It is designed for series connection with a capacitor bank to form a harmonic filter circuit, blocking the dominant 189 Hz resonant frequency from propagating back onto the supply. Flat-type terminals accept busbar or cable lugs for high-current power connections. The 75 kVAR rating at 690 V defines the reactive power the reactor can handle continuously at its fundamental frequency. The 7% detuning factor (p=7%) shifts the filter's resonant point below the 5th harmonic (250 Hz at 50 Hz fundamental), which is the standard choice for suppressing 250 Hz harmonic currents from 6-pulse drives. The listed resonant frequency of 189 Hz (Fres=189 Hz) confirms this — it sits between the 3rd (150 Hz) and 5th (250 Hz) harmonics, avoiding amplification of either. The ripple voltage percentages (106% / 0.5 / 4.8 / 4.8) describe the voltage distortion limits across the reactor under specified harmonic load conditions; the 106% figure is the peak ripple voltage relative to fundamental, and the remaining values likely correspond to specific harmonic orders or test points per EN 61558-2-20. The IP00 rating means the reactor has no enclosure — it is a bare magnetic assembly with flat-type terminals. Mount it inside a clean, dry cabinet with adequate clearance for heat dissipation. The 40°C ambient rating (TA/ISOKL:40 /H) is the maximum surrounding air temperature for full-load operation; above that, derate the kVAR handling per the manufacturer's thermal curve. Flat-type terminals are designed for bolted busbar or cable-lug connections — torque to the value specified on the nameplate. Verify that the cabinet's gland plate has enough fill-factor room for the incoming and outgoing power cables, as the reactor's physical footprint and terminal orientation dictate cable routing.","metaTitle":"Siemens 4EU3032-0AU08-0AA0 Filter Reactor, 75 kVAR, 690 V, 5","metaDescription":"Siemens 4EU3032-0AU08-0AA0 filter reactor, 3-phase, 75 kVAR, 690 V, 50 Hz, 7% detuning, IP00, flat-type terminals.
