It smooths current harmonics and limits inrush, protecting both the drive and the upstream supply. Rated for 3-phase AC at 400 V, it carries a continuous rated current of 3.6 A with a maximum of 4 A, and provides 11 mH of inductance per phase. The 3.6 A rated current (4 A max) sizes this choke for small drives — think fractional-horsepower pumps, fans, or conveyors on a 400 V line. The 11 mH inductance value is what actually filters the harmonics; matching this to the drive's DC-link inductance and switching frequency is the selection gate. The screw-type and tab terminals accept standard ring lugs or fork terminals. Dimensions of 0.148 m wide by 0.139 m tall by 0.068 m deep fit on a mounting plate or DIN-rail bracket. Thermal class B insulation assumes free convection at a 40 °C ambient. Designed to EN 61558-2-20 (safety of transformers, reactors, and power supply units). Thermal class B per IEC 60085. The IP00 protection class means it is a panel-mount component, not a standalone unit. No UL or CSA listing is stated in the available data; verify with your local Siemens representative if a specific agency mark is required for your jurisdiction.","metaTitle":"Siemens 4EP3500-0EK00 Mains Choke, 3.6A, 400V, 3-Phase","metaDescription":"Siemens 4EP3500-0EK00 mains choke for frequency converters. 3-phase, 400V AC, 3.6A rated, 11 mH, IP00.
