The Siemens 4EU3022-0EE00-1BA0 is a three-phase mains choke — a line reactor — designed to sit between the supply and a variable-frequency drive (VFD). Its job is to knock the edge off line-side harmonics, limit inrush current, and protect the drive's DC bus from supply transients. At 160 A maximum / 144 A rated current on 400 V AC, it's sized for a VFD feeding a motor load in that current class — think a 75–90 kW induction motor on a conveyor or pump. The 0–50 Hz operating frequency range covers the line side; this isn't a load-side output choke. Thermal class H per IEC 60085 means the winding insulation handles 180 °C hot-spot temperature, so it can live in a warm cabinet without derating prematurely. IP00 means no enclosure — it's a bare choke, so it mounts inside a panel where the cabinet door keeps hands and dust out. Terminals are flat-type connectors, sized for the lugging tool on the van. Dimensions: 0.3 m wide, 0.269 m tall, 0.221 m deep — check your gland-plate clearance before committing the panel layout.
The lifecycle stage is marked mature — this part is not in active phase-in or phase-out, but it's an established catalog item. No official successor or last-time-buy date is on record.
