That 18-pulse input topology inherently cancels the 5th and 7th harmonics at the primary, which means the drive meets IEEE 519 current distortion limits without a separate harmonic filter on most utility feeds — a real advantage when the site electrical engineer is chasing THD compliance at the PCC. ## Overload duty and fault current coordination Standard overload rating holds 1.2× rated current for 60 seconds and 1.5× for 3 seconds; the high-overload profile steps to 1.5× for 60 seconds and 1.85× for 3 seconds — choose the profile that matches the starting duty of the driven load (conveyor vs crusher vs pump). The drive withstands 31.5 kA prospective line fault current for 150 ms, which sets the SCCR floor for the upstream protection coordination — the site electrical engineer needs this figure to verify selectivity with the incoming MV breaker. Dielectric strength is 10 kV AC between earth and power terminals, and pollution degree 2 per EN/IEC 61800-5-1, so the drive is rated for normal industrial environments where conductive contamination is limited. ## Physical footprint and cooling requirements Floor-standing enclosure with separate air flows for power cells and control section. Standard-efficiency configuration measures 1400 mm deep × 2760 mm wide × 2520 mm high; the high-efficiency variant adds depth to 1500 mm, width to 3360 mm, and height to 2670 mm. Forced convection cooling moves 9900 m³/h (standard) or 16500 m³/h (high efficiency) — the plant MRO planner must verify the room's HVAC capacity can reject that heat load without the drive room ambient climbing above the 40°C typical ceiling. Operating altitude derating starts at 1000 m: 0.6 % per 100 m above that up to 2000 m. Above 2000 m the drive requires a factory derating study — not a field adjustment. ## Internal architecture and auxiliary supply The drive is built from 2 plinths, a phase-shifting transformer, 9 power cells, medium-voltage arrestors, cooling fans, and an HMI — the cell-based topology means a failed cell can be swapped without decommissioning the whole drive, keeping the line running at reduced capacity until the replacement arrives. Control electronics require an external 220 V AC supply at 3 kVA; the cooling fan runs from an internal 380 V AC supply. An optional external 220 V AC/DC control supply is available, which lets the controls stay alive during a main power loss for orderly shutdown sequencing. Four software-configurable analogue inputs (0-20 mA / 4-20 mA, 250 Ω impedance) and six discrete inputs (expandable to ten) give the commissioning engineer enough I/O for speed reference, feedback, and basic interlocking without an additional remote I/O rack. CE marked, with design compliance to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3 (EMC), EN/IEC 61800-4, and EN/IEC 61800-5-1. The integrated EMC filter covers conducted emissions for the second environment (industrial power networks). Electrical isolation between power and control sections means the 24 VDC control loop stays referenced to ground, not floating at MV potential — a detail the safety auditor will check against the machine directive. If the BOM specifies this exact order code, there is no drop-in substitute to source instead.","metaTitle":"Schneider ATV1200A7703333 AC Drive, 644 kW, 770 kVA","metaDescription":"Schneider Electric ATV1200A7703333 Altivar 1200 medium-voltage AC drive. 644 kW / 770 kVA, 18-pulse input, 2970-3630 V supply.
