Peak current capability is 100 A — useful for short-duration overloads during motor acceleration or converter inrush. DC-side rated current is 98 A, reflecting the choke's ability to handle the rectified output current. ## Thermal and mounting reality IP00 means no enclosure — this is a panel-mount component that needs to live inside a cabinet with proper ventilation. At 40 °C ambient, total power loss is 106.2 W (80 W coil + 26.2 W iron core), so plan for that heat rejection. Thermal class B (130 °C rise) per IEC 60085 gives the insulation system margin. Dimensions are 0.219 m wide × 0.179 m high × 0.143 m deep. Main circuit connections are flat-type terminals — expect busbar or crimp lug terminations, not screw-clamp wire ends.","metaTitle":"Siemens 4EP4000-3DS00 Commutating Choke, 400V 80A 3-Phase","metaDescription":"Siemens 4EP4000-3DS00 3-phase commutating choke for converters.
