What this drive delivers — 6228 kW at medium voltage
The ATV1200A74505555 is a Schneider Electric Altivar 1200 medium-voltage AC drive rated for 6228 kW motor power with 7450 kVA apparent power. Input voltage limits are 2970 to 3630 V AC, fed through a 30-pulse diode rectifier bridge that keeps line-side harmonics low enough to skip a separate filter in many installations. This is a floor-standing unit — the assembly style is an in-floor-standing enclosure with separate air flows for the power section and control electronics. The enclosure measures 3040 mm high by 8970 mm wide by 1700 mm deep (standard efficiency variant) and requires 90000 m³/h of cooling air through forced convection.
Overload profile and protection
Overload withstand is specified for both standard and high-overload duty cycles: 1.2× In for 60 s or 1.5× In for 3 s under standard overload; 1.5× In for 60 s or 1.85× In for 3 s under high overload. The drive includes ground-fault protection on the drive side and has a dielectric strength of 20 kV AC between earth and power terminals. Prospective line short-circuit current rating is 31.5 kA for 150 ms, and the unit carries CE marking with compliance to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II apply.
What ships in the enclosure
The product composition includes 2 plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 15 power cells. Control supply is 220 V AC at 3 kVA external; the cooling fan runs on 380 V AC internal supply, with optional external supply variants for both. Electrical connection uses bar-type screw terminals M10 with clamping capacity for 6 x 40 mm² conductors on /R, /S, L3/T, entry from bottom or top. The enclosure colour is grey RAL 7032.
