The SENTRON 3VA2110-5KP32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting. The line-protection design means it's tuned for cable and busbar protection, not motor overload curves.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — standard SENTRON 3VA form factor for 100 A frame. The communication function means it can talk to a higher-level system for metering or remote trip indication; the trip indicator gives a local visual. Power loss is 12.5 W max — negligible for enclosure thermal calculations at this frame size.
