The SIDAC 4EU2452-0EE00-4BA0 is a 3-phase output reactor (choke) designed for AC motor drives and inverters, rated at a 4000 Hz switching frequency with a maximum of 8000 Hz. It carries 0.25 mH inductance and is built to thermal class H per IEC 60085, meaning the insulation system withstands 180 °C hot-spot temperature — critical for sustained operation in high-ambient cabinets or alongside heat-generating drives.
The 4000 Hz rated switching frequency (8000 Hz max) matches the typical carrier frequency of modern IGBT-based drives. If your drive is set to a 4 kHz PWM carrier, this reactor is sized for that pulse content — not just the 50/60 Hz output. The 0.25 mH inductance provides enough impedance to limit motor cable charging currents and reduce reflected-wave voltage spikes on long cable runs. The 98 W coil loss plus 42.6 W iron loss (140.6 W total at rated load) must be accounted for in the cabinet thermal budget; a panel with restricted airflow may need forced ventilation or derating above the 40 °C ambient rating. Termination is via flat-type connectors, not screw-clamp or ring-lug. Verify that your drive output bus bars or cable lugs mate with a flat interface before panel layout. The footprint is 0.22 m wide by 0.21 m tall by 0.13 m deep — a compact block that fits on a standard mounting plate without consuming excessive DIN-rail width.
