The Siemens SIDAC 4EP4010-0CS00 is a 3-phase output reactor rated for a maximum continuous current of 17 A at 690 V AC, with a rated switching frequency of 5.4 kHz and an inductance of 1 mH. It's built to EN 61558-2-20 and carries thermal class B insulation per IEC 60085, meaning the winding temperature rise is limited to 130 °C total at a 40 °C ambient — a standard spec for motor-drive output filtering in industrial panels.
The 17 A maximum current is the thermal limit under continuous duty at 40 °C ambient; derate above that. The 5.4 kHz switching frequency matches common IGBT drive outputs in the 4–8 kHz range — if your drive runs a higher carrier frequency, the core losses climb and you'll need a derated or larger reactor. The 1 mH inductance and 7.44 % voltage drop (UK) are sized for motor cable runs up to about 100–150 m on a standard 400 V drive, limiting dv/dt stress on the motor windings. IP00 means no enclosure — it's a bare core-and-coil assembly intended for mounting inside a cabinet with at least IP2X protection on the panel door. The screw-type and tab terminals accept ring lugs or fork terminals; plan for a 0.21 m wide × 0.17 m tall footprint with 0.14 m depth, plus clearance for air flow around the core.
Power loss splits into 65.2 W in the coil (copper losses) and 43.2 W in the iron core (hysteresis and eddy-current losses), totalling roughly 108 W dissipated as heat inside the cabinet. That's not trivial — factor it into your panel thermal budget, especially if the reactor shares an enclosure with the drive.
