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. That 187 kA figure at 240 V tells you it's built for high-fault industrial services where a standard MCCB would weld shut.
Mounts in a standard panel footprint: 105 mm wide, 181 mm tall, 86 mm deep. The 3-pole block leaves room for the three auxiliary switches (HQ type) that ship with it. No undervoltage release, no ground-fault monitoring, no communication module — this is a straight motor-protection MCCB with phase failure detection built in. 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. No trip indicator on the front, so fault diagnosis will rely on the aux contacts or an upstream indication relay.
