Product details

Integrator note

The 3VA1163-6MH32-0AC0 is a Siemens 3VA1 IEC frame 160 circuit breaker, 3-pole, with a 63 A magnetic-only release (TM120M, AM). The magnetic trip adjustable 5–15 x In covers motor-start inrush without nuisance tripping; there is no thermal overload element, so a separate overload relay must be wired downstream for motor protection.

The magnetic-only release (TM120M) provides short-circuit and ground-fault protection only; since In = 63 A and the thermal element is omitted, it relies on a separate overload relay for motor thermal protection. The 2 auxiliary switches (HQ) and nut keeper kit are factory-fitted, saving panel-builder wiring time.

Frequently asked questions

How do I get pricing and availability for 3VA1163-6MH32-0AC0?

Submit an RFQ. This part is sourced to order through independent distribution; current pricing and lead time are confirmed at quote time.

What is the closest alternative to 3VA1163-6MH32-0AC0 in the 3VA1 family?

Within the same 3VA1 IEC frame 160 family, a variant with a thermal-magnetic release (TM) instead of magnetic-only would add overload protection. The magnetic-only version here is chosen when a separate overload relay handles the thermal curve — typical for motor starter assemblies.
