The Siemens SENTRON 3VA2010-6HN32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current (Iu) at 40 °C, with a breaking capacity of 242 kA at 240 V and 187 kA at 415 V — numbers that tell you this breaker handles high-fault-current industrial feeds without cascading upstream.
The base switch assembly is order code 3VA2010-6HN32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB25 — useful if you're stocking spares or rebuilding a failed unit.
Panel fit and thermal derating
At 40 °C it carries the full 100 A; at 55 °C it derates to 96.25 A, and at 70 °C to 85 A. Plan your enclosure ventilation if the ambient runs hot — the max power loss is 16 W.
