It sits between the supply and the drive, smoothing current draw and limiting harmonic distortion. Rated for 400/480V AC at 50/60Hz, it carries a continuous rated current of 2.7A with a 3A maximum, and provides 0.0097H (9.7mH) of inductance with a 4% relative inductive voltage drop at rated conditions. ## What the ratings mean in practice The 2.7A rated current (3A max) tells you this choke is sized for a drive drawing roughly that continuous input current — think a small pump or fan motor on a 400V line. The 4% voltage drop at rated current is the trade-off: you get meaningful harmonic attenuation and dV/dt protection, but the drive sees a slightly lower bus voltage under load. That 4% figure is measured at the rated current, voltage, and frequency — it's the design point, not a worst-case ceiling. The 0.0097H inductance is fixed; this isn't a tunable reactor. It's wound for thermal class B (130°C rise per IEC 60085), with a 14W copper loss and 6W iron loss at rated load. That's 20W total heat you need to vent — IP00 means no enclosure, so it's open-frame and intended for a cabinet with forced air or natural convection. Mount it with clearance around the core. This choke is panel-mount, not DIN rail. The 0.108m height and 0.088m width footprint fits a standard subpanel, and the 0.057m depth means it won't crowd the gland plate in a 200mm-deep enclosure. Connections are screw-type or tab terminals on the main circuit — solid for a permanent install, but not quick-disconnect. You'll land line-side lugs on one end and drive-side on the other.","metaTitle":"Siemens 4EP3201-0US00 Mains Choke, 3-Phase, 2.7A, 0.0097H","metaDescription":"Siemens 4EP3201-0US00 mains choke for variable frequency drives. 3-phase, 400/480V AC, 2.7A rated current, 9.7mH inductance, 4% voltage drop.
