6897 kW drive, floor-standing — what it means on the line
The ATV1200A82506666 is a medium-voltage drive from the Altivar 1200 family, rated for 6897 kW motor power and 8250 kVA apparent power. That puts it squarely in the large-motor class — think mainline conveyors, crushers, large pumps or compressors in mining, cement, or oil-and-gas installations. Supply voltage range is 2970…3630 V, fed through a 36-pulse diode rectifier bridge. The 36-pulse topology cancels the 5th, 7th, 11th, and 13th harmonics at the input, which means you can often skip a dedicated harmonic filter at the point of common coupling — that saves panel space and transformer derating.
Physical footprint and installation constraints
This is a floor-standing enclosure, not a wall-mount. Dimensions are 3040 mm high, 9770 mm wide, and 1700 mm deep — so you need a dedicated drive room with a reinforced floor and a crane or forklift path for positioning. The enclosure has separate air flows for power and control sections, which keeps the electronics cooler and reduces dust ingress. Cooling is forced convection pulling 100,000 m³/h of air — that's substantial. The room's HVAC and louvers need to handle that airflow without recirculating hot exhaust. Operating altitude derating starts at 1000 m: 0.6 % current reduction per 100 m above that.
Overload duty and auxiliary supply architecture
The drive supports two overload profiles. Standard overload: 1.2× In for 60 s, 1.5× In for 3 s. High overload: 1.5× In for 60 s, 1.85× In for 3 s. Pick the profile that matches your load cycle — high overload covers crusher start-ups or extruder breakaway torque without oversizing the drive frame. Control electronics need an external 220 V AC supply rated at 3 kVA. The cooling fans run on a separate 380 V AC supply (also external). There's an optional 220 V AC/DC control supply. This split architecture means the control section stays live even if the main power is off — useful for pre-charge sequencing and diagnostics before the main contactor closes.
Compliance is solid: CE marked, designed to EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (adjustable speed drives), and EN/IEC 61800-5-1 (electrical safety). Pollution degree 2 per the same safety standard, overvoltage category II. The integrated EMC filter means you don't need an external input filter for most installations.
