Interrupting capacity varies sharply with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That 52.5 kA at 415 V is the figure most relevant for a 400 V three-phase panel — it gives solid headroom above typical 25–36 kA service-entrance requirements, so selectivity with downstream 10 kA MCBs is straightforward to coordinate. At 690 V the 10.5 kA rating still covers most industrial motor-control-center fault levels.
Above that it steps down: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C.
