The 40 A rating is the thermal limit at 40 °C ambient; the reactor's total power loss (coil 26.3 W plus iron core 65.2 W) sums to 91.5 W, which must be dissipated in the enclosure. IP00 means no ingress protection — it requires mounting inside a clean, dry cabinet, not in a washdown or outdoor location. ## Deployment context This output reactor mounts via its screw-type terminals (main circuit connection) and sits between a variable-frequency drive output and the motor cable. The 0.21 m width, 0.17 m height, and 0.14 m depth define the panel footprint — allow clearance around the IP00 body for airflow to carry off the 91.5 W total loss. Thermal class B insulation (130 °C continuous) per IEC 60085 means the winding can sustain that temperature rise without degrading the insulation system. The 4EP4011-0AK00 carries a mature lifecycle stage — it is not in active new-product introduction but remains in the Siemens SIDAC catalog as a standard production item. No official successor order code has been published, so the BOM line stays stable for existing designs.","metaTitle":"Siemens SIDAC 4EP4011-0AK00 Output Reactor, 40A 3-Phase AC","metaDescription":"Siemens SIDAC 4EP4011-0AK00 output reactor, 3-phase AC, 40A max, 4 kHz switching frequency, 0.2 mH, IP00, screw terminals.
