The Siemens SENTRON 3VA2216-5KQ32-0BB0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across its full ambient temperature range of -25 °C to 70 °C — no derating needed from 40 °C through 70 °C, which simplifies panel sizing in warm environments. Breaking capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V. Communication function is onboard, so it can talk to a higher-level system for monitoring or load-shedding coordination.
The 160 A full-scale rating with the adjustable thermal-magnetic trip unit (initial value 32 A, full-scale 160 A) lets you set the continuous pickup to match the downstream load — conveyor motor, pump, or feeder circuit.
