FU, 3-phase AC mains choke, 35.5A max, 480V, 0.4mH, 2% voltage drop, IP00, screw terminals.","salesMarkdown":"The Siemens 4EP3700-2US00 is a three-phase AC mains choke (line reactor) designed for installation ahead of a frequency converter (Netzdrossel f. FU). It limits harmonic distortion and reduces current spikes on the drive input, which protects both the converter and upstream distribution gear. Rated for a maximum continuous current of 35.5 A at 480 V AC, 50/60 Hz, with a rated operational current of 31.95 A. The inductance is 0.0004 H and the relative inductive voltage drop is 2% at rated current, voltage, and frequency. Total power loss splits between the coil (49.6 W) and the iron core (9.7 W), with thermal class B insulation. The 40 °C ambient rating is the standard reference; derate above that. ## Mounting and connection Dimensions are 0.178 m wide, 0.153 m tall, and 0.105 m deep, so it fits a standard backplate footprint with room for screw-terminal access on the main circuit connections. Main circuit connections are screw-type terminals, which accept common lug or ring-terminal wiring. No DIN-rail clip; this is a bolt-down component.","metaTitle":"Siemens 4EP3700-2US00 Mains Choke for Drive, 35.5A 480V","metaDescription":"Siemens 4EP3700-2US00 mains choke for frequency converter, 3-phase, 35.5A max, 480V AC, 0.4mH, IP00, screw terminals, active production.
