That matters when the breaker lives in a crowded enclosure — if ambient inside the panel hits 60 °C, you lose 13 A of headroom. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm (HP type), which gives a separate signal for fault vs. manual open.","metaTitle":"Siemens 3VA1225-6EF32-0AG0 SENTRON MCCB, 250A, 220kA","metaDescription":"Siemens 3VA1225-6EF32-0AG0 SENTRON MCCB, 250A rated at 40°C, 220kA at 240V.
