The Siemens SENTRON 3VA2010-6JQ32-0AA0 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 the 70 °C mark. Its breaking capacity hits 242 kA at 240 V, 187 kA at 415 V, and 121 kA at 500 V, with a steep drop to 3 kA at 690 V.
Sizing and selectivity
The adjustable thermal-magnetic trip unit spans 20 A to 100 A (initial value 20 A, full-scale 100 A). That gives you flexibility to set the pickup for a 20 A feeder or a 100 A main, but the breaker's frame and contacts are built for the 100 A continuous rating.
Panel integration
Communication function is onboard (likely PROFIBUS or PROFINET via a plug-in module), so you can integrate it into a line-side power monitoring scheme without a separate metering block.
