The Siemens 4EU2732-0EB28-0BA0 is a 3-phase filter reactor rated at 50 kVAR, 690 V, 50 Hz, with a 7% p impedance — sized for harmonic filtering or line-side smoothing on industrial AC drives and converters. Screw/flat-type terminals accept standard power lugs. The 7% p impedance is the key figure for drive harmonic mitigation — it limits current distortion and protects upstream switchgear. The 189 Hz resonance frequency (FRES) tells you where the series LC circuit peaks; keep that clear of any dominant harmonic in your system.
IP00 means no ingress protection — mount inside a clean, dry cabinet. The 40°C ambient rating (TA/ISOKL:40 /H) covers most industrial enclosures without derating, but check the thermal curve if ambient exceeds that. Screw/flat-type terminals call for a torque wrench during panel wiring.
