Siemens SENTRON 3VA1080-2ED36-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated 80 A at 40 °C, with a maximum breaking capacity of 52.5 kA at 240 V.
Breaking capacity drops from 52.5 kA at 240 V to 32 kA at 415 V, then to 13.6 kA at 440 V, and further to 7.5 kA at both 500 V and 690 V. The thermal rating holds at 80 A up to 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That derating curve is what you use for panel ambient — don't size by the 40 °C number alone if your enclosure runs hot.
Panel integration and fit
Dimensions are 70 mm depth, 76.2 mm width (standard 3-pole MCCB footprint), and 130 mm height. Communication function is absent — this is a standalone thermal-magnetic breaker, not a networked unit.
