The breaker holds its full 80 A rating from 40 °C up through 50 °C, then derates gradually to 74 A at 70 °C, which matters when it's packed into a warm enclosure alongside other heat sources. ## Interrupting capacity and thermal performance The interrupting capacity drops with system voltage — from 75.6 kA at 240 V down to 11.9 kA at 500 V and 690 V. That 11.9 kA floor at 690 V still covers most motor branch circuits on 690 V distribution. The 101.6 mm width (4 inches) occupies two standard 50 mm DIN-rail module spaces, so it fits a 4-pole MCCB footprint common across the SENTRON 3VA family. Rated insulation voltage is 800 V, storage range from -40 °C to 80 °C, operating range from -25 °C to 70 °C.","metaTitle":"Siemens SENTRON 3VA1180-3GE46-0AA0 MCCB, 80 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1180-3GE46-0AA0 4-pole MCCB, 80 A continuous, 75.6 kA at 240 V.
