What the ATV1200A41203333 is and what it handles
The Schneider Electric ATV1200A41203333 is an Altivar 1200 series medium-voltage AC drive rated for 3444 kW motor power, designed to run both asynchronous and synchronous motors from a 2970...3630 V supply. It draws 720 A line current and delivers 4120 kVA apparent power, with an 18-pulse diode rectifier front end that reduces line harmonics compared to a 6- or 12-pulse topology.
Physical scale and installation constraints
This is a large, floor-standing drive: 2740 mm high, 5870 mm wide, and 1700 mm deep in its standard-efficiency configuration, with separate air flows for the power section and control compartment. The enclosure is grey (RAL 7032) and must be installed vertically within ±10°; operating altitude above 1000 m requires derating the output current by 0.6 % per 100 m up to 2000 m. Forced-convection cooling moves 60000 m³/h of air at standard efficiency — plan the room's ventilation capacity around that airflow, not just the drive footprint.
Overload capability and protection
The drive offers two overload profiles: standard overload handles 1.2× In for 60 s or 1.5× In for 3 s; high overload handles 1.5× In for 60 s or 1.85× In for 3 s. Match the profile to the load duty cycle — a crusher or centrifuge starting into a loaded condition needs the high-overload setting. Built-in ground-fault protection covers the drive output, and the prospective line short-circuit current rating is 31.5 kA for 150 ms — the upstream protection must coordinate within that window. Dielectric strength is tested at 10 kV AC between earth and power terminals, and electrical isolation between power and control circuits is standard.
Control wiring and I/O complement
The drive includes 4 software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ω impedance, 24 V max) and 1 analogue output of the same type, plus 6 discrete inputs expandable to 10 with an optional module. Control power comes from an external 220 V AC supply (3 kVA) or an optional 220 V AC/DC source; the internal cooling fan runs on 380 V AC, also available as an external option.
Standards, compliance, and lifecycle
CE marked and designed to 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 EN/IEC 61800-5-1, overvoltage category II.
