That 7% detuning shifts the resonant frequency away from the 5th harmonic — the dominant one from six-pulse drives — so the reactor and capacitor bank don't form a parallel resonance that amplifies harmonics. The 189 Hz resonant frequency (FRES(HZ):189) confirms it's tuned to block the 3.78th harmonic, which is standard for 7% detuned filter circuits in 50 Hz networks. Screw terminals (TYPE OF TERMINALS:SCREW CONNECTION) are straightforward for panel wiring; no special crimp tooling needed. The 12.5 kVAR rating at 400 V tells you the capacitor bank this reactor is paired with: a 12.5 kVAR capacitor at 400 V. The 7% detuning is the standard choice for mitigating 5th and 7th harmonics from six-pulse drives in industrial networks. If your drives are 12-pulse or active front-end, you might not need this — but for a standard VFD line-up, this is the right reactor. The ripple voltage spec (RIPPLE VOLT. (%):110 /0 /6 /5) describes the voltage drop across the reactor at rated current under different harmonic conditions. The 40 °C ambient rating is standard for panel-mounted gear. EN 61558 is the standard for power transformers, reactors, and similar magnetic components — it covers safety, thermal performance, and short-circuit withstand. That certification means the reactor meets European safety requirements for installation in industrial control panels.","metaTitle":"Siemens 4EP4011-0ES00 Filter Reactor, 12.5 kVAR, 400 V, 50 H","metaDescription":"Siemens 4EP4011-0ES00 filter reactor, 3-phase, 12.5 kVAR, 400 V, 50 Hz, 7% detuning, IP00, screw terminals.
