Current rating holds at 25 A from 40 °C through 50 °C, then steps down to 24 A at 55–60 °C and 23 A at 65–70 °C. The 70 mm depth and 76.2 mm width (3-inch standard) fit a typical MCCB slot on a DIN rail or panel-mount base; the 130 mm height leaves room for auxiliary switch wiring above. Maximum power loss is 8.5 W — negligible for enclosure thermal calculations but worth noting in sealed cabinets.","metaTitle":"Siemens 3VA1125-6EF32-0AD0 SENTRON MCCB, 25A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1125-6EF32-0AD0 molded case circuit breaker, 3-pole, 25A rated at 40°C, 220kA breaking capacity at 240V.
