Siemens 4EU2732-0CD08-4EA0 Filter Reactor, 50 kVAR, 690 V, I

The Siemens 4EU2732-0CD08-4EA0 is a 3-phase filter reactor rated at 50 kVAR reactive power at 690 V, 50 Hz, with a 5.67% P (short-circuit voltage / impedance) — that percentage determines the voltage drop across the reactor at rated current and governs harmonic attenuation and inrush limiting in the circuit. The 210 Hz resonance frequency (FRES) means this reactor is tuned to suppress the 4th harmonic (200 Hz) and adjacent frequencies, so it is suited for drives or power-factor-correction banks where a 210 Hz trap is called for. The IP00 enclosure (no protection against ingress) and free conductor ends mean it mounts inside a cabinet or panel where the terminations connect directly to busbars or cable lugs — not a standalone outdoor unit.
