It sits between the VFD output and the motor leads, smoothing the PWM edges and limiting the rate of voltage rise (dV/dt) that can stress motor winding insulation on long cable runs. The 0.16 mH value is sized for the 51 A path — enough inductance to knock down reflected-wave peaks on cable lengths typical of conveyor, pump, or fan drives without dropping excessive voltage across the reactor at rated load. IP00 rating means open-chassis component. Screw-type terminals accept power wiring directly. Thermal class B insulation keeps 48 W coil loss plus 28 W iron-core loss within 40 °C ambient. The 51 A maximum is the thermal current rating at 40 °C ambient — continuous, not intermittent. The 4000 Hz switching-frequency ceiling matches modern IGBT-based drives running 4 kHz PWM; if your drive runs 8 kHz or 16 kHz, this reactor still works but the core losses climb and you should derate the current or improve cabinet airflow. The 0.16 mH inductance is a moderate value — enough to protect a 45.9 A rated motor (the I LN figure from the spec string) on cable runs up to about 50-75 m, depending on cable capacitance. The 7.6 % impedance (UK) at line frequency tells you the voltage drop at full load is modest enough to leave torque on the shaft. Total power loss sums to 76 W (48 W coil + 28 W iron core) at rated conditions. That is heat that stays inside the panel — factor it into your cabinet thermal budget. The 0.12 m depth, 0.17 m width, and 0.15 m height footprint is compact enough for a standard 600 mm deep enclosure, leaving room for the drive above and the motor terminals below. IP00 chassis mounts to a sub-panel or DIN-rail bracket.","metaTitle":"Siemens SIDAC 4EP3800-1PS00 Output Reactor, 51A, 0.16mH, 400","metaDescription":"Siemens SIDAC 4EP3800-1PS00 3-phase output reactor. 51A max, 0.16 mH, 4000 Hz switching frequency.
