The Siemens SIDAC 4EU3032-0AN08-1BA0 is a 3-phase filter reactor rated for 72.2 A continuous (80.2 A max) at 400 V AC, 50 Hz. It's a line-reactor / choke designed to sit between the drive and the motor or on the line side of a VFD, limiting harmonic distortion and reducing voltage notching on the supply. The 14% relative throttling factor means it drops about 14% of the line voltage at rated current — standard for moderate harmonic mitigation on 6-pulse drives. The 134 Hz resonant frequency means it's tuned to suppress the 5th and 7th harmonics, the dominant ones from a 6-pulse rectifier.
The 72.2 A rated current and 80.2 A maximum tell you this reactor can handle a 55–75 kW motor on a 400 V drive, depending on the drive's overload profile. The 50 kvar reactive power rating confirms it's sized for that power band. The Class H insulation (180°C rated) gives headroom for the internal temperature rise; the 40°C ambient rating is the standard derating baseline.
At 0.3 m wide, 0.269 m tall, and 0.211 m deep, this reactor takes up a fair chunk of panel floor. The screw/flat-type terminals accept lugs or busbars for the main circuit connections. IP00 means no built-in finger protection — mount it behind a locked door or a guard. The 0.0017 H inductance at 14% throttling is the value you need to match your drive manufacturer's recommended line-reactor size for the motor kW.
