Rated insulation voltage is 800 V (Ui), and the interrupting ratings climb to 220 kA at 240 V AC, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so it handles high available fault current on the line side of a motor starter without needing a current-limiting fuse upstream.
Above that it derates: 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. The IP40 front protection is typical for panel-mounted MCCBs — it keeps tools and fingers out but isn't rated for washdown environments.
