Rated for 126 A continuous with a 140 A maximum thermal current at 500 V AC, 50 Hz. The 0.00026 H inductance value is wound for that specific current and frequency.
The 0.27 m width, 0.248 m height, and 0.208 m depth footprint needs a clear panel area; account for the flat-type terminal connections on the main circuit when laying out bus bars or cable lugs. Class H insulation (180 °C thermal class per IEC 60085) means the choke can run hot internally without degrading the winding insulation — useful in a crowded cabinet where ambient air circulation is limited. The total power loss splits into 179 W in the copper windings and 68 W in the iron core; that 247 W combined heat must be vented or the panel's thermal budget must absorb it.
