It carries a continuous current rating of 80 A at 40 °C, holding that full rating through 50 °C before it begins to derate — at 55 °C it's still good for 78 A, at 65 °C it's 75 A, and at 70 °C it's 74 A. That thermal curve means you can run it in a warm enclosure without losing much headroom. The interrupting capacity tells you where it clears faults safely: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. Those numbers cover most commercial and light-industrial panelboard applications. It's a straight line-protection breaker for standard feeder or branch circuits.
Panel fit and environment
The 3VA1080-2ED36-0AA0 is a 3-pole breaker with a width of 76.2 mm (3 in), depth of 70 mm (2.76 in), and height of 130 mm (5.12 in). Protection class on the front is IP40, so it's fine for dry indoor enclosures; not rated for washdown.
