The Siemens 3VA2110-8KP32-0AA0 is a SENTRON molded case circuit breaker (MCCB) in the 3VA platform, rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the top of the operating band. It carries a 3-pole design with an ETU850 electronic trip unit, meaning the protection curve is programmable and the breaker can communicate status over the integrated communication interface — no separate module required for basic connectivity. Breaking capacity reaches 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that put it squarely in high-fault-current distribution panels where SCCR headroom matters.
Front face carries IP40 protection, so it is suitable for clean indoor panels; the enclosure behind the escutcheon must provide the overall IP rating for the assembly.
Maximum power loss is 7.7 W. Isolation voltage is rated at 800 V.
