a floor-standing enclosure with separate airflows for the power cells and control section. Dimensions: 1700 mm deep, 8970 mm wide, 3040 mm high — that's a large footprint requiring a dedicated equipment room with overhead lifting access. Cooling is forced convection moving 90,000 m³/h of air. The drive ships as a complete assembly: 2 plinths, phase-shifting transformer, medium-voltage arrestors, cooling fans, HMI, and 15 power cells. Power connection uses M10 screw-type bars accepting up to 6×40 mm² cable per phase, entry from top or bottom.
Control supply and I/O complement
Control power comes from an external 220 V AC supply rated 3 kVA, with an optional 220 V AC/DC external supply. The cooling fans run on a separate 380 V AC supply — that separation means the drive can keep the cabinet ventilated even if the control supply drops. Standard I/O: 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 250 Ω impedance), 2 analogue outputs (same current ranges), and 6 discrete inputs expandable to 10. The analogue loop impedance matches standard 2-wire transmitter outputs — no external burden resistor needed.
Standards, approvals, and environmental limits
CE marked. Complies with EN/IEC 60204-11 (electrical equipment of machines), EN/IEC 60529 (enclosure protection), EN/IEC 61800-3 (EMC for drive systems), EN/IEC 61800-4 (drive specifications), and EN/IEC 61800-5-1 (electrical safety for adjustable-speed drives). Pollution degree 2 per EN/IEC 61800-5-1 — suitable for clean industrial environments without conductive dust. Operating altitude: 1000-2000 m with 0.6 % current derating per 100 m above 1000 m. Relative humidity 0-90 % (0-95 % optional). Operating position vertical ±10°. Vibration resistance 4.9 m/s² at 10-50 Hz. Noise level 80 dB — hearing protection required near the cabinet.
This is a large medium-voltage drive built to order; availability and pricing are confirmed at RFQ against the specific BOM configuration. No direct drop-in alternative exists in the Altivar 1200 family — the power rating and voltage class define the frame size.
