It delivers 50 kvar of reactive power compensation with a relative throttling factor of 5.67% and an inductance of 0.88 mH. The Class H insulation (180°C thermal class per IEC 60085) means the winding can handle sustained elevated temperatures inside a closed panel without accelerated aging — that's the rating that governs real-world duty in a warm enclosure, not just the ambient 40°C figure. The 72 A rated current and 80 A maximum tell you the continuous thermal limit and the short-term overload ceiling. The 5.67% impedance attenuates line notches and limits inrush current. The 210 Hz resonant frequency suppresses the 5th harmonic and above. The IP00 protection class means it's an open-frame component — no enclosure, no drip shield. It mounts inside a cabinet, not on the wall. The flat connector / screw-type terminals accept busbar or cable lugs; plan for a separate terminal block if you need ring-tongue terminations. Dimensions are 0.27 m wide by 0.248 m tall by 0.187 m deep — that's about the footprint of a small contactor, but the 245 W power loss at full load means it needs ventilation clearance around it inside the panel. Don't bury it between two solid barriers.","metaTitle":"Siemens SIDAC 4EU2732-0EA30-1B Filter Reactor, 72A, 480V, 50","metaDescription":"Siemens SIDAC 4EU2732-0EA30-1B filter reactor, 3-phase, 72A rated / 80A max, 480V AC, 50 Hz, 50 kvar, 5.67% throttling, Class H insulation, IP00.
