The Siemens 3VA2110-6HK36-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 100 A holds flat through the entire operating band, so a panel designed for a 100 A feeder at 40 °C doesn't lose capacity when the enclosure warms to 65 °C. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V — numbers that place it squarely in high-fault-duty service, typically downstream of a transformer or on a large bus where available fault current exceeds 100 kA. The ETU340 electronic trip unit handles adjustable long-time, short-time, and instantaneous protection curves, so you're not locked into a fixed thermal-magnetic response. The 3-pole, 181 mm × 105 mm × 86 mm (H × W × D) footprint fits standard 3VA2 panel cutouts and bus-bar spacing. Front-face IP40 protection means it's suited for enclosed distribution boards where incidental tool or finger contact is the concern, not washdown environments.
No official successor has been published because none is needed; the 3VA2 platform remains the standard SENTRON MCCB line for distribution and feeder protection.
The 3VA2 mounts via four M6 screws on a rear panel or onto a mounting plate. Bus-bar connection uses standard MCCB lug kits — verify lug tunnel size against your cable or bus rating. The ETU340 draws 10 W maximum power loss, so account for that in enclosure thermal calculations, especially in a densely packed panel. Ground-fault monitoring is also absent on this build; specify a 3VA2 with the G option for that function.
