The SIDAC 4EU2732-0CP08-4BA0 is a 3-phase filter reactor — a line-reactor / choke designed to limit harmonic currents, reduce voltage notching, and protect downstream capacitors and drives in power-factor-correction and drive-input circuits. Rated 44.1 A continuous with a 49 A maximum, it operates at 690 V AC, 50 Hz, and delivers 50 kvar of reactive power from the filter bank. The 7% relative throttling factor means it drops roughly 7% of the line voltage at rated current, which is the standard impedance for harmonic mitigation in industrial networks.
The 44.1 A rated current (49 A maximum) sets the thermal limit for continuous motor or capacitor-bank loads. At 690 V AC phase-to-phase, this reactor suits 400 V to 690 V networks common in European and export panels. The 0.0023 H inductance and 189 Hz resonant frequency define the filter's tuning point — it presents a high impedance at the 5th and 7th harmonics (250–350 Hz) while passing the 50 Hz fundamental with low loss. The 40 °C ambient rating is the design baseline; above that, derate current per the manufacturer's curve (not provided here, but standard for class H).
This is a panel-mount reactor, not a DIN-rail clip-on. Dimensions 0.27 m wide × 0.248 m tall × 0.187 m deep — roughly 270 × 250 × 190 mm. The flat-connector / screw-type terminals accept lug or busbar connections for the main circuit. IP00 means no built-in touch protection; the reactor must be installed behind a panel door or inside a locked cabinet. Plan for 224 W of heat dissipation in the enclosure thermal budget.
