Product details

It's rated for 690 V AC at 50 Hz, handles a maximum continuous current of 125 A, and is specified at a rated current of 112.5 A. The 0.2 mH inductance (0.0002 H) with a 2 % relative inductive voltage drop at rated conditions means it's sized to do its job without dropping so much voltage that the drive underperforms. The IP00 enclosure is open-frame — this goes inside a cabinet, not out in the weather.

The 125 A maximum and 112.5 A rated current tell you this choke is meant for a drive in the 55–75 kW range on a 400 V system, or larger on a 690 V line — the rated current is the continuous thermal limit at 40 °C ambient. The 140 W coil loss plus 44 W iron-core loss (184 W total) is the heat you have to vent from the enclosure; that's not trivial in a sealed cabinet. The flat-type terminals are heavy-duty bus-bar lugs, not screw-clamp wire terminals; plan your cable lugs accordingly.
