The Siemens 3VA2216-5MN32-0BA0 is a SENTRON molded case circuit breaker (MCCB) in the motor protection version, rated for 160 A continuous current at 40 °C and carrying a 187 kA interrupting capacity at 240 V.
Three-pole design, 160 A frame. The interrupting capacity drops as voltage climbs: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V. It also includes an undervoltage release (UVR), so if your control voltage drops, the breaker opens — no separate undervoltage relay needed.
The depth of 86 mm leaves room for rear-connected busbars or cable lugs in a typical 600 mm deep enclosure.
Environment and approvals
That 70 °C top end means it can sit next to a hot motor starter or transformer without derating the frame — though the ETU350M trip curve may need a second look at elevated temps. Maximum power loss is 75 W. No auxiliary contacts or ground-fault monitoring built in; those are add-on modules. The breaker carries the SENTRON brand, which typically holds UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications — verify the specific listing for your jurisdiction at quote time.
