Medium voltage drive for 869 kW motor loads
The ATV1200A10406060 is a Schneider Electric Altivar 1200 medium voltage AC drive rated for 869 kW motor power with 1040 kVA apparent power. It accepts a 2970-3630 V supply through a 30-pulse diode rectifier input stage, which keeps line-side harmonics low enough to meet IEEE 519 without external filtering in most installations. This drive is built for asynchronous and synchronous motors in applications where a single drive handles a large pump, fan, compressor, or conveyor — the 869 kW rating puts it squarely in medium-voltage territory, typically 3.3 kV class.
Overload profile and fault clearing
The overload withstand profile gives you two operating modes: standard overload handles 1.2× rated current for 60 seconds and 1.5× for 3 seconds; high overload pushes to 1.5× for 60 seconds and 1.85× for 3 seconds. This matters when sizing for a high-inertia load that needs extended acceleration time — the high-overload curve keeps the drive online through the start transient without tripping. Dielectric strength is 20 kV AC between earth and power terminals, with prospective line short-circuit capacity rated at 31.5 kA for 150 ms. That SCCR figure tells you the upstream protection must clear a fault within that window or the drive's internal fault withstand is exceeded.
Physical footprint and enclosure
This drive ships as a floor-standing enclosure with separate air flows for the power cell section and the control compartment. Standard efficiency dimensions are 3160 mm wide × 1400 mm deep × 2590 mm high; the high-efficiency variant runs 3460 mm wide × 1600 mm deep × 2740 mm high. The cooling fan moves 19900 m³/h (standard) or 23200 m³/h (high efficiency) — plan for that airflow path and acoustic noise at 80 dB. Product composition includes the phase-shifting transformer, 15 power cells, medium-voltage arrestors, cooling fans, and the HMI. The transformer is integrated, not external — the whole assembly arrives as one unit, which simplifies site wiring but sets the minimum floor area and lifting requirements.
I/O complement and control supply
The drive provides 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 250 Ohm impedance), 2 analogue outputs (same current range), and 6 discrete inputs expandable to 10. The control supply requires 220 V AC at 3 kVA externally; the cooling fan runs on a separate 380 V AC supply. Electrical connection uses M10 screw-type bars accepting up to 6 × 40 mm² cable per phase, entry from top or bottom.
Standards and operating envelope
CE marked and compliant with EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (thermal), EN/IEC 61800-5-1 (safety), EN/IEC 60204-11 (electrical equipment), and EN/IEC 60529 (enclosure protection). Operating altitude up to 1000 m with 0.6% current derating per additional 100 m up to 2000 m; relative humidity 0-90% standard, 0-95% optional. Vibration resistance tested at 4.9 m/s² over 10-50 Hz. The integrated EMC filter covers conducted emissions for the CE declaration — no external filter box needed for standard industrial environments.
