The SIDAC 4EU3032-1MB08-0AA0 is a 3-phase filter reactor rated for 69 A continuous with a 77 A maximum, operating at 480 V AC and 60 Hz. It delivers 50 kvar of reactive power with a 5.67 % relative throttling factor and 0.74 mH inductance. The reactor is built to thermal class H per IEC 60085, meaning the winding insulation handles the sustained heat a cement plant or heavy industrial panel throws at it—rated for the heat, not the office. IP00 protection means it is an open-frame component intended for inside a ventilated enclosure, not exposed to dust or washdown.
The 69 A rated current and 77 A maximum tell you the reactor is sized for a drive or power system whose fundamental current stays under 69 A continuous, with short-term overloads up to 77 A. The 5.67 % relative throttling factor means the reactor drops about 5.67 % of line voltage at rated current—enough to limit harmonic distortion and reduce dV/dt stress on the drive DC bus, but not so high that it sags the motor voltage under load. A 252 Hz resonant frequency places the reactor's self-resonance above the dominant harmonics (5th, 7th) in a 6-pulse drive, so it attenuates those harmonics without amplifying switching noise.
The reactor measures 0.3 m wide by 0.269 m tall by 0.211 m deep. It uses flat connector / screw-type terminals for the main power connections—common on line reactors in the 69 A class, so standard ring or fork lugs mate directly. Because it is IP00, plan for a clean, dry, ventilated enclosure; the reactor dissipates 301 W at rated load, so forced airflow or generous natural convection is needed to keep the core temperature within the class-H insulation limit.
