The Siemens 4EU2422-8AA00-0AA0 is a 3-phase commutating choke for converter applications, rated 500 V AC with an AC maximum current of 80 A and a DC rated current of 98 A. The IP00 enclosure means it is an open-frame component for cabinet mounting, not standalone outdoor use.
The 80 A AC maximum current (at 50 Hz) and 72 A AC rated current define the continuous thermal limit under sinusoidal conditions; the 98 A DC rated value covers the DC-link current the choke sees in a typical 6-pulse converter. Thermal class H (180 °C hot-spot) per IEC 60085 means the winding insulation can handle sustained high temperatures — relevant if the cabinet ambient hits 40 °C (the rated ambient temperature) and the choke is running near its full current. The 120 W coil loss plus 42 W iron core loss total 162 W of heat to vent inside the panel; factor that into your enclosure's thermal budget. Flat-type terminals (bus-bar style) accept lugs or copper bars, not wire ferrules — plan the main circuit connections accordingly.
Physical integration
Dimensions are 0.225 m wide, 0.21 m high, and 0.136 m deep — a substantial block that needs dedicated mounting space in the panel, not a DIN-rail clip-on. The IP00 protection class means no enclosure of its own; mount it where live parts are inaccessible during operation, or provide supplementary guarding. The flat-type main circuit terminals are designed for bolted connections; torque them per Siemens' recommended values (not listed here, but standard for M8 or M10 bus-bar hardware).
