Medium-voltage drive for large asynchronous motors
The Schneider Electric ATV1200A20606666 is an Altivar 1200 series medium-voltage AC drive rated for 1722 kW motor output, designed for large asynchronous motors in heavy industrial applications. It accepts a 2970 to 3630 V supply via a 36-pulse diode rectifier bridge, which inherently reduces line-side harmonics without external filters — a key advantage for plants with strict power-quality requirements. The drive is assembled in a floor-standing enclosure with separate airflows for the power section and control compartment, keeping the electronics away from the heat of the main circuit.
The 1722 kW motor power rating is the continuous output at the drive's nominal voltage range — this is the number to match against your motor nameplate, not the apparent power rating. Apparent power is 2060 kVA, and line current is 200 A at the input — these drive the sizing of upstream transformers, cables, and the main disconnect. Overload capability is defined in two profiles: standard overload allows 1.2× rated current for 60 seconds, while high overload allows 1.5× for 60 seconds — choose the profile that matches your load cycle (conveyor vs crusher). Dielectric strength is tested at 20 kV AC between earth and power terminals — this confirms the MV isolation barrier is intact for a 3.3 kV class system.
Installation and integration constraints
Physical footprint: the enclosure is 2670 mm tall, with width ranging from 5170 mm (standard efficiency) to 5470 mm (high efficiency), and depth from 1600 mm to 1700 mm — plan for a dedicated electrical room with crane access. The drive requires external control power at 220 V AC, 3 kVA, and internal cooling fans supplied at 380 V AC — these auxiliary supplies must be factored into the panel design. Operating altitude above 1000 m requires current derating at 0.6% per 100 m; at 2000 m the available output current is roughly 94% of the sea-level rating. The 36-pulse input configuration draws a line current of 200 A and is rated for a prospective short-circuit current of 31.5 kA for 150 ms — coordinate upstream protection accordingly.
CE marked and compliant with EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (thermal), and EN/IEC 61800-5-1 (safety) — covers the key standards for industrial drive installations in Europe and most global markets. Pollution degree 2 per EN/IEC 61800-5-1 means the drive is rated for a normal industrial environment with only non-conductive contamination — not for wet or conductive dust areas without additional enclosure protection.
