The Siemens SENTRON 3VA2110-8KP36-0AA0 is a 3-pole 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. It carries an ETU850 electronic overcurrent release, configurable for line-protection duty, and includes communication capability for integration into a monitored distribution scheme. The interrupting ratings are the headline: 440 kA at 240 V, 330 kA at 415 V and at 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That puts it in the high-fault tier for industrial mains — think transformer secondaries, large motor control centers, or busway feeds where available fault current runs high.
The ETU850 release supports communication (the listing flags a communication function present), so you can pull trip data and status into a BMS or SCADA layer without adding a separate metering module.
Lifecycle status is listed as current — this is an active catalog item from Siemens, not a phase-out or NRND line. That means factory support, firmware updates (if applicable), and replacement parts are available through normal Siemens distribution channels.
The adjustable release range (minimum 150 A, maximum 1 200 A) suggests the ETU850 can be set for a wide pickup window, though the frame itself is sized for 100 A continuous.
