The ATV1200A39406666 is a medium-voltage drive rated for 3294 kW motor power at a supply voltage of 2970...3630 V — this is not a 400 V or 690 V unit; it lands in the 3.3 kV class, requiring MV switchgear and transformer coordination upstream. The 36-pulse diode rectifier input delivers low line-current harmonics without an active front end — the line current draws 410 A at an apparent power of 3940 kVA. The prospective short-circuit current withstand is 31.5 kA for 150 ms, which sets the upstream fuse or breaker rating. Overload capability is defined in two profiles: standard overload handles 1.2 In for 60 s and 1.5 In for 3 s; high overload handles 1.5 In for 60 s and 1.85 In for 3 s. This dictates the motor duty cycle the drive can support without tripping.
Physical footprint and installation constraints
The drive ships in a floor-standing enclosure with separate air flows for power and control sections. Dimensions: 1700 mm deep, 6670 mm wide, and either 2670 mm (standard efficiency) or 2970 mm (high efficiency) tall. Cooling is forced convection requiring 33,000 m³/h of cooling air. The operating position is vertical ±10°. Ambient conditions: pollution degree 2 per EN/IEC 61800-5-1, relative humidity 0–90% (0–95% optional), and altitude derating of 0.6% per 100 m above 1000 m. Power connection uses bar-type screw terminals M10, clamping 6 x 40 mm² per phase, with cable entry from top or bottom. The dielectric strength between earth and power terminals is 20 kV AC.
Compliance and standards coverage
CE marked, with design compliance to EN/IEC 60204-11 (safety of machinery), EN/IEC 60529 (enclosure protection), EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (harmonics), and EN/IEC 61800-5-1 (electrical safety). An integrated EMC filter and electrical isolation between power and control reduce external filtering requirements. The drive includes ground fault protection and overvoltage category II per the same standard.
Sourcing — active production, quoted to order
Sourced through authorized distribution channels. Pricing and lead time are confirmed at RFQ against the BOM quantity — no stock-holding claim on a unit of this size and value.
