It uses the ETU350M electronic overcurrent release with phase-failure detection built in. The continuous current holds at 100 A from 40 °C up to 50 °C ambient, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. The maximum power loss is 75 W, so factor that into the enclosure thermal budget.
The width of 105 mm is standard for a 3-pole 100 A frame in the SENTRON 3VA line.
The depth is 86 mm from the mounting surface to the front of the breaker.
Yes, the 105 mm width is common across the 3VA1 and 3VA2 frames at this rating, so the footprint matches without bus-bar or wiring changes.
