3-Phase Filter Reactor, 25 kVAR, 590 V, 50 Hz
The Siemens 4EU2432-0EL00-4CA0 is a 3-phase filter reactor rated for 25 kVAR at 590 V, 50 Hz, with a 7% impedance and a resonant frequency of 189 Hz. Built to EN 61558-2-20, it serves as a line-reactor choke in power-quality and harmonic-mitigation applications — typically placed between a drive and the supply to limit current rise and reduce harmonic distortion. The IP00 rating means it is an open-frame component intended for installation inside a cabinet or enclosure, not for standalone outdoor use. Termination is via screw connections, which suits panel wiring practices where ring or fork terminals are preferred over bus-bar clamps.
The 25 kVAR rating at 590 V defines the reactive-power compensation capacity — this reactor is sized for a specific harmonic filter bank or drive input section, not a general-purpose line choke. The 7% impedance (P(%):7) is the per-unit voltage drop at rated current, which governs how much harmonic attenuation the reactor provides; 7% is a common choice for 6-pulse drive front ends to meet IEEE 519-2014 guidelines. The 189 Hz resonant frequency tells you where the reactor's impedance peaks — important when tuning a filter to avoid resonance with downstream capacitor banks or system harmonics. The 40 °C ambient rating (TA/ISOKL:40 /H) is the maximum operating temperature; derate current above that.
The IP00 enclosure means this reactor must be mounted inside a cabinet with appropriate clearance for airflow and creepage distances. Screw terminals accept standard ring or fork lugs; torque values per Siemens installation instructions. The 40 °C ambient rating governs the thermal design of the enclosure — ensure adequate ventilation or forced cooling if the cabinet ambient exceeds that. No DIN-rail clip is specified; expect foot-mounting on a panel or chassis base.
