Its rated operational current is 30.6 A, with an inductance of 0.47 mH and a voltage drop (UK) of 9%. This reactor sits between a variable-frequency drive output and the motor cable to limit dv/dt stress, reduce capacitive charging currents in long cable runs, and protect motor windings from reflected wave voltage spikes — a common concern on 400 V and 480 V class drives with cable lengths beyond about 50 meters. Built to EN 61558-2-20 and UL/CSA recognized, it carries Class H insulation (180 °C thermal class per IEC 60085) and is rated for a 40 °C ambient. Total power loss splits between the coil (110 W) and iron core (81.9 W) — roughly 192 W at full load, which must be considered in enclosure thermal calculations for the panel. This is an open-frame (IP00) component with flat-type terminals for the main circuit connections — no DIN-rail clip, no enclosure. It measures 0.22 m wide × 0.21 m high × 0.13 m deep. Mount it on a backplate or chassis inside a panel, with clearance for airflow around the core. The flat terminals accept lug or bus-bar connections; plan for adequate bending radius on the motor cable leads.","metaTitle":"Siemens SIDAC 4EU2431-2UA00-0A Output Reactor, 34A 300Hz 3-P","metaDescription":"Siemens SIDAC 4EU2431-2UA00-0A 3-phase output reactor, 34A max at 300Hz, 575V, 0.47mH.
