At 415 V it still interrupts 154 kA, and at 690 V it holds 17 kA, so the part suits both 400 V and 690 V industrial supplies. The 80 A rating holds flat from 40 °C to 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If your panel ambient hits 55 °C, you lose 2 A — not a showstopper for most motor feeders, but worth checking against the continuous load. Maximum power loss is 19.2 W, which factors into the enclosure thermal budget; a standard steel enclosure with natural convection handles that, but a sealed stainless box may need a vent or fan. The storage limit governs handling, not running — fine for unheated warehouses in cold climates. ## Active lifecycle — no PCN watch needed for this BOM line Lifecycle status is current — no phase-out or last-time-buy horizon on record. For an OEM building this into a panel design, that means no requalification trigger from the breaker side in the near term.","metaTitle":"Siemens 3VA1180-6EF32-0AA0 SENTRON MCCB, 80 A, 220 kA at 240","metaDescription":"Siemens 3VA1180-6EF32-0AA0 SENTRON 3-pole molded case circuit breaker, 80 A rated at 40 °C, 220 kA breaking capacity at 240 V.
