Product details

What it is and what the ratings mean

The Siemens 3VA1110-5MH32-0AE0 is a 3-pole IEC molded-case circuit breaker in the 3VA1 series, built on a 160 A frame. Its interrupting capacity is 55 kA at 415 V AC (Icu).

Sourcing and lifecycle

Lifecycle stage is listed as current. Sourcing runs through independent distribution channels; availability and pricing are confirmed at quote time against an RFQ.

Deployment context

The 3VA1 frame mounts on a DIN rail or panel base inside a distribution board or motor control center. The nut keeper kit (included) retains the terminal screws during wiring — a time-saver on repetitive panel builds. Four HQ auxiliary switches are factory-installed, giving you status feedback for the open/closed/tripped positions without additional kit.

Frequently asked questions

What is the interrupting capacity of this MCCB?

The 3VA1110-5MH32-0AE0 is rated Icu = 55 kA at 415 V AC, breaking capacity class M. That figure governs its ability to interrupt a short-circuit fault without damage to the switchboard.

Does this breaker include overload protection?

No. The TM120M trip unit provides only magnetic (short-circuit) protection with an adjustable pickup Ii = 5...15 x In. Overload protection is omitted, so the breaker must be paired with a separate overload relay for motor branch circuits.
