It is a straightforward thermal-magnetic breaker for feeder or branch-circuit protection where remote tripping via the shunt trip is required. The 80 A rating holds from 40 °C through 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. In a sealed panel with ambient above 50 °C, plan for the reduced continuous current. Maximum power loss is 19.2 W — account for this in the panel thermal budget, especially when breakers are ganged without spacing.","metaTitle":"Siemens SENTRON 3VA1080-3ED32-0HC0 MCCB, 80 A, 3-Pole, 70 mm","metaDescription":"Siemens SENTRON 3VA1080-3ED32-0HC0 molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 75.6 kA at 240 V.
