Rated 80 A continuous at 40 °C, the 3VA1180-3EF32-0JH0 holds that figure through 50 °C before starting to derate — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That's a shallow derating curve, so in a warm panel the breaker still delivers near its nameplate. Maximum power loss is 19.2 W. Width 76.2 mm, height 130 mm, depth 70 mm — standard 3-pole MCCB footprint for a 3VA frame.","metaTitle":"Siemens 3VA1180-3EF32-0JH0 SENTRON MCCB, 80A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0JH0 molded case circuit breaker, 80A rated at 40°C, 3-pole, 75.6kA interrupting at 240V.
