What it takes to drive a 2.4 MW motor
The ATV1200A29106060 is a medium-voltage drive from the Altivar 1200 family, rated for 2433 kW motor power at an apparent power of 2910 kVA. It accepts a supply voltage between 2970 and 3630 V and uses a 30-pulse diode rectifier bridge on the input — that pulse count keeps line-side harmonics low enough to avoid a separate filter in most installations.
The drive supports two overload profiles: standard overload handles 1.2 × In for 60 seconds and 1.5 × In for 3 seconds; high overload handles 1.5 × In for 60 seconds and 1.85 × In for 3 seconds. Pick the standard profile for centrifugal loads (pumps, fans) where the overload event is short; go with the high-overload curve for extruders, crushers, or conveyors that need a longer torque punch during start-up or jam recovery.
Physical footprint and installation constraints
This is a floor-standing enclosure with separate air flows for power and control sections. Standard-efficiency build measures 4660 mm wide × 2820 mm high × 1600 mm deep; the high-efficiency variant is wider (4960 mm) and deeper (1700 mm). Plan for a 43200 m³/h cooling air volume — that is forced convection, so the room ventilation and ducting must handle that flow without back-pressure on the fan intakes.
Line fault handling and altitude derating
The drive is rated for a prospective line short-circuit current (Isc) of 31.5 kA for 150 ms — that is the fault level the input section can withstand without damage. Above 1000 m operating altitude, derate the output current by 0.6 % per 100 m up to 2000 m. The dielectric strength between earth and power terminals is 20 kV AC, and pollution degree 2 per EN/IEC 61800-5-1 applies, so the enclosure is suited for clean industrial environments.
Standards and compliance package
CE marked and designed to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. The integrated EMC filter covers conducted emissions for the drive's power range. Electrical isolation between power and control circuits is standard. The enclosure colour is grey RAL 7032.
