The Siemens 4EU2752-0EP00-0BA0 is a three-phase line reactor (Drossel) rated for 400 V AC at 50 Hz, carrying 104 A continuously and peaking at 116 A. Its 0.5 mH inductance smooths current ripple and limits harmonic distortion on the line side of a variable-frequency drive or power supply — the kind of component you spec into a panel to protect upstream switchgear from drive-induced harmonics. The 320 W coil loss and 123 W iron-core loss at rated load tell you the thermal budget: at 40 °C ambient, this choke sheds about 443 W total. Thermal class H (180 °C insulation system) means the winding can handle sustained hot-spot temperatures without degrading — a real advantage in a crowded cabinet where airflow is tight.
IP00 means no enclosure — this is a panel-mount component that needs a cabinet around it. The flat-type terminals on the main circuit accept busbar or crimp lugs; plan for a 0.27 m width × 0.248 m height × 0.208 m depth footprint on the mounting plate. No DIN-rail clip here; it bolts directly to the chassis.
