It sits between the VFD output and the motor cable, limiting the rate of voltage rise (dV/dt) and reducing capacitive charging currents in long cable runs. The 0.075 mH inductance per phase and 6.15 % impedance (UK) at 400 V are sized for a 54 A nominal line current (I LN) — so the reactor is matched to a drive that delivers about 54 A continuous, with headroom to 60 A for short-duration overloads. ## Thermal and mounting reality The combined copper and iron losses total 86.8 W (52.5 W coil + 34.3 W iron core) at the rated 40 °C ambient, so the panel designer needs to account for that heat rise. Thermal class B (130 °C winding temperature limit) is standard for general-purpose industrial reactors. The flat-type terminals accept busbar or cable lug connections — no screw-clamp terminals here, so plan for a bolted connection.","metaTitle":"Siemens SIDAC 4EP3801-1DK00 Output Reactor, 60A, 8 kHz","metaDescription":"Siemens SIDAC 4EP3801-1DK00 3-phase output reactor, 60A max, 8 kHz switching frequency, 0.075 mH.
