Breaking capacity drops as voltage rises: 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 11.9 kA floor at 690 V is the number to check if your panel runs a 690 V line — it's still adequate for most motor branch circuits but not for high-fault mains at that voltage.
The 80 A rating holds steady from 40 °C to 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
