Thermal derating is mild: it holds 25 A from 40 °C to 50 °C, then drops to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. That means in a warm panel — say 55 °C — you still get 24 A continuous without nuisance tripping. Front IP40 protects against tool drops during commissioning. Trip indicator is present — visible flag on the front for quick fault isolation.","metaTitle":"Siemens 3VA1125-6EF32-0AH0 SENTRON MCCB, 25A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1125-6EF32-0AH0 molded case circuit breaker, 25A rated continuous current, 220 kA breaking capacity at 240 V.
