Product details

Switch disconnector, not a breaker — what that means for your BOM

The Siemens 3VA1112-1AA32-0CC0 is a 3-pole switch disconnector in the SENTRON 3VA family, rated for 125 A continuous current on an IEC frame 160. Unlike a molded-case circuit breaker, this part provides no overload or short-circuit protection — it is a load-break disconnect for isolation and switching duty. The 125 A rating means it handles full-load current for motor circuits, panel feeders, or distribution branches where protection is handled upstream or by a separate device.

Footprint and panel fit — same 3VA frame, same cutout

At 70 mm deep, 76.2 mm wide, and 130 mm tall, this switch disconnector shares the same 3VA frame dimensions as the equivalent molded-case breaker variants. Front IP40 protection covers the operator interface. The busbar connection style means it lands directly on vertical or horizontal busbar systems in distribution panels — no lug-terminal adapters needed for the main circuit.

Rated insulation voltage Ui: 800 V. Short-time withstand: 2 kA for 1 s and 0.5 s. Mechanical endurance: 15,000 operations. Power loss: 38 W max.

Frequently asked questions

How do I get current pricing and availability for 3VA1112-1AA32-0CC0?

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

Will 3VA1112-1AA32-0CC0 drop into a panel specified around 3VA1112-5EF32-0CA0 without rewiring?

Yes. Both share the same 70 x 76.2 x 130 mm frame dimensions and front-terminal busbar connection pattern. The disconnect lands on the same busbar cutout and mounting holes as the breaker variant — no panel rework needed.

What is the difference between this switch disconnector and a 3VA molded-case circuit breaker?

This part (3VA1112-1AA32-0CC0) is a switch disconnector only — it provides no overload or short-circuit protection. A 3VA molded-case circuit breaker (e.g., 3VA1112-5EF32-0CA0) includes a thermal-magnetic trip unit for line protection. Both share the same frame, footprint, and 125 A continuous current rating, but the disconnect is intended for isolation and switching where protection is handled separately.
