The Siemens SENTRON 3VA2010-6HN32-0AG0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C — no derating needed across that ambient span. Breaking capacity hits 242 kA at 240 VAC, 187 kA at 415 V, and still holds 121 kA at 500 V. That SCCR headroom means it can sit upstream of a high-fault panel without cascading, which simplifies coordination studies on a distribution board.
At 690 V the breaking capacity drops to 3 kA — that is the limit for a 690 V feeder. If your line runs 480 V, the 187 kA figure gives plenty of margin for most industrial services. Power loss is 13.5 W maximum — negligible for panel thermal budgeting but worth noting if you are packing breakers tight in a non-ventilated enclosure.

That depth is the body only — add projection for the rotary handle and terminals. Trip indicator present on the front face for quick fault isolation.
