What this filter reactor does in the line
The SIDAC 4EU3032-0MH08-0AA0 is a 3-phase filter reactor rated for 525 V AC at 50 Hz, with a rated current of 37.4 A and a maximum current of 41.5 A. The 14% relative throttling factor and 0.0042 H inductance are sized to attenuate harmonics and limit inrush current on VFD or soft-starter inputs. The resonant frequency sits at 134 Hz, well above the 50 Hz line fundamental, so it avoids self-resonance with the supply. Reactive power of the filter bank is 33.7 kvar.
The 37.4 A rated current (41.5 A max) tells you the continuous load this reactor can carry without saturating the core or exceeding the thermal class H limit at a 40 °C ambient. The 525 V rated voltage matches common 480 V / 500 V industrial systems with headroom for line swells. The 14% throttling factor is the impedance at rated current — typical for line reactors used to reduce harmonic distortion and protect drive input rectifiers. Power loss of 316.8 W means you need to account for heat dissipation in the enclosure; don't bury it in a sealed box without ventilation. The screw/flat-type terminals accept standard lugs or bus bars — no special crimp tool needed.
