Rated 80 A continuous at 40 °C across all three poles, it holds that rating through 50 °C before a gentle derating curve begins — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. The interrupting capacity tells you where it can sit in the fault hierarchy: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Maximum power dissipation is 19.2 W — plan for that heat in a sealed enclosure. The shunt trip (STL) is the only auxiliary release fitted — if you need UVR or a separate alarm contact, that's a different order code in the 3VA family.
