The SIDAC 4EU3032-0MB08-0AA0 is a 3-phase filter reactor rated for 69.2 A continuous with a 76.9 A maximum, sized for 400 V AC 50 Hz line supplies. The 14 % relative throttling factor means it drops about 14 % of line voltage at rated current — typical for reducing harmonic distortion and limiting inrush on variable-frequency drives. The 50 kvar reactive power rating tells you the reactor's volt-ampere reactive capacity at the fundamental frequency; match it to the drive's input rectifier stage to keep total harmonic distortion (THD) within IEC 61000-2-4 limits. The 0.0017 H inductance and 134 Hz resonant frequency mean this reactor is tuned to suppress the 5th and 7th harmonics common in 6-pulse drive front ends. Thermal class H (180 °C insulation) and the 337 W power loss figure let you size the enclosure ventilation — at full load the reactor dumps about 337 W as heat, so the panel's cooling must handle that without exceeding the 40 °C ambient rating. The flat connector / screw-type terminals accept busbar or cable lugs; plan for the 0.211 m depth, 0.3 m width, and 0.269 m height when laying out the mounting plate.
This filter reactor mounts on the line side of a 3-phase drive, between the mains disconnect and the drive input. The 0.3 m width and 0.269 m height fit a standard 800 mm wide enclosure with room for side cable ducts. The 0.211 m depth leaves clearance for the rear panel or backplate. Use the flat-type screw terminals for busbar connection; torque to the manufacturer's specification for the lug size chosen.
