At 240 V it interrupts 121 kA; at 415 V it still holds 75.6 kA, dropping to 52.5 kA at 440 V and 11.9 kA at both 500 V and 690 V. For a 100 A frame, those are high-interrupting ratings — it is sized for installations with high available fault current, not a low-fault residential panel. No separate undervoltage module to buy and mount.
At 55 °C it steps down to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. For a panel that runs hot, the 70 °C figure (91 A) is the one to use for sizing. The 70 mm depth fits a standard panel with room for wiring gutters. Maximum power loss is 27.5 W. That is the heat the breaker dumps into the enclosure at full rated current — relevant for thermal calculations in a sealed or high-density panel.
