Above that it derates linearly: 495 A at 55 °C, 490 A at 60 °C, 485 A at 65 °C, and 480 A at 70 °C. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The case dimensions are 110 mm deep by 138 mm wide by 248 mm high — a standard MCCB footprint that fits most distribution panelboards and motor control center buckets. Maximum power loss is 99 W.","metaTitle":"Siemens 3VA2450-7MS32-0AA0 SENTRON MCCB, 500 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2450-7MS32-0AA0 molded case circuit breaker, 500 A continuous, 3-pole, 110x138x248 mm.
