The Siemens SIDAC 4EU2732-0BC08-1BA0 is a three-phase filter reactor rated for 65.3 A continuous with a 72.6 A maximum, 525 V AC, 50 Hz, and 50 kvar reactive power. It carries a 5.67% relative throttling factor and 0.0011 H inductance, designed to attenuate harmonic currents and limit inrush on VFD line inputs or power-factor-correction banks.
The 65.3 A rated current and 72.6 A maximum define the thermal limit under continuous load at 40 °C ambient — size the upstream protection to the rated value, not the peak. The 525 V operating voltage suits 400/480 V line-to-line systems with margin; the 50 Hz rating is fixed, so a 60 Hz application would shift the resonant frequency and derate the core.
Integration notes
Dimensions: 0.187 m depth, 0.27 m width, 0.248 m height. Main circuit connection uses flat connector / screw-type terminals — expect a lug or bus-bar interface, not a plug-in. Thermal class H (IEC 60085) means the winding insulation withstands 180 °C hot-spot temperature, adequate for high-ambient panels or enclosed mounting. Power loss is 262 W at rated load, so account for that heat in the enclosure ventilation.
