5141 kW / 6150 kVA — medium-voltage drive for large synchronous and asynchronous motors
The Schneider Electric ATV1200A61504242 is an Altivar 1200 medium-voltage AC drive rated for 5141 kW motor power and 6150 kVA apparent power, supplied from a 2970…3630 V line. It drives both synchronous and asynchronous motors, making it a fit for large pumps, compressors, conveyors, and fans in heavy industrial processes. The 24-pulse diode rectifier bridge input reduces line-side harmonics below IEEE 519 thresholds without external filters — a key advantage for sites with weak utility connections or strict power-quality requirements.
Architecture: 12 power cells, floor-standing, separate air flows
The drive is assembled in a floor-standing enclosure with separate air flows for the power section and control electronics, which keeps the control compartment cooler and extends component life. It comprises 2 plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, an HMI, and 12 power cells — a modular cell topology that allows partial operation if a cell fails (n-1 redundancy). Forced convection cooling moves 70,000 m³/h of air (standard efficiency), so the installation room must have adequate intake and exhaust louvres sized for that flow.
Overload profile and fault withstand
Standard overload rating: 1.2 × In for 60 s and 1.5 × In for 3 s. High overload rating: 1.5 × In for 60 s and 1.85 × In for 3 s. This covers heavy starting duty cycles for crushers, mills, and extruders. The drive is rated for a prospective line short-circuit current of 31.5 kA for 150 ms — the upstream protection must coordinate to clear within that window. Dielectric strength is 20 kV AC between earth and power terminals, with electrical isolation between power and control circuits.
Compliance, environment, and lifecycle
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. Pollution degree 2 per EN/IEC 61800-5-1. Ambient relative humidity 0…90 % (0…95 % optional). Lifecycle status is current production — this is an active catalog item, not a legacy or end-of-life part. Sourced to order against RFQ through authorized distribution.
