Power loss runs 19.2 W max, which matters for thermal coordination inside a sealed enclosure. ## Thermal derating and ambient range At 55 °C it derates to 78 A, at 60 °C to 77 A, at 65 °C to 75 A, and at 70 °C to 74 A. For a panel that sees 55 °C internal air, the continuous load must stay under 78 A — the spec table gives the exact curve, no guessing.","metaTitle":"Siemens 3VA1180-5EF36-0KH0 SENTRON MCCB, 80A, 187kA at 240V","metaDescription":"Siemens 3VA1180-5EF36-0KH0 SENTRON molded case circuit breaker, 80A rated, 187kA interrupting at 240V, 3-pole, line protection, shunt trip, active production.
