Medium-voltage drive for 3.5 MW motor loads
The ATV1200A42606060 is a Schneider Electric Altivar 1200 medium-voltage variable speed drive rated for 3561 kW motor power at 4260 kVA apparent power, with a supply voltage range of 2970 to 3630 V. This is a large-format drive — the floor-standing enclosure measures 6070 mm wide by 1700 mm deep by 2740 mm high in standard efficiency configuration, or 6370 mm wide by 1800 mm deep by 3040 mm high for the high efficiency variant. The input stage uses a 30-pulse diode rectifier bridge, which inherently cancels the 5th, 7th, 11th, 13th, 17th, and 19th harmonics — meeting IEEE 519 without external filters for most installations. An integrated EMC filter is included.
The 3561 kW motor power rating at 4260 kVA apparent power tells you this drive handles a 3.3 kV induction or synchronous motor in the 3.5 MW class — typical for large pumps, compressors, conveyors, or mill drives in mining, cement, oil & gas, and water/wastewater. The 410 A line current at the 2970-3630 V supply gives the full-load input draw. Overload capability is defined per the drive's duty: 1.2× rated current for 60 seconds (standard overload) or 1.5× for 60 seconds (high overload), with short-duration peaks of 1.5× for 3 s (standard) and 1.85× for 3 s (high). This matches the IEC 61800-4 drive profile for heavy industrial loads that need starting torque or intermittent overloads. The 30-pulse rectifier topology means the drive draws near-sinusoidal line current — the 24-pulse equivalent already meets IEEE 519 at the point of common coupling for most sites, and the 30-pulse configuration adds margin. This avoids the cost and footprint of external harmonic filters.
Physical integration and cooling
This is a floor-standing enclosure with separate air flows for the power section and control compartment — the forced-convection cooling moves 46,500 m³/h of air through the cabinet. The operating position is vertical within ±10 degrees. The drive composition includes 15 power cells, a phase-shifting transformer, medium-voltage arrestors, cooling fans, and a human-machine interface. Electrical connection is via M10 bar-type terminals accepting 6 × 40 mm² conductors per phase, with cable entry from the top or bottom. Operating altitude is 1000 to 2000 m with 0.6% current derating per 100 m above 1000 m. Ambient relative humidity range is 0-90% (0-95% optional). Pollution degree 2 per EN/IEC 61800-5-1 applies — suitable for typical industrial electrical rooms with non-conductive pollution.
Control I/O and compliance
The drive offers 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 24 V max, 250 Ω impedance) and 1 analogue output of the same type. Discrete inputs number 6 standard, expandable to 10. External control supply is 220 V AC at 3 kVA, with an optional 220 V AC/DC supply; the cooling fan runs on a separate 380 V AC supply. Electrical isolation between power and control circuits is provided. Dielectric strength is tested at 20 kV AC between earth and power terminals. The drive is CE marked and complies with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1.
Sourced through authorized distribution channels. No direct pin-compatible alternative exists within the Altivar 1200 family — the order code encodes the specific power rating, supply voltage, and enclosure configuration.
