It delivers 0.25 mH inductance with a 4 % relative inductive voltage drop at rated conditions — sized to limit dI/dt and smooth commutation notches on the line side of a 6-pulse or 12-pulse converter bridge. The 0.136 m depth, 0.225 m width, and 0.21 m height footprint fits into standard cabinet layouts, but the IP00 rating means it needs enclosure-level protection — it is a panel-mount component, not a standalone device. The 100.8 A rated current (112 A max) at 50 Hz is the continuous thermal current the choke can carry at its 40 °C ambient rating. If your converter line current exceeds that, you need a larger choke or derating. The 0.25 mH inductance is the value that governs the commutation notch smoothing — too low and the dI/dt stress on the diodes/IGBTs rises; too high and the voltage drop eats into the DC bus margin. The 4 % relative inductive voltage drop is a design parameter: at rated current and frequency the choke drops about 4 % of the line voltage, which the converter must tolerate. The DC-rated current of 137.2 A reflects the choke's ability to handle the DC-side ripple component in a converter circuit — useful when the same choke is placed in the DC link rather than the AC line. The 120 W coil power loss and 38 W iron-core loss at rated conditions tell you the thermal load the enclosure must dissipate; that 158 W total is not trivial in a sealed cabinet. Class H insulation (IEC 60085) means the winding can withstand 180 °C hot-spot temperature — a safety margin for converter duty where harmonics add extra thermal stress. The flat-type terminal for the main current circuit accepts bus-bar or cable-lug connections typical of power-electronics wiring.","metaTitle":"Siemens 4EU2422-1AA00-0AA0 Commutating Choke, 100.8 A, 400 V","metaDescription":"Siemens 4EU2422-1AA00-0AA0 3-phase commutating choke for converters.
