860 kVA, 719 kW medium-voltage drive — active production
The ATV1200A8603333: The 18-pulse diode rectifier input stage draws 150 A line current and delivers a clean input waveform that meets EN/IEC 61800-3 EMC limits with the integrated filter. Prospective line short-circuit current is 31.5 kA for 150 ms — the drive's internal protection and upstream coordination must handle that fault level.
Overload profile and motor compatibility
Standard overload capability is 1.2× rated current for 60 seconds and 1.5× for 3 seconds; the high-overload profile steps to 1.5× for 60 seconds and 1.85× for 3 seconds. This dual rating lets the drive handle both constant-torque conveyors and variable-torque pumps without oversizing the drive frame. The drive is designed for both synchronous and asynchronous motors, with a speed range of 20–100 %. Output voltage is limited to the supply voltage level, so motor winding insulation must be rated for the full 3.3 kV bus.
Physical footprint and installation constraints
The floor-standing enclosure measures 2760 mm wide × 2590 mm high × 1400 mm deep in the standard-efficiency configuration; the high-efficiency variant adds width to 3360 mm and height to 2740 mm, with depth increasing to 1500 mm. Cooling air volume is 16,600 m³/h (standard) or 23,200 m³/h (high efficiency), requiring a dedicated ventilation path in the substation or motor control centre room. The drive assembly includes two plinths, a phase-shifting transformer, nine power cells, medium-voltage arrestors, cooling fans, and an HMI. Separate air flows for power and control sections keep the electronics compartment within the 0–90 % humidity envelope (0–95 % optional). Operating altitude derating starts at 1000 m at 0.6 % per 100 m.
Compliance and sourcing posture
CE marked, with standards compliance 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 and overvoltage category II. Dielectric strength is 10 kV AC between earth and power terminals. Electrical isolation between power and control circuits is standard. Sourced to order against the BOM quantity through independent distribution. No pin-compatible alternative exists within the Altivar 1200 family — the ATV1200A8603333 is a specific voltage and power configuration.
