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 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.
