The Siemens SIDAC 4EP3200-0BS00 is a 3-phase output reactor rated for 4 A continuous, with a rated inductance of 0.00012 H and a switching frequency of 8 kHz.
The 4 A current rating is the thermal maximum at 40 °C ambient. The 8 kHz switching frequency matches the typical IGBT carrier frequency of modern drives. The 0.12 mH inductance gives a voltage drop of roughly 1.7% at 4 A and 50 Hz (calculated from the 0.15% UK figure in the description). That's low enough to avoid starving the motor of torque, but high enough to limit peak voltage reflections on a cable run of 50–100 m. The thermal class B (130 °C) insulation system means the reactor can run at its full rating in a 40 °C ambient without exceeding the winding temperature limit. IP00 means no enclosure — the reactor is an open-frame component. Screw-type and tab terminals accept ring lugs or fork terminals.
This output reactor mounts in the motor branch circuit, between the drive output terminals (U, V, W) and the motor cable. It's not a line reactor — it goes on the load side, not the supply side. The 0.05 m depth, 0.08 m width, and 0.1 m height make it compact enough to fit on a DIN-rail mounting plate or directly on the panel backplane, but verify the screw-terminal clearance for the tab connections.
