Rated 40.5 A continuous with a 45 A maximum, it handles 400 V AC at 50 Hz. The 45 A maximum (I thmax) is the short-term overload ceiling; sustained operation at 45 A requires derating. The 0.62 mH inductance at 4 % voltage drop (u k) is the standard impedance for 400 V class drives — it limits DC bus ripple and reduces harmonic distortion to within typical grid-code limits. Mounts on the panel floor or a mounting plate — no DIN rail, this is a bolted-down component. The 0.178 m width, 0.153 m height, and 0.12 m depth footprint fits a typical drive cabinet section alongside the input contactor and fuse block. Thermal class B (130 °C) insulation per IEC 60085 means it can run hot without degrading the winding; the 52.8 W coil loss and 19.5 W iron-core loss total about 72 W of heat to vent in the enclosure. Mature lifecycle stage — established, stable design still in the Siemens portfolio. No EOL notice or successor code appears.","metaTitle":"Siemens 4EP3801-3DS00 Commutating Choke, 45A 400V 50Hz 0.62m","metaDescription":"Siemens 4EP3801-3DS00 commutating choke for converters, 3-phase, 45A max / 40.5A rated, 400V AC, 50Hz, 0.62mH, IP00, screw terminals.
