The Siemens 4EU2522-4BA00-0AA0 is a 3-phase commutating choke designed for converter drives — it sits between the drive and the line to limit current rise rates and reduce harmonics on the DC link. Rated 400 V AC at 50 Hz, it handles 180 A maximum AC current (162 A operational AC rated current) and 220.5 A DC rated current, with an inductance of 0.12 mH and a 4% inductive voltage drop at rated conditions.
Dimensions are 0.225 m wide, 0.21 m high, 0.16 m deep. Terminals are flat-type connectors. Ambient temperature rating is 40°C.
No direct second-source exists from the evidence — the 5SJ3140-7 and 5SQ series are miniature circuit breakers, not chokes. This part is specific to Siemens converter applications; if you're replacing a choke in an existing drive cabinet, verify the mounting footprint and inductance value match your circuit.
