The 0.81 mH inductance with a 4% relative inductive voltage drop is sized for a 35.5 A maximum continuous current (31.95 A rated, 44 A peak). ## Current Ratings and Thermal Class The 35.5 A Ithmax is the thermal current rating at 40 °C ambient. The 31.95 A rated current is the nominal operating point at 4% voltage drop. Total coil power loss is 69 W, with 14.5 W iron-core loss. ## Physical Fit and Connections Footprint is 0.178 m wide × 0.153 m tall × 0.12 m deep. Main circuit connects via screw-type terminals, which accept standard power wiring. The choke is not a DIN-rail device; it bolts to a mounting plate.","metaTitle":"Siemens 4EP3802-0DS00 Commutating Choke, 35.5A, 0.81mH, IP00","metaDescription":"Siemens 4EP3802-0DS00 commutating choke for converters.
