The Siemens SENTRON 3VA2010-6HN36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across its full operating range of -25 °C to 70 °C — no derating needed up to that ceiling. That 100 A holds steady at 40 °C, 50 °C, even 70 °C, which means you can load it to nameplate in a warm panel without recalculating the thermal curve. Breaking capacity is the headline figure here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. The 3 kA at 690 V looks low by comparison, but that's typical for a 100 A frame at that voltage; the real-world application for this part is at 240–500 V. No trip indicator, no voltage trigger, no communication module, and no ground-fault monitoring built in. This is a straightforward line-protection device, not a multifunction power monitor.
The basic switch assembly inside this breaker is order code 3VA20106HN360AA0 — useful to know if you're ordering spare internal parts or validating a replacement subassembly.
