Rated for 400/480 V AC at 50/60 Hz, it carries a maximum continuous current of 16 A and a rated operational current of 14.4 A. The 16 A maximum AC current (Ithmax) sets the thermal limit for continuous duty at 40 °C ambient. The 14.4 A rated operational current (I LN) is the figure to match against your drive's input current at full load — not the motor FLA. If your drive draws 14 A or less at rated output, this choke is sized correctly. The 2 % voltage drop (Uk) is a standard value for line reactors; it provides effective harmonic mitigation without excessive voltage sag that could starve the drive DC bus. The 31 W coil loss plus 10 W iron loss (41 W total) must be considered in enclosure thermal calculations, especially in a sealed cabinet. This is an open-frame (IP00) component — no enclosure, no finger-safe terminals. Dimensions are 0.148 m wide, 0.139 m high, and 0.068 m deep. Connections are via screw-type terminals, which accept standard power wiring. The thermal class B insulation (130 °C rise) means it can run at full rated current in a 40 °C ambient without exceeding the winding temperature limit. In a typical panel, allow at least 50 mm clearance around the choke for airflow; forced ventilation may be needed if other heat sources are nearby. ## Compliance documentation The product is designed to EN 61558-2-20 (safety of transformers, reactors, and power supply units) and is UL/CSA recognized as noted in the description. RoHS and REACH compliance is standard for Siemens industrial components in this series, though the specific declarations should be requested with the order if required for your quality documentation.","metaTitle":"Siemens 4EP3500-0US00 Mains Choke, 3-Phase 480V 16A, 0.88 mH","metaDescription":"Siemens 4EP3500-0US00 mains choke for VFDs, 3-phase AC, 480V, 16A max, 0.88 mH, 2% voltage drop, IP00, screw terminals.
