The Siemens 4EU2732-0FT08-1BA0 is a 3-phase filter reactor rated 50 kVAR at 525 V, 50 Hz, with a 5.67% P impedance. It is designed to suppress harmonics and limit inrush currents in power distribution and drive systems, built to EN 61558. Flat-type terminals accept busbar or cable lugs, common in high-current power paths. The 210 Hz resonant frequency (FRES) tells you where the series resonance sits — useful when coordinating with downstream capacitor banks to avoid parallel resonance.
50 kVAR at 525 V sets the reactive power compensation capacity. The 5.67% P (percent impedance) defines the voltage drop at rated current — a standard value for line reactors used with variable frequency drives to reduce harmonic distortion and protect the DC bus. The 40 °C ambient rating (TA/ISOKL:40 /H) is the maximum operating temperature without derating; above that, the reactor must be derated per the thermal curve. Ripple voltage percentages (110 /0 /6 /5) describe the harmonic content the reactor is designed to handle — typically a mix of 5th, 7th, and higher-order harmonics common in 6-pulse rectifier front-ends. The 210 Hz resonant frequency (FRES) is the point where the reactor's impedance peaks; keep downstream filter components away from this frequency to avoid amplification.
Panel integration
IP00 means no ingress protection — mount inside a clean, dry enclosure with adequate ventilation for heat dissipation. Flat-type terminals simplify busbar connection but require proper torque values (not listed here; follow the nameplate or installation manual). The reactor is heavy and generates heat; plan for structural support and clearance from heat-sensitive components.
