The Siemens 4EP3200-4US00 is a three-phase mains choke (line reactor) designed for variable-frequency drive input circuits. It carries a rated operating voltage of 400/480 V AC at 50/60 Hz and a maximum continuous current of 1.5 A, with a rated current of 1.35 A. This is an open-frame (IP00) component, so it must be mounted inside an enclosure that provides physical protection and clearance for airflow. The total power loss splits into 16.7 W in the coil and 4.5 W in the iron core at rated load and 40 °C ambient — factor that into your enclosure thermal budget. Thermal class B per IEC 60085 means the insulation system is rated for a 130 °C hot-spot temperature, which is standard for this class of reactor and leaves headroom for moderate overloads.
The 4EP3200-4US00 measures 0.088 m wide by 0.108 m tall by 0.057 m deep. It is not a DIN-rail snap-on device — the screw-type and tab terminals indicate it is intended for panel-mount or chassis-mount with wiring lugs. Plan for a dedicated mounting plate and leave clearance around the IP00 core for convection cooling.
