Breaking capacity drops as voltage climbs: 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 12 kA at 500 V. That's a lot of fault-clearing muscle for a 320 A frame — you've got selectivity room downstream without worrying about the main tripping on a branch fault.
At 60 °C it derates to 15 A, and it stays at 15 A through 70 °C. That's a shallow derating curve — good sign the thermal element is sized conservatively.
76 kA at 415 V AC. At 240 V it's 121 kA, at 440 V it's 53 kA, and at 500 V it's 12 kA.
