Its breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that put it in the high-interrupting class for industrial distribution panels.
Above that, it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, 36 A at 70 °C.
Panel fit — dimensions and mounting
Width 76.2 mm, height 130 mm, depth 70 mm. The IP40 front rating means the breaker face is protected against solid objects >1 mm, but the body expects enclosure protection for the terminals.
