The Siemens 4EP3600-8DS00 is a three-phase commutating choke for converter front-end duty. It limits current rise rates and reduces harmonic distortion. Rated for 400 V AC at 50 Hz, it carries 16.2 A continuous with 18 A maximum.
The 16.2 A rated current (18 A maximum) at 400 V AC three-phase sets the continuous load this choke can handle without exceeding its thermal class B (130 °C) insulation system. The 39 W coil loss and 9.1 W iron core loss total about 48 W of heat that must be dissipated into the enclosure — IP00 means no enclosure of its own, so it relies on the panel's airflow. The DC rated value of 22 A indicates the choke can handle a higher DC-side current, which matters if the converter's DC-link current exceeds the AC line rating — for example, in a regenerative drive or one with a high crest factor.
The 4EP3600-8DS00 measures 0.148 m wide by 0.139 m tall by 0.078 m deep. The 3-phase design with a common core means all three lines share the same magnetic path; verify that the panel's phase-to-phase and phase-to-ground clearances meet the 400 V AC working voltage.
