It handles 500V AC at 50/60 Hz, with a maximum AC current of 290A and a rated operational current of 261A. The 0.048 mH inductance and 1.5% relative inductive voltage drop are sized to limit di/dt and smooth commutation notches in the DC link of a line-commutated converter — the kind you find in variable-speed drives or DC crane controls. The 290A AC maximum current and 261A AC rated operational current define the continuous thermal capacity at 40°C ambient. The 355.3A DC rated current tells you the DC-link side can carry that much continuous current — useful if you are paralleling converter modules. Thermal class H means the insulation system withstands 180°C hot-spot temperature, so the choke can live in a warm cabinet without derating prematurely. IP00 means no enclosure — this is a panel-mount component that needs a cabinet or cubicle to keep fingers and debris off the flat-type terminals. The 176W coil loss plus 78.2W iron-core loss sum to about 254W of heat that must be vented out of the enclosure. This choke mounts in the AC line or DC link of a 3-phase converter — think regenerative drives, elevator drives, or any six-pulse rectifier front end where commutation notches need smoothing. The flat-type terminals accept busbar or crimp lugs; no DIN-rail clip here, so plan for bolt-down panel mounting. At 0.27m wide × 0.248m tall × 0.187m deep, it fits a standard 600mm-wide cabinet bay with room for cabling on both sides. The lifecycle stage is marked mature, meaning Siemens has no active phase-out plan, but this is not a high-turnover catalog item either. It is not the same class as the 5SJ3140-7 or 5SQ2270-2YA04 miniature breakers — those are SENTRON panel protectors with different form factor and function. No direct drop-in replacement exists; this choke is specified by its inductance, current, and voltage class, not by a breaker frame.","metaTitle":"Siemens 4EU2722-0EQ00-1BA0 Commutating Choke, 290A AC, 500V,","metaDescription":"Siemens 4EU2722-0EQ00-1BA0 commutating choke for converter duty. 3-phase, 500V AC, 290A AC max, 261A rated.
