This is a 2-pole unit, rated insulation voltage 500 V, with an operating voltage of 415 V AC and 250 V DC. Note the thermal derating: at 55 °C it's 78 A, at 65 °C it's 75 A, and at 70 °C it's 74 A — so if the panel ambient runs hot, the effective ampacity drops. Breaking capacity of 75.6 kA at 240 V AC and 52.5 kA at 415 V AC tells you the maximum fault current the breaker can safely interrupt at those voltages. For a 480 V system, you'd need to check the 3VA manual for the DC rating curve — the evidence notes that DC switching values are covered in the device manual, not in the basic spec table. Dimensions are 70 mm deep, 50.8 mm wide (2 inches), 130 mm tall. The 2-inch width per pole is standard for SENTRON 3VA breakers, meaning it occupies two 18 mm DIN-rail spaces. This is a basic thermal-magnetic breaker for line protection. Lifecycle status is current.","metaTitle":"Siemens 3VA1180-3ED26-0AA0 SENTRON MCCB, 80A, 2-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1180-3ED26-0AA0 molded case circuit breaker, 80A rated at 40°C, 2-pole, 75.6kA breaking at 240V.
