The ATV1200A10706666 is a Schneider Altivar 1200 medium-voltage drive rated for 895 kW motor power at 1070 kVA apparent power, supplied from a 2970...3630 V three-phase input. That 1070 kVA figure tells you the transformer and upstream switchgear need to be sized for the full apparent power, not just the motor kW — the drive's 36-pulse diode front end draws 100 A line current at full load. The 36-pulse rectifier bridge is the key harmonic-mitigation feature: it cancels the 5th, 7th, 11th, and 13th harmonics at the input, so this drive typically meets IEEE 519 without an external filter. That saves floor space and avoids the insertion loss of a line reactor or multi-pulse transformer external to the drive. The overload profile is dual-rated: 1.2 In for 60 s (standard) or 1.5 In for 3 s (standard), and 1.5 In for 60 s or 1.85 In for 3 s under high-overload duty. The high-overload curve suits applications like crushers or extruders that need a short torque spike above rated current — the standard curve is enough for centrifugal pumps and fans.
The drive ships as a floor-standing enclosure with separate air flows for the power section and control compartment. The kit includes: 2 x plinth, phase-shifting transformer, medium-voltage arrestors, cooling fans, human-machine interface, and 18 x power cells. That is the complete drive — no external line reactor or multi-pulse transformer to source separately. Dimensions depend on the efficiency variant: standard efficiency is 3360 mm wide × 1400 mm deep × 2520 mm high; high efficiency is 3660 mm wide × 1600 mm deep × 2670 mm high. The high-efficiency variant also moves 19,800 m³/h of cooling air versus 16,500 m³/h for standard — factor that into the room ventilation design. The main power connection uses M10 screw-type bar terminals accepting up to 6 x 40 mm² per phase, with cable entry from the bottom or top. Control supply is 220 V AC at 3 kVA, with an optional 220 V AC/DC control supply; the cooling fan runs on a separate 380 V AC supply. That separate fan supply means the drive can be powered down for maintenance while the cabinet ventilation stays live.
Active production — sourcing and compliance
Dielectric strength is 20 kV AC between earth and power terminals. Prospective line short-circuit current withstand is 31.5 kA for 150 ms — the upstream breaker must be coordinated to clear within that window to protect the drive's input diodes. Operating altitude derating applies above 1000 m: 0.6 % current derating per 100 m up to 2000 m. Pollution degree 2 per EN/IEC 61800-5-1 means the drive is rated for normal industrial atmospheres with only non-conductive dust — not for conductive粉尘 or heavy chemical exposure.
