What this MV drive delivers at the shaft
The ATV1200A51006060 is a medium-voltage Altivar 1200 drive rated for 4264 kW motor power at a supply voltage of 2970 to 3630 V. It drives both synchronous and asynchronous motors, making it a single-drive option for a range of large rotating loads — pumps, compressors, fans, conveyors — where the motor type may differ between plant sections. The 30-pulse diode rectifier input stage draws a line current of 490 A and presents an apparent power of 5100 kVA. The multi-pulse topology reduces line-side harmonics below IEEE 519 thresholds without an external filter — the integrated EMC filter handles the conducted emissions side.
Overload profile and fault handling
Overload capability is defined at two duty levels: standard overload handles 1.2× In for 60 s or 1.5× In for 3 s; high overload handles 1.5× In for 60 s or 1.85× In for 3 s. The 60 s window at 1.5× In in high overload covers most starting and load-impulse scenarios for medium-voltage motors — a crusher or centrifuge start that needs 150 % torque for 40 s stays inside the curve. Prospective line short-circuit current is rated at 31.5 kA for 150 ms — the drive's input section withstands this fault level without upstream fusing intervention, provided the supply transformer and cabling are coordinated for that let-through. Ground fault protection is integrated into the drive, not left to an external relay. Dielectric strength between earth and power terminals is 20 kV AC, consistent with the 3.3 kV class insulation system. Pollution degree 2 per EN/IEC 61800-5-1 means the drive is intended for a clean, climate-controlled electrical room — not a dusty or conductive environment.
Physical footprint and cooling
The drive ships in a floor-standing enclosure with separate air flows for the power cells and control section. Standard efficiency dimensions: 1700 mm deep × 6070 mm wide × 2820 mm high; high efficiency variant adds depth to 1800 mm and height to 3040 mm, with width expanding to 6370 mm. Forced convection cooling moves 70000 m³/h of air through the enclosure — this volume dictates the room ventilation design. The noise level at full cooling is 80 dB, which requires hearing protection within the equipment aisle during operation. Operating altitude up to 1000 m is full-rated; above that, derate current by 0.6 % per 100 m up to 2000 m. The drive must be mounted vertical within ±10° — a floor bolt-down on a level pad is the intended installation.
Control wiring and I/O complement
Four software-configurable analogue inputs accept 0-20 mA or 4-20 mA signals at 24 V max, 250 Ω impedance. Two analogue outputs mirror the same current ranges. Discrete inputs number six standard, expandable to ten with an option — enough for run/stop, speed select, and fault reset without an external I/O block. Control power requires an external 220 V AC supply at 3 kVA. The cooling fan runs from a separate 380 V AC supply — this isolation means the fan can stay on for post-run cooldown even when the control circuit is off. An optional 220 V AC/DC control supply is available for sites with DC control buses. Electrical connection at the line side uses M10 bar-type screw terminals with a clamping capacity of 6 × 40 mm² per phase. Entry can be from the bottom or top — a detail that matters when laying out cable trenches versus overhead trays.
The drive carries CE marking and complies with EN/IEC 60204-11 (electrical equipment of machines), EN/IEC 60529 (enclosure protection), EN/IEC 61800-3 (EMC for adjustable-speed drives), EN/IEC 61800-4 (functional safety), and EN/IEC 61800-5-1 (electrical safety). These standards cover the full scope of a medium-voltage drive installation in an industrial environment. Electrical isolation between power and control circuits is maintained — a requirement for safe troubleshooting when the drive is powered but the motor is stopped. The enclosure is grey RAL 7032, the standard industrial cabinet colour across Schneider's MV drive range.
