The Siemens 4EP3600-2DS00 is a 3-phase commutating choke (line reactor) for converter applications, rated 400V AC at 50 Hz with a rated current of 22.5 A and a maximum current of 25 A. This choke sits between the line supply and a variable-frequency drive or DC drive input, limiting current rise during commutation and reducing harmonic distortion on the mains. The 2% voltage drop means it's a relatively small impedance — it smooths switching edges without dropping significant line voltage under load. Rated for 40 °C ambient with thermal class B insulation, dissipating 39 W in the coil and 8.3 W in the iron core at full load. IP00 enclosure means it mounts inside a cabinet.
Measures 0.148 m wide, 0.139 m high, and 0.078 m deep. Because it's IP00 and open-frame, plan for at least 20 mm clearance around the choke inside the cabinet for airflow. The 39 W coil loss and 8.3 W iron loss add up to about 47 W of heat to vent — not a lot, but enough to consider in a densely packed panel.
