Design Of The ProductFor starter combinations

Product details

The Siemens 3RV2311-1AC10 is a SIRIUS-brand circuit breaker designed specifically for starter combinations — meaning it's built to sit upstream of a contactor in a motor-starting assembly, not as a standalone feeder breaker. Its 100 kA breaking capacity at 400 V AC (also 100 kA at 240 V, 500 V, and 690 V) means it can safely interrupt very high fault currents without cascading damage upstream in the panel — a critical spec when the transformer or bus rating is high.

Any mounting position works. Screw terminals on the main circuit accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm² — M3 thread for the main contacts.

Rating context for the buyer

No ground-fault or phase-failure detection built in — those are handled externally if needed.

Frequently asked questions

What is the breaking capacity of the 3RV2311-1AC10?

100 kA at 240 V, 400 V, 500 V, and 690 V AC — a high-fault-rated device suitable for industrial panels with large upstream transformers.

Where can I buy the 3RV2311-1AC10?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm offer.

Will the 3RV2311-1AC10 fit a panel designed for the 3RV2011-0AA10?

Both are 45 mm wide SIRIUS breakers with screw/snap-on DIN rail mounting, so the footprint is the same. However, the 3RV2311-1AC10 carries a higher 100 kA breaking capacity versus the 3RV2011 series — verify the fault current rating matches your panel's SCCR requirement before substituting.
