The Siemens SENTRON 3VA2110-7MN32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that span, which simplifies panel layout in warm enclosures. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Maximum power loss is 10 W.
Yes, it comes with 1 auxiliary switch and 1 trip alarm switch (HQ design) integrated, so you get status feedback without a separate add-on module.
