Reactor Specs and Application
The Siemens 4EU2732-0FQ08-0AA0 is a three-phase filter reactor rated at 37 kVAR on a 400 V, 50 Hz line, with a 7% impedance (p). The 189 Hz resonant frequency places it in the typical tuning range for 5th harmonic suppression in industrial drives and UPS systems — the most common harmonic order from six-pulse rectifiers. Flat-type terminals simplify bus-bar or cable connection in the panel.
Integration Notes
IP00 enclosure means the reactor is intended for indoor cabinet mounting where the panel provides the environmental seal. The 40 °C ambient rating (TA/ISOKL: 40 /H) covers typical switchgear room conditions; derate above that per the thermal curve. Flat-type terminals accept standard cable lugs — no special tooling needed.
