An integrated undervoltage release (UVR) is factory-fitted — part number 3VA9608-0BB11 for the auxiliary trip assembly. That means if the control voltage drops, the breaker trips automatically, which is useful for safety interlocks or emergency-stop circuits that need to kill power when the control supply fails. ## Ratings that matter for panel fit The IP40 front protection means it's splash-proof from the front but not sealed — fine for indoor panels, not for washdown zones. Current rating holds at 80 A from 40 °C up to 50 °C, then derates to 76.8 A at 55 °C and 72 A at 70 °C. That thermal curve matters when you pack breakers tight in a panel — if ambient runs hot, you lose about 10% of the rating by 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for this class. No auxiliary contacts are fitted, so if you need remote status feedback, you'll add those separately.","metaTitle":"Siemens 3VA1080-2ED36-0BA0 SENTRON MCCB, 80A, 52.5kA at 240V","metaDescription":"Siemens SENTRON 3VA1080-2ED36-0BA0 molded case circuit breaker, 80A rated current, 52.5kA breaking capacity at 240V AC.
