The Siemens 4EU3632-0CL00-0BA0 is a three-phase AC filter choke (Filterdrossel) rated for 810 A continuous and 800 V operating voltage. That 810 A figure governs the main circuit — this is the current it carries without saturating the core, so it's sized for the line side of a large drive or converter, not a motor branch. Inductance is 15 µH at 30 Hz operating frequency — a low-value line choke meant to limit di/dt and reduce harmonic distortion on the supply side, not a DC-link smoothing reactor. The 40 °C ambient rating is the design point; thermal class H insulation (IEC 60085) means the winding can handle sustained 180 °C hot-spot temperature without degrading.
Total power loss is 370 W in the coil plus 30 W in the iron core. At IP00, the choke relies on the cabinet's forced-air or natural convection to stay within the thermal class H limit. Physical footprint is 0.35 m wide × 0.321 m tall × 0.237 m deep. The flat-type connector for the main circuit suggests busbar or heavy cable lugs, not screw terminals — plan the connection method before the choke arrives on site.
