What It Is and What It Does
The Siemens 4EU2732-0GA08-0AA0 is a 3-phase filter reactor rated at 50 kVAR, 600 V, 60 Hz with a 7% impedance (p). It's built to EN 61558-2-20, the standard for reactors and power supply units. The IP00 enclosure means it's an open-frame component — intended for installation inside a cabinet or panel where it's protected from dust and moisture. Terminals are flat-type, which simplifies bus-bar or cable lug connections in a power distribution assembly.
Key Ratings and What They Mean for Fit
The 50 kVAR rating tells you this reactor is sized for a capacitor bank or harmonic filter bank of that reactive power — it's not a general-purpose line reactor for a single drive. The 7% impedance (p) is the typical value for a detuned reactor used to shift the resonant frequency away from the 5th and 7th harmonics, protecting capacitors from overcurrent. The 189 Hz resonant frequency (FRES) confirms it's tuned for a 60 Hz system with a 7% p reactor — that puts the trap below the 5th harmonic (300 Hz), which is the standard approach for industrial power factor correction.
