The Siemens 4EU3022-1BA00-0AA0 is a 3-phase commutating choke designed for converter applications, rated at 400 V AC operating voltage and 50 Hz. It handles a maximum AC current of 355 A and a DC rated current of 435 A, with a peak current capability of 444 A. The choke provides an inductance of 0.000062 H and a relative inductive voltage drop of 4% at rated current, voltage, and frequency. This is a panel-mount component with IP00 protection — no enclosure, so it must be installed inside a suitable cabinet or cubicle that provides the required ingress protection for the environment.
Ratings and thermal class
The choke is rated for a 40 °C ambient temperature and carries thermal class H per IEC 60085, meaning the insulation system can withstand a continuous hot-spot temperature of 180 °C. Total power loss breaks down into 220 W in the coil and 102 W in the iron core — 322 W total that must be dissipated by the enclosure ventilation or forced airflow.
Physical dimensions
The choke measures 0.3 m wide, 0.269 m high, and 0.211 m deep. These dimensions matter for panel layout — it is a substantial component, not a DIN-rail device, so plan for dedicated mounting and clearance around the flat terminals for cable bending radius.
