The Siemens SENTRON 3VA2010-7KP46-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band, which simplifies panel schedules in warm enclosures. The ETU850 electronic trip unit handles line protection duty with communication and measurement functions onboard, so it reports current draw and trip events back to the control system without a separate metering module.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number published here.
The peer 3VA2110-8HN32-0AA0 shares the same 4-pole, 100 A frame and ETU850 trip platform, but it carries a different breaking capacity curve and accessory configuration. Verify the SCCR requirements and auxiliary contact count before substituting — the footprint is the same, but the protection coordination may shift.
