The Siemens 4EU3631-0BS10-0A is a filter reactor — a line choke — designed to smooth current ripple and limit harmonic distortion on the AC side of a variable-frequency drive or power converter. It's rated for a maximum continuous current of 200 A, with a nominal rating of 180 A at 400 VAC, 60 Hz, three-phase operation. The 0.19 mH inductance value is tuned for ripple suppression in typical PWM drive front-ends.
The 200 A maximum and 180 A rated current tell you this reactor is sized for a drive with a nominal output around 90–110 kW at 400 V — the 180 A figure is the continuous thermal limit under rated conditions. The 0.19 mH inductance and 70% ripple voltage spec (from the description) mean it's designed for a drive with a typical DC-link ripple requirement, not a high-impedance harmonic filter. Thermal class H (180 °C insulation system) and a 55 °C ambient rating give it headroom in warm enclosures; the 593 W total power loss (411 W in the coil, 182 W in the iron core) must be vented — IP00 means no enclosure, so it's intended for a cabinet with forced airflow or natural convection sizing.
This is an open-frame reactor — IP00, no housing — so it mounts inside a cabinet, not on a DIN rail. The flat connector terminals for the main circuit accept busbar or cable lugs; plan for a bolted connection. Dimensions are 0.35 m wide, 0.321 m tall, and 0.227 m deep — it's a substantial block, roughly the footprint of a small suitcase, so verify panel depth and door clearance before laying out the gland plate. Mounting is typically on a baseplate or chassis via the reactor's own foot brackets; no DIN-rail clip here.
