The 800 A rating holds through 50 °C ambient. Above that, it derates linearly: 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C. For a panel OEM packing breakers into a confined enclosure, that derating curve determines whether the 800 A frame is still the right choice or whether you step up to the next frame size. ## Integrated auxiliary and release options ## Physical footprint Dimensions are 320 mm high, 210 mm wide, and 120 mm deep. The 210 mm width fits standard MCCB panel cutouts for a 3-pole frame at this rating. Verify the gland-plate opening and bus-bar spacing before committing the panel layout.","metaTitle":"Siemens 3VA1580-5EF32-0CH0 SENTRON MCCB, 800A, 187kA at 240V","metaDescription":"Siemens 3VA1580-5EF32-0CH0 SENTRON molded case circuit breaker, 800A rated at 40°C, 187kA breaking at 240V. 3-pole, line protection, undervoltage release.
