The Siemens 4EU3032-0FN08-4BA0 is a 3-phase filter reactor rated at 50 kVAR, 690 V, 50 Hz, with 14 % impedance. It's designed to sit between a variable-frequency drive and the motor, or on the line side of a drive, to smooth out harmonic currents and limit voltage notching. The 14 % impedance figure is the key selection parameter — that's the ratio of the reactor's inductive voltage drop to the rated voltage at rated current, and it tells you how much harmonic attenuation you're getting. For a 690 V drive system, this is a heavy-duty line reactor, not a light-duty choke.
The 50 kVAR rating at 690 V and 50 Hz defines the reactive power compensation capability. The 14 % impedance (P(%):14) is the standard choice for drives applications — it provides enough inductance to limit di/dt and reduce harmonic distortion without dropping excessive voltage under load. The 134 Hz resonant frequency (FRES(HZ):134) tells you where the reactor's impedance peaks; keep that well away from any system harmonics you expect (e.g., the 5th, 7th, 11th) to avoid resonance. The IP00 enclosure means it's an open-style reactor for installation inside a cabinet — no drip shield, so it needs a clean, dry environment. Flat-type terminals (TYPE OF TERMINALS:FLAT-TYPE TERMINAL) accept busbar or large cable lugs, typical for panel builders wiring 690 V drives.
Designed to EN 61558, the safety standard for power transformers, reactors, and power supply units. This covers electrical, thermal, and mechanical safety requirements for the reactor itself.
