The Siemens SIDAC 4EU2531-5AB00-0A is a 3-phase output reactor (output choke) rated for 97 A at 410 Hz with a switching frequency of 8 kHz. Its 0.2 mH inductance limits the rate of current rise from the drive's PWM output, protecting the motor windings and cable insulation from voltage spikes and reflected-wave damage on long cable runs. Rated for a 400 V AC supply and built to thermal class H (180 °C insulation system) per IEC 60085, with a 40 °C ambient rating.
Dimensions are 0.22 m wide × 0.21 m tall × 0.16 m deep. Mounting is panel-mount inside the enclosure; no DIN-rail clip on this form factor.
