The Siemens SIDAC 4EU4351-0AE00 is a 3-phase output reactor (line reactor) rated for 117 A continuous current at a switching frequency of 8000 Hz. That 8000 Hz figure is the carrier frequency the reactor is designed to handle from a PWM drive output — not the motor's running frequency. The 0.2 mH inductance smooths the voltage spikes and limits the rate of rise of current (di/dt) from the drive's IGBT switching, which protects the motor windings and extends cable runs.
The reactor measures 0.46 m wide by 0.43 m tall by 0.26 m deep — that's roughly 18 by 17 by 10 inches. It's a floor-mount or chassis-mount piece; no DIN-rail clip. The main circuit connects via flat-type terminals (bus-bar style), so plan for lug or bar connections, not screw-clamp wire terminations. Rated ambient is 40 °C with Class H insulation (180 °C thermal class per IEC 60085), which gives headroom for hot cabinet interiors.
