Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. Three poles, so it switches all three phases. ## Derating and thermal reality Above that it steps down: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The 76.2 mm width (three-pole) is standard for a 160 A frame SENTRON; it occupies one 3-pole mounting position on the DIN rail or bolted bus. Mechanical endurance is rated at 15,000 cycles. That's the number of on-off operations the mechanism is designed for before wear-out. For a line-protection breaker that sees maybe a few operations a year, that's effectively lifetime. For a breaker used as a disconnect that cycles daily, track it.","metaTitle":"Siemens 3VA1180-4EF36-0AD0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1180-4EF36-0AD0 SENTRON molded case circuit breaker, 80 A rated, 3-pole, 121 kA breaking at 240 V.
