The Siemens SENTRON 3VA2216-8KQ32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current with no derating across the entire -40 °C to 70 °C operating range — that is the headline number for a BOM line. The 800 V rated insulation voltage (Ui) and the short-circuit breaking capacities — 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, 53 kA at 690 V — define where this breaker can be installed without cascading upstream. The ETU860 electronic trip unit provides adjustable time-delay settings (tr from 0.5 to 25 s, tsd up to 0.5 s) plus ground-fault monitoring via summation current formation, which means it can be coordinated downstream for selective tripping in a distribution panel.
The communication function and other measurement function (both confirmed on this variant) allow integration into a higher-level monitoring system, so a controls integrator can pull trip and load data without separate metering.
