This is the component that sits between the converter and the line to limit di/dt and reduce harmonic distortion — without it, the converter's switching edges can cause nuisance trips upstream or shorten the life of the DC-link capacitors. The lifecycle stage for this order code is listed as mature, meaning it is not in active phase-in or phase-out — it is a stable, established catalog item. For a BOM freeze, this is a low-risk line item; no immediate PCN or LTB is signaled. Mounting dimensions are 0.178 m wide, 0.153 m high, and 0.12 m deep. Thermal class B (IEC 60085) means the insulation system is rated for a maximum hot-spot temperature of 130 °C, with a 40 °C ambient as the reference point. The coil dissipates 59 W and the iron core another 14.1 W — that 73 W total needs to be considered in the panel's thermal budget. Peak current rating is 39 A, and the DC-rated current is 38.6 A — useful if the converter's DC link is being smoothed by this choke in a non-standard topology. The rated continuous current (Ith) is 28.35 A, which is the figure to use for continuous duty under IEC 61558-2-20. If your load profile is intermittent or the ambient is below 40 °C, you may get some headroom, but the 28.35 A is the safe design number for a 50 Hz line.","metaTitle":"Siemens 4EP3801-8DS00 Commutating Choke, 31.5A, 500V","metaDescription":"Siemens 4EP3801-8DS00 commutating choke for converters, 3-phase, 31.5A max, 500V AC, 50Hz, 0.92mH, IP00, screw terminals.
