The Siemens 4EU3032-0FD08-0AA0 is a three-phase filter reactor rated for 47 kVAR at 525 V and 50 Hz, with an 8% p impedance. It's built to EN 61558-2-20 (choke standard) and comes as an open-frame IP00 unit with flat-type terminals — meaning it's a panel-mount component, not a standalone enclosure. The 177 Hz resonant frequency tells you where it's tuned to suppress harmonics, typically on the line side of a VFD or a power-factor correction bank.
IP00 and flat-type terminals mean this reactor lands inside a cabinet, not on a wall. The flat terminals accept busbar or lug connections — typical for a power-distribution or drive-input section. The 177 Hz resonant frequency suggests it's tuned for a 6-pulse rectifier front end (common in VFDs), so mount it close to the drive's line input to keep harmonic currents out of the upstream transformer.
