Above 55 °C, the continuous current must be derated: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. For panel builders, this means the breaker can be installed in a warm enclosure without losing capacity, as long as the derating curve is applied. ## Physical Dimensions and Panel Integration The unit does not include auxiliary contacts or a trip indicator, and no communication function is built in. For applications requiring remote status, an auxiliary trip accessory (order code 3VA9608-0BB11) is available as a separate component.","metaTitle":"Siemens 3VA1225-6EF32-0BA0 SENTRON MCCB, 250 A, 3-pole, Line","metaDescription":"Siemens 3VA1225-6EF32-0BA0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole, line protection, TM240 release, UVR included.
