The 500 V rated insulation voltage (Ui) confirms it is rated for 480Y/277 V systems common in North American panels. At 55 °C it derates to 49 A, at 60 °C to 48 A, at 65 °C to 46 A, and at 70 °C to 45 A. For a panel that runs warm — say 55 °C inside the enclosure — the breaker still carries 49 A continuous without nuisance tripping. The maximum power loss is 9.74 W, which is modest for a 50 A frame and keeps internal cabinet heating manageable. Depth is 70 mm (2.76 in), height 130 mm (5.12 in). Front IP40 protection means it is sealed against tools and fingers but not washdown; install inside a rated enclosure for wet or dusty environments.","metaTitle":"Siemens 3VA1150-3ED26-0AA0 SENTRON MCCB, 50A, 2-Pole, 75.6kA","metaDescription":"Siemens 3VA1150-3ED26-0AA0 SENTRON molded case circuit breaker, 50A at 40°C, 2-pole, 75.6 kA interrupting at 240 V.
