It sits between the VFD and the motor to limit the rate of voltage rise (dV/dt) and reduce capacitive coupling currents in long cable runs. The 10 A maximum current and 0.0003 H inductance define the motor-side filtering it provides. At 8 kHz carrier, it smooths the PWM edges that would otherwise stress motor insulation or cause bearing currents. The 34 W total power loss (10 W coil + 24 W iron core) at 40 °C ambient is what the enclosure around it needs to vent. ## Integration constraints – IP00, terminal type, and thermal class IP00 means no ingress protection: this reactor must live inside a panel or enclosure that provides the environmental seal. Thermal class B per IEC 60085 means the insulation system is rated for a 130 °C continuous hot-spot temperature. The 0.1 m depth, 0.17 m width, and 0.15 m height footprint fits a standard sub-panel layout, but the open frame needs clearance from live parts and grounded metal. Siemens lists the lifecycle stage for the 4EP3700-0LK00 as mature. This typically means the design is stable and the part is in regular production, but it may not be actively promoted for new large-scale projects. No successor order code is published.","metaTitle":"Siemens SIDAC 4EP3700-0LK00 Output Reactor, 3-Phase, 8 kHz,","metaDescription":"Siemens SIDAC 4EP3700-0LK00 output reactor, 3-phase AC, 8 kHz rated frequency, 10 A max, IP00.
