Filter reactor for harmonic mitigation
The Siemens 4EU3032-0MS08-1BA0 is a 3-phase filter reactor rated 70 kVAR at 400 V 50 Hz with a 7% p impedance. The IP00 enclosure means it's an open-frame component intended for cabinet mounting — plan for proper clearance and cooling airflow around it.
The 70 kVAR at 400 V 50 Hz tells you the reactive power compensation this reactor can handle in a tuned filter bank. The 7% p (percent impedance) sets the detuning frequency — at 189 Hz resonant frequency (FRES(HZ):189), it's tuned to suppress the 5th harmonic (typically 250 Hz on a 50 Hz system) while presenting a low-impedance path at the fundamental. The ripple voltage spec (110 /0 /6 /5) describes the voltage distortion limits the reactor can withstand across its terminals under rated conditions.
Termination and mounting
Flat-type terminals accept busbar or cable lugs — no ring-tongue crimp needed. The IP00 rating means no integral enclosure; mount it inside a cabinet with at least IP2X protection on the panel door. The 40 /H thermal class (TA/ISOKL:40 /H) indicates a 40 °C ambient with a 100 K temperature rise limit, so derate if your enclosure ambient runs hotter.
