What the 4473 kW rating and 36-pulse input mean for your installation
The ATV1200A60006363: This Altivar 1200 is a medium-voltage drive rated for 4473 kW motor power at a supply voltage of 2970 to 3630 V AC — it drives large induction motors in the 4–5 MW class, not the 480 V low-voltage world the category trail might suggest. The 36-pulse diode rectifier front end draws line current of 490 A and keeps input harmonics low enough that an external harmonic filter is typically unnecessary for IEEE 519 compliance — that is one less cabinet and one less SKU to spec. Apparent power is 5350 kVA, so the upstream transformer and switchgear must be sized for that full-load kVA plus the 1.2× overload for 60 seconds (standard duty) or 1.5× for 60 seconds (high overload profile).
Physical footprint — this is a walk-in cabinet, not a panel-mount drive
The ATV1200A60006363 ships as a floor-standing enclosure with separate air flows for the transformer and power cells. Standard-efficiency dimensions: 2820 mm high × 6670 mm wide × 1800 mm deep; the high-efficiency variant adds height (3040 mm) and width (6970 mm). Operating position is vertical ±10 degrees; altitude derating begins at 1000 m at 0.6 % per 100 m above that. Pollution degree 2 per EN/IEC 61800-5-1 means the enclosure location should be clean, non-conductive dust environment.
Standards, isolation, and protection — what the compliance marks cover
CE marked, with design compliance to EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (harmonics), EN/IEC 61800-5-1 (safety), EN/IEC 60204-11 (machinery), and EN/IEC 60529 (enclosure protection). Electrical isolation between power and control circuits is standard. Dielectric strength is 20 kV AC between earth and power terminals — appropriate for the 3.3 kV class input voltage. Overvoltage category II per EN/IEC 61800-5-1. Ground fault protection is integral to the drive. Prospective line short-circuit current rating is 31.5 kA for 150 ms — coordinate upstream protection to clear within that window.
What is inside the cabinet — transformer, power cells, HMI
The drive comprises two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 18 power cells. The 36-pulse topology comes from the transformer's phase shift across the cells. Control supply is 220 V AC at 3 kVA external; cooling fan supply is 380 V AC internal. An optional external 220 V AC/DC control supply and external 380 V AC fan supply are available. I/O complement: 4 software-configurable analogue inputs (0–20 mA / 4–20 mA, 250 Ω impedance), 1 analogue output (same range), and 6 discrete inputs standard (10 optional).
