Above that, derating applies: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. In a crowded panel with elevated internal temperatures, size the load circuit to the derated value at the expected ambient — not the 80 A nameplate. ## Auxiliary and Trip Configurations There is no undervoltage release, no ground fault monitoring, no phase failure detection, and no communication function — it is a straightforward line-protection breaker without add-on electronics. A voltage trigger is present for remote signaling. The 3VA1180-4EF32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole footprint matches standard SENTRON 3VA mounting rails; verify the panel cutout and busbar spacing against the 76.2 mm width before committing the BOM.","metaTitle":"Siemens 3VA1180-4EF32-0JH0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1180-4EF32-0JH0 molded case circuit breaker, 80 A rated current, 3-pole, 121 kA breaking capacity at 240 V.
