The Siemens 4EU2432-0AH80-2CA0 is a 3-phase filter reactor rated 25 kVAR at 400 V, 50 Hz. It's designed to sit between a variable-frequency drive and the line, knocking down harmonic distortion before it back-feeds the plant distribution. The 7 % impedance (P(%):7) is the figure that governs the attenuation — too low and the harmonics pass, too high and you drop voltage across the reactor under load. This one splits the difference for standard industrial drives.
The 189 Hz resonant frequency (FRES(HZ):189) indicates where impedance peaks. Check the system's harmonic profile before committing the BOM line. The ripple voltage spec (RIPPLE VOLT. (%):110 /0 /6 /5) is a multi-condition table; treat the 110 % as the ceiling and design for the 5-6 % range under nominal current. IP00 means no enclosure — this is a panel-mount component, not a standalone cabinet. Screw terminals (TYPE OF TERMINALS:SCREW CONNECTION) accept standard ring or fork lugs; plan for a grounded metal backplate and adequate clearance to adjacent gear. The 40 °C ambient (TA/ISOKL:40 /H) is the rated operating temperature; derate above that per the manufacturer's thermal curve, which isn't in this spec set but is standard practice for iron-core reactors.
Built to EN 61558-2-20, the standard for small reactors and chokes. UL/CSA recognized marks are confirmed in the description — the part carries the >UL/CSA-RECOGNIZED< tag, meaning it's accepted for panel builds in North American markets without a separate field evaluation. No RoHS or REACH statement appears in this record; if compliance documentation is required for your project, request it at quote time.
