The 4000 Hz rated switching frequency and 8000 Hz maximum tell you this reactor is wound for IGBT drives running PWM carrier frequencies in that range — common on modern VFDs for reduced motor audible noise. The 1 mH inductance and 4% short-circuit voltage (Uk) are sized to limit the rate of rise of current from the drive's output pulses, protecting the motor windings from reflected-wave voltage spikes on longer cable runs. Dimensions are 0.17 m wide, 0.15 m tall, and 0.12 m deep — roughly 170 × 150 × 120 mm. At IP00, it requires a clean, dry enclosure; no dust or conductive debris should reach the windings. The 30.7 W coil loss plus 15 W iron core loss means about 46 W total heat to dissipate inside the panel — account for that in your thermal budget.","metaTitle":"Siemens SIDAC 4EP3806-0BS01 Output Reactor, 3-Phase, 4 kHz","metaDescription":"Siemens SIDAC 4EP3806-0BS01 3-phase output reactor, 1 mH, 9 A, 4000 Hz switching frequency, IP00, screw terminals.
