What this reactor does for your drive line
The SIDAC 4EU2452-0EG00-4BA0 is a 3-phase output reactor rated for 25 A maximum and an 8 kHz switching frequency, with 0.1 mH inductance. It sits between the VFD output and the motor to limit the rate of voltage rise (dV/dt) and reduce reflected-wave stress on motor insulation — critical on long cable runs or when feeding older motors with Class H thermal class insulation per IEC 60085.
Rated for 480 V AC input (UN1), the reactor handles a continuous line current of 22.5 A (I LN) with a short-term maximum of 25 A. The 8 kHz switching frequency matches modern IGBT-based drives; if your drive runs a lower carrier, the reactor still works — the inductance is fixed. Power losses split between the coil (36 W) and the iron core (87 W), totalling 123 W at rated load, so factor that heat into your panel's thermal budget. Ambient temperature rated at 40 °C; derate above that per the thermal curve. The flat-type terminal connection suits busbar or large-crimp lugs — not spring-cage or screw-clamp. Verify your cable lug width against the 0.22 m width of the housing before terminating.
