At 240 V the breaker interrupts 121 kA; at 415 V it holds 75.6 kA; at 440 V it drops to 52.5 kA; at 690 V it still clears 11.9 kA. That curve tells you the 3VA1180-4EF32-0AB0 is built for high-fault 480Y/277 V panels where the available short-circuit current sits well above 50 kA. At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. The 70 mm depth and 76.2 mm width fit the standard 3VA mounting footprint; the 130 mm height is the same as the rest of the 3VA frame. ## What it does not carry If the application requires remote tripping, ground-fault protection, or adjustable trip curves, this is not the variant; you step up to the 3VA1 with an electronic ETU release.","metaTitle":"Siemens 3VA1180-4EF32-0AB0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1180-4EF32-0AB0 SENTRON molded case circuit breaker, 80 A rated, 3-pole, TM240 release.
