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. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault utility feeds without cascading upstream. The line-protection design means it's sized for feeder or main breaker duty, not motor branch-circuit protection.
Interrupting capacity and selectivity
The 242 kA at 240 V and 187 kA at 415 V are the short-circuit current ratings (SCCR) this breaker can safely interrupt. 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. At 690 V the rating drops to 3.7 kA, which is typical for a 100 A frame at that voltage. If your system runs 690 V, verify the available fault current stays under that threshold.
Auxiliary and trip options
This variant ships with a shunt trip (STL) release for remote tripping, plus two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ configuration). That gives you status feedback for a PLC or SCADA — open/closed, trip event, and a separate alarm contact. The trip indicator and voltage trigger are built in.
Physical fit and environment
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. That's a standard 3-pole MCCB footprint for a 100 A frame — drops into a SENTRON panelboard or a DIN-rail adapter without reworking the backplate. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Power loss at rated current is 10 W, which matters for thermal coordination inside a sealed enclosure.
