What this filter reactor is and what it does
The Siemens SIDAC 4EP3700-6MS00 is a 3-phase filter reactor rated for 400 V AC at 50 Hz, with a rated current of 7.23 A and a maximum current of 8.03 A. Its 7 % relative throttling factor and 0.0077 H inductance are sized to attenuate harmonic currents from variable-frequency drives or other non-linear loads, protecting upstream transformers and switchgear. The IP00 enclosure means it is an open-core assembly intended for installation inside a panel or cabinet — not for washdown or outdoor exposure. Screw-type terminals on the main circuit accept power conductors directly.
Key ratings and what they mean for your panel
The 7.23 A rated current (8.03 A maximum) sets the continuous load this reactor can carry without exceeding a 40 °C ambient temperature rise, per thermal class B.
