At 690 V the 17 kA still covers most industrial distribution needs. The breaker carries 250 A continuously up to 50 °C ambient. 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. Physical dimensions: 105 mm wide, 158 mm tall, 70 mm deep. The 70 mm depth leaves room for rear busbar connections in a typical distribution cabinet.","metaTitle":"Siemens SENTRON 3VA1225-6EF32-0AA0 MCCB, 250 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1225-6EF32-0AA0 molded case circuit breaker, 250 A rated, 3-pole, TM240 release, 220 kA at 240 V.
