Above that it derates: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Footprint is 140 mm wide, 158 mm tall, 70 mm deep. That 140 mm width for a 4-pole 250 A frame is standard for SENTRON 3VA — it fits the same DIN-rail or mounting-plate cutout as other 3VA breakers in this frame class. The shunt trip adds a couple of terminals on the left side; plan for wire bending space around it.","metaTitle":"Siemens 3VA1225-6GF42-0JH0 SENTRON MCCB, 250 A, 4-Pole, 220","metaDescription":"Siemens 3VA1225-6GF42-0JH0 SENTRON molded case circuit breaker, 250 A, 4-pole, 220 kA interrupting at 240 V.
