The Siemens 3VA2010-5HN36-0CA0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous at 40–70 °C — no derating needed across that band, which simplifies panel scheduling in warm cabinets. Line protection design means it's set up for feeder and distribution duty, not motor branch-circuit protection with an integral overload relay. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V — numbers that cover most industrial service-entrance and sub-distribution fault levels without cascading upstream.
No communication function onboard; no ground-fault monitoring module. The breaker is supplied with the basic switch 3VA20105HN360AA0.
Peer comparison — when the panel was specified around 3VA1110-5EF32-0LA0
The 3VA1110-5EF32-0LA0 is a different frame size (likely 160 A or higher) and does not include the undervoltage release. It will not drop into the same panel cutout without rewiring — the mounting hole pattern and busbar centers differ between the 3VA1 and 3VA2 frame families. If your BOM calls for the 3VA2010-5HN36-0CA0, the 3VA1110 is not a mechanical swap.
