The Siemens 4EU3032-3ME08-0AA0 is a three-phase filter reactor rated at 50 kVAR, 480 V, 60 Hz, with a 14% impedance (P(%):14). It is designed to suppress harmonics and limit inrush current in power distribution and drive systems — a line reactor, built to EN 61558-2-20. Termination is via screw/flat-type terminals, which accept standard lug or busbar connections.
The 50 kVAR rating at 480 V gives the reactive power handling. The 14% impedance provides harmonic attenuation but drops voltage under load. The 134 Hz resonant frequency is above the 60 Hz line frequency. The 40 °C ambient rating is the maximum surrounding air temperature for full-rated current.
