It is designed to sit between a variable-frequency drive and the motor, smoothing the voltage spikes and limiting the rate of current rise from the drive's PWM output. The 0.00016 H inductance and 11.68 % voltage drop (UK) are sized for a nominal line current of 115.2 A at 575 V AC. The 128 A maximum current is the thermal limit under the rated conditions — the reactor will saturate or overheat if that continuous rating is exceeded. The 3000 Hz rated frequency tells you this reactor is tuned for high-switching-frequency drives (common with IGBT-based VFDs running carrier frequencies in the kHz range), not for 50/60 Hz line reactors. At 0 Hz minimum, it passes DC without blocking, which is expected for an output reactor. IP00 means no enclosure — the reactor is a bare magnetic assembly with flat-type terminals. The 0.35 m width, 0.32 m height, and 0.22 m depth define the footprint for panel layout. Thermal class H (180 °C insulation system per IEC 60085) lets it run hot, but the 281 W coil loss and 221 W iron loss total over 500 W of heat to vent inside the panel — account for that in the thermal budget. The reactor is recognized under UL/CSA per EN 61558-2-20, the safety standard for reactors and power supply units. The 40 °C ambient temperature rating is the maximum surrounding air temperature for full-rated operation — above that, derate per the thermal class H curve.","metaTitle":"SIDAC 4EU3631-0UA00-0A Output Reactor, 128A, 3-Phase, IP00","metaDescription":"SIDAC 4EU3631-0UA00-0A output reactor, 3-phase AC, 128A max, 3000Hz rated frequency.
