What this reactor does for your drive line
The SIDAC 4EP4010-0TK00 is a three-phase output reactor rated for 32 A maximum continuous current, with an inductance of 0.18 mH and a rated frequency range of 6 to 400 Hz. It sits between the VFD output and the motor, smoothing voltage spikes and limiting the rate of rise of voltage (dV/dt) that can damage winding insulation on long cable runs. The 11.1% short-circuit voltage (Uk) tells you the impedance drop at rated current — enough to knock down reflected-wave peaks on 600 V class drives without eating up excessive voltage headroom. The 0.18 mH inductance is sized for a nominal 28.8 A continuous load current (I LN), which matches the 32 A thermal maximum (Ithmax) with a healthy margin. At 6.4 kHz switching frequency (F Takt), the core losses (43.2 W iron) plus copper losses (65.2 W coil) total about 108 W dissipated as heat — plan for that in your enclosure ventilation, especially since the ambient rating is 40 °C and the thermal class is B (130 °C hot-spot).
IP00 means no enclosure — this is a panel-mount component that needs a clean, dry cabinet. Dimensions are 0.21 m wide, 0.17 m tall, 0.14 m deep — a compact block that fits most drive cabinets without a custom bracket.
