It is designed to sit between a variable-frequency drive output and the motor, smoothing the PWM voltage spikes and limiting the rate of voltage rise (dV/dt) that can stress motor winding insulation over long cable runs. The 171 A maximum current is the thermal limit under the specified conditions — it governs the largest motor load this reactor can handle continuously without saturating the core or exceeding the 401 W coil loss and 221 W iron-core loss. The 3000 Hz rated frequency tells you this reactor is wound for high-switching-frequency drives (common in modern IGBT-based VFDs), not for 50/60 Hz line reactors. At 0.11 mH, the impedance at 3000 Hz is about 2.07 Ω, which provides meaningful dV/dt reduction for a drive switching at 3 kHz or higher. The IP00 protection class means it is an open-frame component — no enclosure, no drip shield. The 40 °C ambient temperature rating and class H insulation (thermal class per IEC 60085) mean the winding can tolerate a 180 °C hot-spot temperature, giving headroom in warm panels or when the reactor is loaded near its maximum. ## Where and how it is used This output reactor is typically wired between the drive output terminals and the motor cable, inside the drive cabinet or a separate enclosure. The flat-type terminals accept busbar or cable lugs — no screw-clamp connectors, so plan for bolted connections. The 0.35 m width and 0.32 m height mean it takes up a fair amount of panel real estate; account for clearance around the terminals and for airflow over the core and coils. That recognition is tied to the specific design and winding construction — verify the nameplate marking matches your panel's listing requirements.","metaTitle":"Siemens SIDAC 4EU3631-1UA00-0A Output Reactor, 171A, 3000 Hz","metaDescription":"Siemens SIDAC 4EU3631-1UA00-0A output reactor, 3-phase, 171A max, 3000 Hz, 0.11 mH.
