It sits between the VFD and the motor to limit the rate of voltage rise (dV/dt) and reduce reflected-wave peaks on long cable runs — common on 400 V AC drives feeding motors 50+ meters from the drive cabinet. The 8 kHz switching frequency matches the typical IGBT carrier frequency of modern general-purpose drives; if your drive runs a higher carrier (12 or 16 kHz), this reactor still attenuates but the core losses climb. Rated ambient is 40 °C with Class B insulation (130 °C rise), so it handles a warm enclosure without derating as long as airflow is reasonable. ## Mounting and integration — IP00, flat terminals, panel fit IP00 means no enclosure — this is an open-chassis component intended for a cabinet. The flat-type terminals accept busbar or cable lugs; plan for a proper gland plate and strain relief on the incoming motor cable. Dimensions are 0.17 m wide × 0.15 m tall × 0.12 m deep, so it fits a standard 200 mm deep enclosure but leaves tight clearance for the cable bend radius on the output side. Total power loss is 72.9 W (51.6 W coil + 21.3 W iron core) — that heat stays inside the panel, so factor it into your thermal budget. Mount it close to the VFD output; long leads between drive and reactor defeat the purpose.","metaTitle":"Siemens SIDAC 4EP3804-2AK00 Output Reactor, 60A, 8 kHz","metaDescription":"Siemens SIDAC 4EP3804-2AK00 3-phase output reactor, 60A, 8 kHz switching frequency, 0.14 mH, IP00.
