Its job is to limit current rise during commutation, reduce harmonic distortion, and protect the converter's input diodes or thyristors from excessive di/dt. Rated for 405 A continuous (450 A maximum) at 830 V AC, 50 Hz, with an inductance of 68 µH and a relative inductive voltage drop of 2% at rated current. That 2% drop is typical for a line reactor sized to smooth commutation without dragging down the bus voltage noticeably. The 405 A rating at 830 V AC means this choke can sit on the line side of a converter feeding a motor drive pulling that current. The 450 A maximum gives a 10% headroom for short-term overloads — enough for most drive acceleration profiles without saturating the core. Thermal class H (180 °C insulation system) means the choke can run hot — it's built for enclosed converter cabinets where ambient temperatures hit 40 °C and the choke itself sees significant self-heating from the ripple current. Panel builders need to plan for bolted connections rated for the full 405 A. This class of component — a commutating choke — goes between the AC mains and a variable-frequency drive, a DC drive converter, or a regenerative supply unit. It smooths the current waveform, limits inrush, and protects the converter's power semiconductors from the switching transients that come from the line itself. Common deployment: on the input of a 400–690 V class drive cabinet feeding a conveyor, pump, or fan motor in the 200–350 kW range. The 830 V rating covers 690 V nominal systems with margin for line swells.","metaTitle":"Siemens 4EU3022-0KA00-1BA0 Commutating Choke, 405A, 830V AC","metaDescription":"Siemens 4EU3022-0KA00-1BA0 commutating choke for converter, 3-phase, 405A rated, 830V AC, 68 µH, IP00, thermal class H.
