The 0.52 mH inductance at 71 A maximum (63.9 A rated continuous) and 500 V AC operating voltage is sized for medium-power drives in the 30–50 kW range, depending on the drive's DC-link configuration. The 71 A maximum current (Ithmax) at 50 Hz is the thermal limit under worst-case conditions — the choke can handle this continuously without exceeding the Class B (130 °C) insulation system. The 63.9 A rated current (ILN) is the nominal design point for voltage drop calculations. The 4 % relative inductive voltage drop (Uk) at rated current and frequency means the choke will drop about 20 V at 500 V / 63.9 A — a standard value for most drive line reactors. The 87 A DC rating confirms it can also serve in DC-link applications, though the primary role is AC line-side commutation. The flat-type terminals (flat connector) accept busbar or cable lugs; plan for M8 or M10 ring terminals depending on your lug size. Dimensions are 0.219 m wide × 0.179 m high × 0.143 m deep — about the footprint of a small shoe box. Mounting is via the baseplate; no DIN-rail clip is provided. The 80 W coil loss plus 34 W iron core loss (114 W total) must be considered in your panel thermal budget — allow ventilation around the choke or derate ambient if the cabinet is sealed.","metaTitle":"Siemens 4EP4002-2DS00 Commutating Choke, 71A / 63.9A, 0.52 m","metaDescription":"Siemens 4EP4002-2DS00 commutating choke for converter applications. 3-phase, 500V AC, 71A max / 63.9A rated, 0.52 mH, IP00.
