Its 0.3 mH inductance (LN) and 9.2% impedance (UK) are sized to limit the rate of voltage rise (dV/dt) and peak currents from a VFD's PWM output, protecting the motor windings and extending cable runs. The 4EP3804-2BK00 is designed for a 3-phase AC output from a variable-frequency drive, not a line reactor. The 6.4 kHz rated frequency matches the typical switching frequency of many modern IGBT-based drives — if your drive's carrier frequency is set to 4 kHz or 8 kHz, this reactor still works, but the core losses and temperature rise will differ. The 0.3 mH inductance and 17 A rating pair with a motor load of roughly 15.3 A (I LN), which is the nominal current the reactor is optimized for at 40°C ambient. ## Integration notes Dimensions are 0.17 m wide, 0.15 m tall, and 0.12 m deep — a compact block that fits on a standard backplate or DIN-rail adapter plate. Connection is via screw-type or tab terminals for the main circuit, so no special crimp tooling is required. The Class B insulation system (130°C) and 40°C ambient rating are standard for general-purpose industrial environments.","metaTitle":"Siemens SIDAC 4EP3804-2BK00 Output Reactor, 17A 6.4 kHz","metaDescription":"Siemens SIDAC 4EP3804-2BK00 3-phase output reactor, 17A max, 6.4 kHz rated frequency, 0.3 mH.
