Filter Reactor for Harmonic Mitigation
The Siemens 4EU3632-5MB08-0AA0 is a 3-phase filter reactor rated 100 kVAR at 440 V, 60 Hz, with a 7% p impedance — sized for harmonic mitigation on power-factor-correction capacitor banks or drive input stages. The 7% p detuning shifts the resonant frequency below the 5th harmonic (227 Hz resonant frequency per the spec), protecting capacitors from harmonic overload in industrial networks with 6-pulse drives or welding loads.
Electrical Ratings and Duty
Rated reactive power is 100 kVAR at the nominal 440 V, 60 Hz condition. The 7% p impedance (relative to the capacitor bank rating) is the standard detuning factor for 5th-harmonic suppression in 60 Hz systems. The 227 Hz resonant frequency confirms the trap is below the 300 Hz 5th harmonic, so the reactor does not create a parallel resonance at a dominant harmonic order. Ripple voltage parameters (106% at 0.5 A, 6 A, 5 A) describe the voltage distortion the reactor can sustain under specified harmonic current content — relevant for verifying the reactor does not saturate under the expected drive or rectifier current spectrum.
Construction and Compliance
Terminals are screw/tab connection, compatible with ring or fork lugs up to the conductor size the terminal accommodates (verify lug width against the tab dimensions on the nameplate). Designed per EN 61558-2-20 (safety of transformers, reactors, power supply units — particular requirements for small reactors). UL/CSA recognized, which satisfies North American panel inspection requirements for a listed component. The >CHOKE< marking indicates the UL/CSA recognition category for reactor-type devices.
