Its primary job is to limit current rise and reduce harmonic distortion on the DC link or AC input of a variable-frequency drive or rectifier. Rated at 400 V AC, 50 Hz, this choke handles a maximum AC current of 250 A and a DC rated current of 306.3 A. The 225 A AC operational current rating is the continuous duty figure. Inductance is 84 µH (0.000084 H). That's a relatively low value, suited for larger drives where the line impedance already provides some filtering. The thermal class H (180 °C) insulation system means the choke can run hot without degrading the winding — important when mounted inside a crowded cabinet with limited airflow. Total power loss splits between the coil (174 W) and the iron core (75 W), summing to about 249 W at rated load.
The flat-type terminals are a Siemens standard for this class of choke. They accept busbar or cable lug connections; verify your existing lug width against the terminal opening before committing the BOM line. No adapter bracket needed for the mounting footprint — it's a panel-mount component with dimensions 0.27 m wide × 0.248 m tall × 0.187 m deep.
Deployment Context
Mount this choke inside a ventilated electrical enclosure — IP00 means no ingress protection, so it needs a clean, dry environment. The 0.27 m width and 0.187 m depth fit a standard 800 mm wide cabinet with room for side cable ducts. Plan for the 249 W heat dissipation: forced ventilation or a larger cabinet volume than the drive alone would require. The flat-type terminals are designed for busbar connection. Use busbars rated for 250 A continuous.
