FU) designed for variable-frequency drive input line conditioning. It handles a maximum AC current of 11.2 A at 480 V, with a rated operational current of 10.08 A, and provides 1.3 mH inductance per phase. Rated for 50/60 Hz operation at 40°C ambient, this choke dissipates 23 W in the coil and 11 W in the iron core, with Class B insulation (130°C rise) per IEC 60085. Connection is via screw-type or tab terminals on the main circuit. ## Panel integration At 0.124 m wide, 0.122 m tall, and 0.073 m deep, this choke fits a standard backpanel footprint. The IP00 rating requires enclosure mounting — plan for a gland plate or terminal box to maintain the panel's overall IP rating. Screw/tab terminals accept ring or fork lugs; torque to the manufacturer's specification for the connection type used.","metaTitle":"Siemens 4EP3400-1US00 Mains Choke for VFD, 11.2A, 480V","metaDescription":"Siemens 4EP3400-1US00 mains choke for VFD, 3-phase, 11.2A max, 480V AC, 1.3 mH, IP00, EN 61558-2-20, UL/CSA recognized.
