That's the kind of interrupting rating that keeps selectivity intact downstream without cascading upstream breakers. ## Thermal derating and ambient reality At 55 °C it drops to 76.8 A, at 60 °C to 75.2 A, and at 65 °C to 73.6 A, bottoming at 72 A at 70 °C. That's a shallow curve; you lose only 10 % at the top of the operating range. If your panel sits near a kiln or a hot process line, you can still load it close to nameplate without oversizing. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a compact 3-pole footprint that fits standard MCCB panel cutouts.","metaTitle":"Siemens 3VA1080-4ED32-0AH0 MCCB, 80 A, 3-Pole, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1080-4ED32-0AH0 molded case circuit breaker, 80 A rated, 3-pole, 121 kA breaking at 240 V.
