The Siemens 3VA1180-4ED26-0AA0 is a 2-pole SENTRON molded case circuit breaker (MCCB) rated 80 A at 40–50 °C, with a TM210 thermal-magnetic release for line protection. Its interrupting capacity reaches 121 kA at 240 V AC and 75.6 kA at 415 V AC — numbers that tell you it can clear high-fault currents without upstream coordination issues in most distribution panels.
At 415 V AC the 75.6 kA breaking capacity covers the majority of industrial service-entrance and sub-distribution applications. The thermal derating curve is published: 80 A flat through 50 °C, then 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That means you can run it at full rating in a 50 °C enclosure; above that, you must reduce the load or improve ventilation.
