Medium-voltage drive for large motor loads
The Schneider Electric ATV1200A14504242 is an Altivar 1200 series medium-voltage AC drive rated for 1212 kW motor power with 1450 kVA apparent power, designed for large induction and synchronous motors in heavy industrial applications. It accepts a supply voltage of 2970...3630 V AC through a 24-pulse diode rectifier bridge, which reduces line-side harmonics below IEEE 519 thresholds without external filters.
Overload profile and fault handling
Standard overload capability is 1.2× rated current for 60 seconds and 1.5× for 3 seconds; high overload mode extends the 1.5× window to 60 seconds and allows 1.85× for 3 seconds — this matters for crushers, conveyors, and mills that see short-duration peak torque events. The drive withstands a prospective line short-circuit current of 31.5 kA for 150 ms, and dielectric strength between earth and power terminals is tested at 20 kV AC. Ground fault protection is integrated on the drive side, and the unit is pollution degree 2 rated per EN/IEC 61800-5-1.
Physical footprint and cooling
The drive ships in a floor-standing enclosure with separate air flows for power and control sections. Standard efficiency variant measures 1400 mm deep × 4060 mm wide × 2670 mm high; the high efficiency version is 1600 mm deep × 4360 mm wide at the same height. Forced convection cooling moves 16500 m³/h (standard) or 19900 m³/h (high efficiency) of air, with an 80 dB noise level — plan for hearing protection zones near the installation. Operating altitude range is 1000...2000 m with 0.6 % current derating per 100 m above 1000 m; the unit must be mounted vertically within ±10 degrees.
Compliance and lifecycle
The ATV1200A14504242 carries CE marking and conforms to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Lifecycle status is current production — quoted to order against the BOM quantity through independent distribution channels.
