Breaking capacity — the number that decides if it clears the fault
Breaking capacity drops as voltage rises: 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V.
The 200 A rating holds up to 50 °C ambient. At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. Mounting on a standard DIN rail (105 mm width, 158 mm height, 70 mm depth) fits a typical 600 mm wide panel section.
