The 3VA1340-5EE32-0AA0-ZD00: The TM220 trip unit gives thermal-magnetic protection: overload (Ir) adjustable from 280 A to 400 A via a dial on the front, and a fixed magnetic short-circuit pickup (Ii) of 10 x In, so 4000 A. That's a steep magnetic setting — typical for motor or transformer feeders where you need to ride through inrush without nuisance tripping.
