It is designed to suppress harmonic currents and limit inrush in power-factor-correction banks or drive DC-link circuits. Flat-type terminals accept busbar or cable lugs, typical for power-distribution assemblies above 100 A. The 45 kVAR reactive-power rating at 480 V tells you the capacitor bank this reactor can protect. The 7 % impedance (P(%):7) is the standard detuning factor for a 189 Hz resonant frequency — that tunes the trap below the 5th harmonic (300 Hz at 50 Hz fundamental), which is the dominant harmonic from 6-pulse drives. The 40 °C ambient rating (TA/ISOKL:40 /H) is the operating limit; above that, derate the kVAR or force-cool the cabinet. Ripple voltage ratings of 110 / 0 / 6 / 5 % likely correspond to different harmonic orders or test conditions per EN 61558-2-20. The 110 % figure is the peak line-frequency overvoltage the reactor can sustain; the lower figures (6 %, 5 %) are harmonic ripple limits at the tuning frequency. In practice, this means the reactor handles the voltage stress from a standard 6-pulse drive without saturating.","metaTitle":"Siemens 4EU2732-0CC08-0BA0 Filter Reactor, 45 kVAR, 480 V, I","metaDescription":"Siemens 4EU2732-0CC08-0BA0 filter reactor, 3-phase, 45 kVAR at 480 V 50 Hz, IP00, flat-type terminals.
