The interrupting ratings are 187 kA at 240 V and 121 kA at 415/440 V; at 690 V it still clears 7.5 kA.
Above that it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. The case dimensions are 248 mm high × 138 mm wide × 110 mm deep, which is the standard 3VA frame footprint; it will bolt into the same mounting pattern as other 3VA breakers in this frame size.
