That means at a 480 V panel feed (common in North American industrial), the available fault current must be below the 415 V rating — 52.5 kA — to stay within the breaker's interrupting capability. Rated insulation voltage is 800 V, so the breaker is suitable for 480/277 V and 600/347 V systems with margin. Above that, derating applies: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If the panel ambient runs at 60 °C, the breaker's effective ampacity is 77 A — not 80. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm) is the critical dimension for DIN-rail or mounting-plate spacing — verify the busbar stack and adjacent breaker clearances.","metaTitle":"Siemens 3VA1180-3EE42-0AA0 SENTRON MCCB, 80 A, 4-Pole, TM220","metaDescription":"Siemens SENTRON 3VA1180-3EE42-0AA0 molded case circuit breaker, 80 A continuous, 4-pole, TM220 release.
