It's a 3-phase reactor rated for 500V AC at 50 Hz, with a rated current of 180A and a maximum current of 200A. The 0.18mH inductance and 4% relative inductive voltage drop smooth out line harmonics and limit inrush current, protecting the drive's rectifier stage from voltage spikes and reducing total harmonic distortion on the line side.
Sizing and thermal reality
The 180A rated current is the continuous duty figure at 40°C ambient with Class H insulation (180°C rated temperature rise per IEC 60085). The total power loss breaks down to 220W in the coil and 87W in the iron core — 307W total that has to leave the enclosure. At IP00 there's no housing; this choke sheds heat directly into the cabinet air. In a sealed panel, that heat load needs to be factored into the cooling budget. The 200A maximum rating is the short-term overload ceiling, not a continuous operating point.
This is a panel-mount component — no DIN rail clip. Dimensions are 0.3m wide by 0.269m tall by 0.221m deep. The main circuit connection uses flat-type terminals, so you'll need ring or fork lugs sized for the cable that carries 180A continuous. The IP00 rating means it's open-frame; install it where no accidental contact can occur during operation, or provide supplementary guarding.
