The Siemens SIDAC 4EU3032-0MG08-0AA0 is a 3-phase filter reactor, rated 98.3 A at 480 V AC, 60 Hz. It delivers 80 kvar of reactive power and carries a 7% relative throttling factor, meaning it smooths line harmonics and limits inrush current for drives and other non-linear loads. Thermal class H (IEC 60085) means the winding insulation handles sustained heat up to 180 °C — built for continuous duty in a closed cabinet.
IP00 means it's an open-frame reactor — no enclosure, no washdown rating. It mounts inside a ventilated electrical panel, not on the floor or outdoors. Terminals are flat-type screw connectors, so you'll land lugs or fork terminals, not spring cages. Dimensions: 0.3 m wide, 0.269 m tall, 0.211 m deep — measure your panel depth before committing.
The 109 A maximum is the peak current the reactor can handle without saturating; the 98.3 A rated value is the continuous design point at 40 °C ambient. The 0.00058 H inductance at 60 Hz gives the 7% impedance that limits harmonic currents. Resonant frequency of 227 Hz means it's tuned to avoid resonance with the drive's switching frequency in most 6-pulse applications.
