The Siemens 4EU3632-0CK00-0BA0 is a Filterdrossel — a three-phase AC line filter choke rated for 810 A continuous at 800 V, with a nominal inductance of 15 µH. It sits on the line side of a drive or inverter to smooth current ripple and limit harmonic content, sized for a 30 Hz fundamental operating frequency. The IP00 open-frame construction means it mounts inside a cabinet, not on a panel surface; plan for a dedicated enclosure bay with forced air or natural convection to handle the combined 400 W power loss (370 W coil + 30 W iron core).
The 810 A rated current at 800 V AC tells you this choke is built for a high-power drive — think 600–700 kW motor loads on a 690 V line. The 15 µH inductance at 30 Hz fundamental is a low-value design, typical for drives that switch at higher carrier frequencies (2–16 kHz) where the choke mainly attenuates switching ripple rather than 50/60 Hz harmonics. The 30 Hz fundamental rating means it's optimized for variable-frequency drives running below 30 Hz output; if your application runs above 30 Hz, check the saturation curve — the core may saturate at higher frequencies. Class H insulation (180 °C rated) gives headroom for the 40 °C ambient and the 370 W coil loss; still, derate if ambient exceeds 40 °C or if the enclosure restricts airflow.
Physical fit and connection
Dimensions are 0.35 m wide × 0.321 m tall × 0.237 m deep — a substantial block, roughly 14 × 13 × 9.3 inches. The main current circuit uses flat connectors (bus-bar style), so you'll need copper bars or braided straps rated for 810 A, not lugged cable. No DIN-rail clip; this choke bolts directly to a backplate or chassis. IP00 means no ingress protection — keep it inside a clean, dry cabinet away from washdown or dust.
