It carries a breaking capacity of 52.5 kA at 240 V, stepping down to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V — so the interrupting rating you need to match against the available fault current at your system voltage is the one that governs fit. Rated insulation voltage is 800 V, and the unit dissipates a maximum of 19.2 W under load. Operating temperature spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. ## Derating and panel integration At 40 °C, 45 °C, and 50 °C the breaker holds its full 80 A rating. Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If your enclosure runs hot — say a packed panel near a furnace line or a roof-mounted cabinet in direct sun — that 74 A at 70 °C figure is the one you spec against, not the 80 A nameplate. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. The 76.2 mm width (3 inches) is a standard MCCB footprint for 3-pole units.","metaTitle":"Siemens 3VA1080-2ED36-0JH0 SENTRON MCCB, 80 A, 3-pole","metaDescription":"Siemens SENTRON 3VA1080-2ED36-0JH0 molded case circuit breaker, 80 A, 3-pole, 52.5 kA at 240 V.
