The Siemens SENTRON 3VA2010-5HN36-0AB0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating needed in a warm panel — the same 100 A holds at 70 °C as at 40 °C. The interrupting ratings climb steeply: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — that 187 kA figure at 240 V covers high-fault utility feeds or transformer secondaries without needing a current-limiting fuse upstream.
SCCR and Selectivity Planning
For a panel designer coordinating with upstream breakers, the 3VA2010-5HN36-0AB0 delivers 121 kA at 415 V and 75.6 kA at 500 V — these are the numbers to use for IEC 60947-2 short-circuit coordination studies. The 3 kA at 690 V is a steep drop but still covers most 690 V distribution fault levels.
