Its 5.67 % relative throttling factor and 0.0015 H inductance are sized to attenuate harmonic currents from variable-frequency drives or other non-linear loads, keeping distortion off the supply side. The 210 Hz resonant frequency of the filter means it targets the 5th harmonic (250 Hz) region common in 6-pulse rectifier front-ends. The 31.6 A rated current is the continuous thermal limit at 40 °C ambient with Class B insulation. The maximum current of 35.1 A is the overload ceiling — sustained operation above the rated value requires derating. The 20 kvar reactive power rating defines the compensation bank size this reactor is paired with. ## Mounting and connection The 4EP4300-4MS00 measures 0.267 m wide by 0.221 m high by 0.12 m deep. Main circuit connections are via screw-type terminals or tab terminals — no special tooling required. The IP00 rating means it is an open-frame component intended for installation inside a grounded, lockable enclosure. Panel layout must account for the 104.2 W heat dissipation and maintain clearance for airflow.","metaTitle":"SIDAC 4EP4300-4MS00 Filter Reactor, 31.6A, 400V, 3-Phase","metaDescription":"SIDAC 4EP4300-4MS00 3-phase filter reactor, rated 31.6A at 400V AC, 50Hz, 5.67% throttling, IP00, screw/tab terminals.
