It provides 7 % relative throttling factor (0.0026 H inductance) to attenuate harmonic currents and limit inrush on variable-frequency drives or power-factor-correction banks. The 14 600 var reactive-power rating tells you the capacitor bank size it's designed to work with — match the reactor to the bank's kvar, not just the line current. Rated 23.5 A with a 26.1 A maximum — the continuous current the reactor can carry without exceeding Class B (130 °C) temperature rise at 40 °C ambient. The 7 % impedance is the standard detuning factor for 5th-harmonic suppression in 50 Hz networks. Resonant frequency sits at 189 Hz, well clear of the 250 Hz 5th harmonic, so the series LC circuit stays below the tuning point and doesn't amplify harmonics. Power loss is 113 W at full load; factor that into your enclosure ventilation budget. ## Deployment context IP00 — no enclosure protection — so this reactor mounts inside a panel or cabinet, not in a washdown or outdoor location. The screw-type and tab terminals accept lug or fork terminations for the main circuit. Dimensions are 0.267 m wide by 0.221 m tall by 0.12 m deep; plan for that footprint plus clearance for airflow and terminal access.","metaTitle":"SIDAC 4EP4300-0EP00 Filter Reactor, 23.5 A, 400 V, 3-Phase","metaDescription":"SIDAC 4EP4300-0EP00 3-phase filter reactor rated 23.5 A at 400 V AC, 50 Hz, 7% throttling factor, IP00.
