The 0.043 mH inductance limits the rate of current rise during converter commutation, reducing harmonic distortion and protecting the DC-link capacitors and IGBTs from di/dt stress. ## Current handling and thermal class Three current ratings define the envelope: 630 A maximum continuous (the thermal limit for sizing conductors and fusing), 567 A rated (the design operating point for the 4 % voltage drop), and a peak current of 788 A — the short-duration surge the choke must pass without saturating. At DC the rated value is 772 A, so it also handles DC-link ripple current in six-pulse rectifier circuits. Thermal class H per IEC 60085 means the insulation system withstands 180 °C hot-spot temperature — necessary when the choke sits near a converter's heat sink. The coil dissipates 280 W, the iron core 190 W, for a total 470 W of heat that must be removed from the enclosure. Ambient temperature rating is 40 °C; derate above that.","metaTitle":"Siemens 4EU3622-8CA00-1BA0 Commutating Choke, 630A, 500V AC","metaDescription":"Siemens 4EU3622-8CA00-1BA0 commutating choke for converter drives.
