What this drive handles and where it fits
The ATV1200A6603333 is a medium-voltage Altivar 1200 drive rated for 552 kW motor power at 660 kVA apparent power, accepting a supply range of 2970...3630 V. It drives both synchronous and asynchronous motors — common for large pumps, fans, compressors, and conveyors in process plants, water treatment, and mining. The 18-pulse diode rectifier bridge on the input side draws 135 A line current and keeps harmonic distortion low enough to meet IEEE 519 without external filters in most installations. Integrated EMC filter is standard.
Overload profile and fault handling
Standard overload rating holds 1.2× In for 60 s and 1.5× In for 3 s; high overload pushes to 1.5× In for 60 s and 1.85× In for 3 s. This gives headroom for starting high-inertia loads or clearing transient overloads without tripping. The drive withstands a prospective line short-circuit current of 31.5 kA for 150 ms — enough to coordinate with upstream MV switchgear on most distribution networks. Ground-fault protection is built into the drive.
Cooling, enclosure, and installation constraints
The drive ships in a floor-standing enclosure with separate airflows for the transformer and power cells. Forced convection cooling moves 9900 m³/h (standard efficiency) or 13 200 m³/h (high efficiency). Noise level is 80 dB — plan for hearing protection if the drive is in a manned area. Dimensions: 2760 mm wide (3060 mm high-efficiency), 2520 mm tall (2670 mm high-efficiency), 1400 mm deep (1500 mm high-efficiency). Pollution degree 2 per EN/IEC 61800-5-1.
Auxiliary supplies and control wiring
The control electronics require an external 220 V AC supply at 3 kVA; the cooling fan runs on 380 V AC internal supply. Optional external supplies for both are available. Electrical isolation between power and control circuits is standard. Six discrete inputs (10 optional) and four software-configurable analogue inputs (0...20 mA / 4...20 mA, 250 Ω impedance) handle most process signals. One analogue output (same current range) is provided. Dielectric strength between earth and power terminals is 10 kV AC.
