Its 3 kHz switching frequency rating means it is designed to sit between a PWM drive and the motor cable, limiting the rate of voltage rise (dV/dt) and reducing reflected-wave peaks that can cause premature motor insulation failure on long cable runs. The reactor's 0.008 mH inductance and 1.15 % impedance (UK) are sized for motor protection, not line filtering — the voltage drop across the reactor stays low enough that the motor sees near full line voltage under load. Per the datasheet, this is a UL/CSA-recognized component under EN 61558-2-20, so it carries the approvals needed for panel builds destined for North American or European installations. The reactor dissipates 293 W in the coil and 175 W in the iron core at rated load, for a total of 468 W that must be vented out of the enclosure. Thermal class H per IEC 60085 means the insulation system is rated for a 180 °C hot-spot temperature, which gives headroom under the 40 °C ambient rating — but the open frame (IP00) requires forced airflow or a cabinet fan to keep the core temperature within the rise limits. Dimensions are 0.3 m wide by 0.26 m high by 0.21 m deep. The flat-type terminals accept busbar or large-lug connections typical of a 510 A circuit; plan for cable bending radius and clearance around the terminals for a torque wrench.","metaTitle":"Siemens SIDAC 4EU3031-3UA00-0A Output Reactor, 510A, 3 kHz","metaDescription":"Siemens SIDAC 4EU3031-3UA00-0A output reactor, 3-phase, 510A max, 3 kHz switching frequency, 460V, IP00.
