That 100 A holds steady all the way up to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — so in a hot panel you still have most of the capacity. The breaking capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.
The overcurrent release is an ETU310M electronic trip unit, which gives you adjustable thermal-magnetic curves for motor or feeder protection.
