It sits between the supply and the drive, limiting harmonic distortion, reducing peak currents, and protecting the drive rectifier from line transients. The 0.79 mH inductance at 35.5 A yields a 4% relative inductive voltage drop at rated current and frequency, which is the standard sizing for most general-purpose drive applications.
Rated for 400/480 V AC, 50/60 Hz, three-phase. The maximum continuous current is 35.5 A, with a rated operational current of 31.95 A at 40 °C ambient. The power loss splits into 65 W in the coil and 20 W in the iron core.
This is an open-frame choke, IP00 — no enclosure. Dimensions are 0.219 m wide, 0.179 m tall, 0.123 m deep. Connections are screw-type terminals. The thermal class is B.
