Above 55 °C it steps down: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. The interrupting ratings climb fast at lower voltages: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. For a 480 V panel, you're looking at roughly 75 kA SCCR — plenty of headroom for most industrial services. This is a line-protection design (not motor-protection), so it's sized for feeder or main breaker duty. It's a straight 3-pole thermal-magnetic with a shunt trip added. Power loss maxes at 57 W, which matters for enclosure heat budgeting. Dimensions: 70 mm deep, 105 mm wide, 158 mm tall.","metaTitle":"Siemens 3VA1225-5EF32-0JA0 SENTRON MCCB, 250 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA1225-5EF32-0JA0 molded case circuit breaker, 250 A continuous, 3-pole, line protection with shunt trip.
