It's the kind of component you spec between a variable-frequency drive and the motor to knock down harmonics and limit current spikes — out here in the grease, that's what keeps a bearing from taking a hit from reflected waves on a long cable run. The 14% relative throttling factor (0.0033 H inductance) tells you it's tuned for moderate harmonic suppression, not a full clean-up. Mounting is panel-mount only — it's IP00, so no enclosure, no splash protection. That means it belongs inside a cabinet, away from washdown or outdoor weather. The screw-type terminals on flat connectors handle the main circuit wiring; expect to land lugs or fork terminals on these. The 34.6 A rated current is the number that decides panel fit. This reactor is sized for a drive output around that ampacity — think a 22 kW motor at 400 V, give or take, depending on duty cycle. The 38.5 A maximum gives a little headroom for overload, but don't plan on running it there continuously. Thermal class H (180 °C rated insulation) means the windings can take sustained heat. That's important when the reactor sits near a drive that's dumping heat into the cabinet. At 210 W power loss, it's not a cool part — plan ventilation or keep it away from temperature-sensitive controls. Dimensions are 0.27 m wide, 0.248 m tall, and 0.187 m deep. That's a substantial block — about the size of a shoebox on its side. Leave clearance around it for airflow and the screw-terminal access on the flat connectors. It's not a DIN-rail clip-in; you bolt it to a backplate.","metaTitle":"Siemens SIDAC 4EU2732-0MB08-4CA0 Filter Reactor, 34.6A, 400V","metaDescription":"Siemens SIDAC 4EU2732-0MB08-4CA0 filter reactor, 34.6A rated, 400V AC, 3-phase, 50Hz.
