This Siemens SENTRON 3VA2216-5MN32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full -25 °C to 70 °C operating range — no derating needed as the panel warms up. Interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V.
The 3-pole block leaves room for the three auxiliary switches (HQ type) that ship with it. Max power loss runs 19.7 W, so factor that into your enclosure heat budget.
The basic switch variant is order code 3VA2216-5MN32-0AA0 — this -0AD0 adds the three HQ auxiliary switches.
