Breaking capacity is 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at 500 V — these figures govern fault-interruption capability at the point of installation; the 415 V rating is the one most often checked for European 400 V distribution panels. Front protection is IP40.
Thermal Derating and Power Loss
The 16 A rating holds from 40 °C through 55 °C ambient; at 60 °C and 65 °C it derates to 15 A, and at 70 °C it remains at 15 A. No derating needed below 55 °C for most panel interiors.
