The Siemens 3VA2116-7JQ32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated 160 A continuous from 40 °C all the way up to 70 °C — no derating needed across that span, which simplifies panel thermal budgeting for a line-up of these breakers. The N-conductor protection is adjustable from OFF up to 160 % of the phase rating, useful for sizing the neutral on a 4-wire system. Interrupting ratings: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. That covers most industrial service-entrance and feeder applications where high fault current is expected.
Rated insulation voltage Ui 800 V, operating temperature range -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power loss 25.5 W — factor that into enclosure ventilation if you're packing several breakers side by side.
Communication function is built in (ETU560 supports Modbus RTU via the optional COM module), so this breaker can report trip events, load currents, and alarm status to a PLC or BMS without extra signal wiring.
