The Siemens 4EU2722-0DA00-1BA0 is a 3-phase commutating choke for converter applications, rated at 180 A continuous with a peak current capacity of 250 A. It handles AC voltages up to 690 V and provides an inductance of 0.19 mH, with a relative inductive voltage drop of 4% at rated current. The choke is designed for line-side or load-side use in variable-speed drive systems, limiting current rise during commutation and reducing harmonic distortion on the supply.
Key ratings and their meaning
Rated 180 A continuous, 200 A maximum. 250 A peak handles short-duration overloads. 4% voltage drop at rated current. Thermal class H (180 °C) insulation. Coil loss 190 W, iron core loss 90 W. IP00 means no enclosure — the choke is a bare magnetic assembly with flat-type terminals. The flat connectors accept busbar or cable lugs; plan for proper creepage and clearance distances per IEC 61558-2-20, which is the standard cited in the full description.
Panel-mount component. Width 0.27 m, height 0.248 m, depth 0.187 m. Flat-type terminals for main circuit. Designed for a 3-phase AC supply at 50 Hz or below (0 to 50 Hz operating frequency), it is a line-frequency choke, not a high-frequency output filter. Use it on the line side of a 6-pulse or 12-pulse rectifier, or on the DC link if the circuit is configured for that.
