At 240 V AC it handles 121 kA — a very high figure that covers most industrial service-entrance and large subfeed applications. At 415 V AC it's still substantial at 75.6 kA. At 440 V AC it drops to 52.5 kA, and at 500 V or 690 V AC it's 11.9 kA. ## Thermal derating — don't assume 100 A at every ambient At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A.

The difference is in the release and accessories: this one has a TM220 thermal-magnetic release; the 5EF36 variant carries a different release type. If the panel was wired for the same lug positions and bus spacing, it will physically install without rewiring the main conductors.
