The Siemens SIDAC 4EU3052-0AM30-1BA0 is a three-phase output reactor (output choke) rated for 130 A maximum continuous current and 6000 Hz rated frequency, with an inductance of 0.3 mH. It sits between a variable-frequency drive and the motor to limit the rate of voltage rise (dV/dt) and reduce reflected-wave stress on motor windings, especially on long cable runs. Thermal class H (180 °C insulation system) per IEC 60085 gives it headroom for high-ambient or overload conditions up to 40 °C ambient temperature.
The 130 A maximum current (Ithmax) is the thermal continuous rating — size your drive output to stay at or below this value to avoid saturating the core. The 6000 Hz rated frequency (F1) is the fundamental output frequency the reactor is designed for; it will handle the switching harmonics from a PWM drive but is not a switching-frequency spec. The 0.3 mH inductance (300 µH) determines the dV/dt limiting effect — lower inductance gives less filtering, higher inductance increases voltage drop. The 3.9 % impedance (Uk) at rated conditions is a typical figure for this class of reactor. The flat-type terminals (flat connector) accept busbar or cable lugs; verify your lug width fits the terminal pad.
