The 0.25 mH inductance and 4% relative inductive drop are sized to limit di/dt and reduce commutation notches on the line side of a converter. The 91 A AC maximum current (81.9 A continuous AC rated) and 111.5 A DC rated current tell you the choke can handle the ripple current in a DC link or AC line reactor application. The flat-type terminals accept busbar or cable lugs — plan for a bolted connection, not a plug-in. Thermal class B (130 °C rise) and the combined power loss of 104 W (80 W coil + 24 W iron core) at 40 °C ambient mean the choke needs free air movement or forced ventilation inside the panel to stay within its rating.","metaTitle":"Siemens 4EP4002-8DS00 Commutating Choke, 400V 91A 3-Phase","metaDescription":"Siemens 4EP4002-8DS00 commutating choke for converters. 3-phase, 400V AC, 91A max AC current, 0.25mH, IP00.
