The Siemens SIDAC 4EU2432-0EG00-0AA0 is a 3-phase output reactor (also called an output choke) rated for 180 A maximum continuous current and a switching frequency of 10 000 Hz. It sits between a variable-frequency drive and the motor, smoothing the PWM waveform to reduce voltage spikes, motor bearing currents, and cable reflections — especially on long motor leads. That 10 kHz switching-frequency rating means it's tuned for modern IGBT drives running fast PWM, not the old 2–4 kHz generation.
The 180 A maximum current is the thermal limit under continuous operation at 40 °C ambient. That's a beefy reactor — sized for a motor in the 90–110 kW range on 400 V class drives, depending on duty cycle. The inductance is 0.000006 H (6 µH), which is low enough to keep voltage drop under a few percent at line frequency, but still provides enough dv/dt filtering to protect motor windings on drives with short cable runs under 50 m. The rated voltage from the description is 200 V, so this is a low-voltage reactor for 200 V class drives, not 400 V or 690 V systems. Thermal class H per IEC 60085 means the insulation system can handle 180 °C hot-spot temperature. That's important for a reactor sitting in a drive cabinet where ambient might be 40 °C and the iron core dissipates 40 W plus the coil dissipates another 95 W — total 135 W of heat that has to rise out of the IP00 enclosure. No fan, no filter — just natural convection. Mount it with clearance above and below for airflow. IP00 means no ingress protection — it's an open-frame component. This reactor belongs inside a cabinet or an enclosure, not out on the plant floor where washdown or dust is a concern. Plan for a bolted connection.
This output reactor mounts between the drive output terminals and the motor cable. It's a 3-phase device, so it goes on all three motor phases. The dimensions are 0.22 m wide by 0.21 m tall by 0.13 m deep — roughly 8.7 by 8.3 by 5.1 inches. That's a compact footprint for a 180 A reactor, but it's not a DIN-rail mount; it's a panel-mount component. Plan for four mounting bolts and leave at least 100 mm clearance top and bottom for natural convection cooling.
