The SIDAC 4EU2752-0ES00-1BA0 is a 3-phase output reactor (output choke) rated for AC voltage, designed to limit dv/dt and peak currents on the output of a variable-frequency drive. It handles a maximum continuous current of 150 A and a switching (carrier) frequency of 8 kHz, with an inductance of 0.0002 H (0.2 mH). Rated ambient temperature is 40 °C, and the thermal class H (IEC 60085) insulation system allows a 180 °C temperature rise on the winding — common for reactor duty in high-switching-frequency drive applications where iron losses dominate.
The reactor is designed for a fundamental frequency range of 120 Hz to 410 Hz, covering most high-speed motor applications above line frequency. The switching frequency of 8 kHz is the carrier frequency the reactor is designed to filter — if your drive runs at a different PWM carrier (e.g., 4 kHz or 16 kHz), the core losses and temperature rise will shift. The 23 % impedance voltage (Uk) is a measure of the voltage drop at rated current, which affects motor torque at low speeds. Power loss splits into 220 W coil loss (copper) and 180 W iron core loss (magnetic), totaling 400 W at full load. This heat must be dissipated inside the cabinet — factor it into your enclosure cooling calculation.
Mounting and connection
Terminals are flat-type connectors — expect bus-bar or crimp-lug connections, not screw-clamp or spring-cage. The footprint is 0.27 m wide × 0.24 m high × 0.18 m deep (–). Mount it on a flat panel or chassis inside the cabinet; IP00 means no touch protection — keep clearance for live parts per local wiring rules.
