What this output reactor does in the drive line
The SIDAC 4EU3052-0ED00-4CA0 is a 3-phase AC output reactor — an output choke — rated for 60 A maximum current and 54 A operational current at 40 °C ambient. It sits between the VFD output and the motor cable, limiting the rate of voltage rise (dV/dt) and reducing reflected-wave peaks on long cable runs. The 0.35 mH inductance and 17.1 % impedance (UK) at 600 Hz switching frequency are sized for a 4 kHz carrier, which is the typical PWM frequency range for general-purpose drives driving induction motors on conveyors, pumps, or fans.
Mounting and integration — IP00, screw terminals, panel fit
The 0.3 m width, 0.26 m height, and 0.21 m depth define the footprint on the panel backplate or DIN-rail mounting plate. Screw-type terminals accept lugged cable for the main power circuit; plan for a minimum bending radius on the incoming and outgoing motor cables. Thermal class H insulation means the winding can sustain 180 °C hot-spot temperature — derate the 54 A operational current if the cabinet ambient exceeds 40 °C.
Combined power loss is 225 W — 120 W in the coil (copper losses) plus 105 W in the iron core (hysteresis and eddy-current losses). That heat must be evacuated from the enclosure; a panel fan or forced ventilation is expected for any cabinet housing this reactor alongside a drive. The 40 °C ambient rating is the reference point; above that, derate the operational current per the thermal curve in the full datasheet.
