It smooths line current, limits harmonic distortion, and reduces voltage notching on the supply side — a standard fitment ahead of a drive's rectifier stage. Rated for 9.1 A at 400/480 V AC, 50-60 Hz, with a 1.6 mH inductance and a 2% relative inductive voltage drop at rated current. The 9.1 A maximum current and 8.19 A operational current define the continuous load this choke can carry without saturating. The 2% voltage drop is typical for a line reactor — it tells you the impedance at rated conditions, which governs how much harmonic attenuation you get. The 1.6 mH inductance is the core parameter for sizing against drive input capacitance; too low and the choke won't filter, too high and you risk voltage drop under load. Total power loss is 35 W (25 W coil + 10 W iron core,), which drives the heat load inside the enclosure. Thermal class B means the insulation system is rated for 130 °C hot-spot — standard for industrial chokes. This choke mounts inside a control cabinet, typically on a mounting plate or DIN rail via an optional bracket. The screw-type and tab terminals accept ring lugs or fork terminals for the main power circuit — no special tooling needed. Dimensions are 0.124 m wide by 0.122 m high by 0.073 m deep, so it fits a standard 200 mm deep enclosure with room for wiring clearance.","metaTitle":"Siemens 4EP3400-2US00 Mains Choke, 9.1 A, 1.6 mH, 400/480 V","metaDescription":"Siemens 4EP3400-2US00 mains choke for variable-frequency drives. 3-phase, 9.1 A, 1.6 mH, 400/480 V AC, 50-60 Hz, IP00.
