What this drive delivers for a medium-voltage motor line
The ATV1200A71001010 is a Schneider Electric Altivar 1200 AC drive rated for 5936 kW motor power with 7100 kVA apparent power — sized for large asynchronous motor loads like pumps, fans, and compressors in medium-voltage installations. It draws 410 A line current from a 2970–3630 V supply through a 48-pulse diode rectifier bridge, which keeps input harmonics low enough to meet EN/IEC 61800-3 without external filtering.
Overload profile and fault handling
Standard overload rating holds 1.2× rated current for 60 seconds and 1.5× for 3 seconds; a high-overload setting pushes to 1.5× for 60 seconds and 1.85× for 3 seconds — choose the profile that matches your motor's starting duty cycle. The drive withstands a prospective line fault of 31.5 kA for 150 ms, so it coordinates with upstream protection without requiring a separate current-limiting reactor in most medium-voltage switchgear arrangements. Ground fault protection is built into the drive, and the dielectric strength between earth and power terminals is 28 kV AC — a margin that supports direct connection to ungrounded or resistance-grounded distribution systems.
Physical footprint and installation constraints
The drive ships in a floor-standing enclosure measuring 3040 mm high by 9370 mm wide by 1700 mm deep — plan for a dedicated equipment room with a reinforced floor and overhead lifting access. Forced convection cooling moves 66400 m³/h of air; the enclosure separates internal airflows so the power cells and transformer each get their own thermal path — ducting to a plant exhaust system is recommended to avoid recirculating 80 dB noise. Power connections use M10 screw-type bars accepting up to 6 × 40 mm² cable per phase, entry from top or bottom — coordinate the gland plate and cable tray layout before the enclosure arrives on site.
System composition and control wiring
The ATV1200A71001010 includes two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 24 power cells — it arrives as a near-complete drive system, not a bare chassis. Control power requires an external 220 V AC supply at 3 kVA; the internal fan supply is 380 V AC. Optional external control supply at 220 V AC/DC and optional external fan supply at 380 V AC allow separate upstream UPS feeds for the control electronics. Four software-configurable analogue inputs (0–20 mA / 4–20 mA, 250 Ω impedance) and six discrete inputs (expandable to ten) handle speed reference and run commands — the I/O count is modest for a drive of this class, so plan for a remote I/O rack if the application needs more than a few signals.
Compliance and environmental limits
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 — covers electrical safety, EMC, and enclosure protection for industrial drive installations. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II — the drive is intended for a clean, controlled environment (no conductive dust or condensation). Relative humidity range is 0–90 % (0–95 % optional), and the drive must be mounted vertically within ±10° — factor this into the enclosure layout and HVAC design.
