The 80 A rating holds at 45 °C and 50 °C ambient, then steps down to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 19.2 W, which matters for enclosure heat rise in a sealed panel. The breaker measures 101.6 mm wide by 130 mm high by 70 mm deep. Front-face protection is IP40 — suitable for a clean panel interior but not washdown. The 4-pole design with 100% N-conductor protection means the neutral pole is fully rated and switches with the phases, which is required for some IT or corner-grounded systems.","metaTitle":"Siemens SENTRON 3VA1180-4GE46-0AA0 MCCB, 80A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1180-4GE46-0AA0 molded case circuit breaker, 80A, 4-pole, TM220 release, 121kA interrupting at 240V.
