The 36-pulse diode rectifier bridge on the input side means the drive draws line current at 410 A with significantly lower harmonic distortion than a 6- or 12-pulse topology — you can often skip a dedicated harmonic filter at the point of common coupling. Supply voltage range is 2970-3630 V, so this drive is built for 3.3 kV-class distribution systems common in heavy industrial sites, not the 400/480 V world. Overload capability is defined by two profiles: standard overload allows 1.2× rated current for 60 s or 1.5× for 3 s; high overload pushes to 1.5× for 60 s and 1.85× for 3 s — the high-overload curve is the one to use for a crusher or centrifuge start that needs extra torque through the breakaway. ## Floor-standing enclosure and site planning The drive ships in a floor-standing enclosure with separate air flows for the power cells and transformer — the standard-efficiency variant measures 1700 mm deep × 6670 mm wide × 2740 mm high; the high-efficiency version adds 100 mm in depth, 300 mm in width, and 300 mm in height. Forced convection cooling moves 49,800 m³/h of air through the cabinet — that volume demands a clean, unobstructed intake path and an exhaust routed outside the electrical room to avoid recirculating hot air. Operating altitude is 1000-2000 m with a 0.6% current derating per 100 m above 1000 m — if your site sits at 1500 m, budget a 3% reduction in available output current. Acoustic noise is rated at 80 dB — that's loud enough to require hearing protection within a few meters; plan the drive location away from operator stations or add an enclosure barrier. ## Compliance and dielectric integrity CE marked and compliant with EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (drive requirements), and EN/IEC 61800-5-1 (electrical safety for adjustable-speed drives). Dielectric strength between earth and power terminals is 20 kV AC — that's the insulation coordination for a 3.3 kV-class drive, not a low-voltage unit. Pollution degree 2 per EN/IEC 61800-5-1 means the drive is rated for normally non-conductive pollution, but occasional condensation is acceptable — typical of a climate-controlled electrical room. Prospective line short-circuit current withstand is 31.5 kA for 150 ms — the upstream breaker or fuse must be coordinated to clear within that window to protect the drive's input rectifier. ## Internal architecture and I/O The drive is built from 18 power cells fed by a phase-shifting transformer — this multi-cell topology delivers near-sinusoidal output voltage, reducing motor heating and bearing current issues common with two-level VFDs. Four analogue inputs (software-configurable 0-20 mA or 4-20 mA, 250 Ω impedance) and six discrete inputs (expandable to ten with an option card) give enough I/O for a basic speed reference, start/stop, and a few feedback signals without adding remote I/O. Electrical connection on the input side uses M10 bar-type screw terminals accepting up to 6 × 40 mm² conductors, entry from bottom or top — plan the cable tray elevation before the drive arrives on site. The integrated EMC filter and electrical isolation between power and control sections simplify panel layout — no external isolation transformer needed for the control supply in most installations. No direct pin-compatible alternative exists within the Altivar 1200 family — this order code is the specific configuration for 3917 kW motor power with the 36-pulse input and standard overload profile.","metaTitle":"Schneider ATV1200A46856666 AC Drive, 3917 kW, 4685 kVA","metaDescription":"Schneider Electric ATV1200A46856666 AC drive, 3917 kW motor power, 4685 kVA apparent power. 36-pulse input, 2970-3630 V supply.
