The 0.31 mH inductance at 4% relative inductive voltage drop means it's sized for a specific converter power range; swap in a different inductance value and the voltage drop changes, which shifts the drive's DC bus voltage under load. ## Mounting and environment — the gotchas IP00 — no enclosure. The flat-type terminals on the main circuit expect a bolted bus-bar or flat-cable connection; no screw-clamp or spring-cage here. Dimensions are 0.219 m wide × 0.179 m tall × 0.143 m deep — about the footprint of a small shoe box. Thermal class B (130 °C winding rise) with 80 W copper loss and 24.9 W iron-core loss at rated load means it runs hot; cabinet ventilation or forced airflow is expected at the 40 °C ambient rating.","metaTitle":"Siemens 4EP4002-7DS00 Commutating Choke, 400V 3-Phase 71A","metaDescription":"Siemens 4EP4002-7DS00 commutating choke for 3-phase AC converters.
