The inductance is 41 µH with a relative inductive voltage drop of 4% at rated conditions. This is a high-current line reactor designed to limit di/dt and reduce harmonic distortion on the input side of a variable-frequency drive or DC drive converter.
The 980 A maximum (882 A rated) at 690 V AC places this choke squarely in the heavy industrial drive segment — think 500+ kW motors on pumps, conveyors, or compressors in a 690 V plant. The 41 µH inductance is the actual energy-storage figure that governs the current ripple smoothing. IP00 means no enclosure — this is a chassis-mount component intended for a ventilated cabinet. The 0.46 m width, 0.435 m height, and 0.265 m depth define the physical footprint; plan for adequate clearance around the flat-type terminals for busbar or cable lugs. The 680 W coil loss plus 325 W iron core loss totals about 1 kW of heat to vent from the enclosure. Thermal class H (180 °C) winding insulation means the choke can run hot without degrading — relevant if your ambient hits 40 °C and the cabinet has limited airflow. The EN 61558-2-20 compliance covers safety of transformers and reactors; the UL/CSA recognition means it's accepted for North American panels without additional agency review.
