Those are the numbers that decide whether this breaker holds on a high-fault transformer secondary or needs an upstream current-limiting device. The thermal derating curve is published: full 250 A up to 50 °C ambient, then 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Dimensions are 158 mm height, 140 mm width, 70 mm depth. The 140 mm width is standard for a 4-pole MCCB in the SENTRON 3VA frame — it occupies the same panel footprint as other 4-pole 3VA breakers in the 250 A class.","metaTitle":"Siemens 3VA1225-4GE42-0AA0 SENTRON MCCB, 250 A, 4-Pole, TM22","metaDescription":"Siemens SENTRON 3VA1225-4GE42-0AA0 molded case circuit breaker, 250 A, 4-pole, TM220 trip unit.
