The 3VA2450-7MS32-0AA0 holds its full 500 A rating from 40 °C through 50 °C ambient. 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.
The closest functional peer in the same SENTRON family is the 3VA2216-7MS32-0KC0, but it is a different frame size and rating — verify dimensions and interrupting capacity before substituting. The 3VA2450-7MS32-0AA0 is a 500 A, 3-pole starter-protection MCCB; the 3VA2216-7MS32-0KC0 serves a different current class and may not drop into the same panel cutout without rewiring.
