The Schneider ATV6000C550A3333NA3 is an Altivar Process ATV6000 medium-voltage variable frequency drive rated for 5500 kVA apparent power and 4400 kW motor power under normal duty, with a heavy-duty rating of 3820 kW. It uses an 18-pulse diode rectifier input stage to keep line-side harmonics below 3% THDI, meeting IEEE 519-1992 without an external filter. The drive is in a floor-standing enclosure measuring 6060 mm wide, 3151 mm high, and 1800 mm deep.
The 5500 kVA apparent power and 4400 kW normal-duty motor rating tell you this drive is sized for large induction, synchronous, or permanent-magnet motors in the multi-megawatt class. Line current at normal duty is 962 A; heavy duty drops to 829 A. The 18-pulse rectifier keeps input harmonics low enough that you can skip a separate line filter in most installations. Power losses run 166.6 kW at normal duty, so the forced-convection cooling system and the cabinet's thermal design need to be factored into the room's HVAC budget.
The drive carries EAC and CE marking and is designed to IEC 61800-3 (EMC and adjustable-speed drive standards), IEC 61800-4, IEC 61800-5-1 (safety), IEC 60529 (enclosure), IEEE 519:1992 (harmonic control), and EN/IEC 60076 (transformers). An integrated EMC filter meets category C3 for the control section and C4 for the power section per IEC 61800-3.
What's in the box and how it connects
The drive ships as a complete assembly including power cells, phase-shifting transformer, cooling fans, a 10-inch LCD touch-screen HMI, medium-voltage arrestors, enclosure, and plinth. Cable entry is from the bottom. Communication options cover Profibus DP V1, PROFINET, DeviceNet, CANopen, EtherCAT, and dual RJ45 ports for Ethernet IP/Modbus TCP plus one for Modbus serial. Control I/O includes eight programmable digital inputs (two configurable as pulse inputs up to 30 kHz), configurable analog inputs and outputs, and three relay outputs.
