The Siemens SENTRON 3VA2216-5MN32-0AB0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That flat thermal curve simplifies panel sizing: you can load it to 160 A in a warm enclosure without recalculating. Its interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. This is a motor protection design, meaning its trip curve is shaped for motor inrush — it rides through starting current without nuisance tripping, unlike a standard distribution breaker.
Maximum power dissipation is 19.7 W — modest for a 160 A frame, so thermal management in a sealed panel is straightforward.
Built-in Auxiliary Switches and Trip Options
The trip indicator is not present — you'll rely on the auxiliary switch or handle position for status. No voltage trip trigger is built in.
