The short-circuit breaking capacities are rated across four voltage levels: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
Thermal rating and derating
Above that, derating is gradual: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. If your panel ambient sits at 55 °C or higher, you lose roughly 1.6 A per 5 °C step — factor that into the load calculation rather than oversizing the frame.
Protection class IP40 on the front means it is splash-proof from the operator side but not sealed against dust ingress through the enclosure; mount it in a panel with at least IP54 overall if the environment is dusty.
