The IP00 open-frame construction means it mounts inside a cabinet — no touch protection on the choke itself, so panel builders need to account for clearance and guarding. The 4.5 A rated operational current and 5 A thermal max size this choke for a 3-phase VFD input up to about 2.2 kW at 400 V — common for small conveyors, pumps, or fan drives. The 3.7 mH inductance and 2% voltage drop are typical for a 4% impedance reactor, which is the standard choice for reducing harmonic distortion and limiting inrush on the DC bus. At 50 Hz, the core losses are 5.6 W, coil losses 11.5 W — total 17.1 W heat to vent inside the panel. Thermal class B means the insulation system withstands 130 °C hot-spot temperature — fine for a 40 °C ambient with natural convection in a ventilated enclosure. The screw-type and tab terminals accept ring lugs or fork terminals; tab connections suit a quick-disconnect for panel wiring.","metaTitle":"Siemens 4EP3200-2US00 Mains Choke, 3-Phase 500V 5A 3.7mH","metaDescription":"Siemens 4EP3200-2US00 mains choke for VFD. 3-phase, 500V AC, 5A max, 3.7 mH, IP00, UL/CSA recognized.
