Breaking capacity is the headline figure here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 7.5 kA at 500 V and 690 V.
Rated current holds flat at 80 A from 40 °C through 50 °C, then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That means in a sealed panel running at 55 °C, you still get 78 A continuous — no need to oversize the frame for a warm enclosure. Front IP40 protects against tool entry during commissioning. Rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C. Maximum power loss is 19.2 W — relevant for thermal budgeting inside a multi-breaker panel.
