What the 30-pulse input and 3.3 kV rail mean for the installation
The ATV1200A31306060: The 30-pulse diode rectifier bridge is the key harmonic-mitigation feature — it effectively cancels the 5th, 7th, 11th, and 13th harmonics at the input, so the drive meets IEEE 519 without a separate filter bank. The supply voltage limits are 2970...3630 V, which covers the nominal 3.3 kV class with margin for typical utility swings. At 3130 kVA apparent power and 2617 kW motor power, this is a medium-voltage drive sized for large induction or synchronous motors — think mainline conveyors, mill drives, or large pumps in mining and water.
Overload profile and fault-withstand capability
Standard overload rating is 1.2 × In for 60 s and 1.5 × In for 3 s; the high-overload profile pushes to 1.5 × In for 60 s and 1.85 × In for 3 s. That high-overload envelope suits applications with heavy starting duty or short-duration peak loads — crushers, extruders, or centrifuge starts. The prospective line short-circuit current is 31.5 kA for 150 ms, which means the drive's input section can ride through a fault on the primary distribution bus without collapsing the DC bus or damaging the rectifier bridge. Dielectric strength between earth and power terminals is 20 kV AC — a safety margin that reflects the medium-voltage isolation requirements.
Physical footprint and cooling — what ships in the enclosure
The drive ships as a floor-standing enclosure with separate air flows for the power cells and the transformer section. Standard-efficiency configuration: 5770 mm wide × 2670 mm high × 1600 mm deep; high-efficiency variant adds width to 6070 mm and depth to 1700 mm. The product composition includes the phase-shifting transformer, 15 power cells, medium-voltage arrestors, cooling fans, and the HMI. Cooling is forced convection at 29,700 m³/h for both efficiency grades. Noise level is 80 dB — plan for hearing protection zones around the drive room.
Compliance and standards package
CE marked. Designed to EN/IEC 61800-3 (EMC environment), EN/IEC 61800-4 (voltage sag immunity), EN/IEC 61800-5-1 (electrical safety), EN/IEC 60204-11 (semiconductor converter equipment), and EN/IEC 60529 (enclosure ingress protection). Pollution degree 2 per EN/IEC 61800-5-1. Overvoltage category II. The integrated EMC filter covers conducted emissions for the drive's rated power — no external filter needed for most industrial installations.
