The Siemens SENTRON 3VA2110-6HN36-0HL0 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. The line-protection design means it's sized for feeder or main breaker duty, not motor branch-circuit protection.
For a panel builder coordinating with upstream gear, those numbers mean you can place this breaker close to a transformer or service entrance and still maintain selectivity — the fault energy gets cleared here, not upstream.
Auxiliary and trip options
That gives you status feedback for a PLC or SCADA — open/closed, trip event, and a separate alarm contact.
