Design Of The ProductFor starter combinations

Product details

The Siemens 3RV2311-0AC20 is a SIRIUS circuit breaker specifically designed for starter combinations, not a general-purpose feeder breaker.

Any mounting position works, but allow 50 mm clearance upward and downward, 30 mm to the sides, and zero forward or backward. The 45 mm width means three of these fit in a standard 140 mm DIN rail segment with room for a terminal block.

Wiring and connections

The screwdriver shaft for the auxiliary terminals is 3 mm diameter, tip size 3.0 x 0.5 mm. Strip length isn't listed, but 8 mm is standard for this terminal class.

Environmental limits

The storage range exceeds the operating range — that's handling, not running.

Frequently asked questions

Will 3RV2311-0AC20 drop into a panel specified around 3RV2011-0BA20?

Both are size S00 SIRIUS circuit breakers on the same 45 mm DIN-rail footprint with spring-loaded terminals, so mechanical fit and wiring are identical. The key difference is the 3RV2311-0AC20 is designed specifically for starter combinations, while the 3RV2011-0BA20 is a general-purpose motor-protective breaker. Check the coordination with your contactor and overload — the 3RV2311's trip curve is tuned for starter assembly coordination.
