Product details

The Siemens 3RV2011-0AA20 is a SIRIUS motor protection circuit breaker, size S00, designed to protect motors against overload and short-circuit. Its Trip Class 10 ensures fast tripping under locked-rotor conditions — within 10 seconds at 7.2× rated current — which is the standard for standard-duty induction motors driving pumps, fans, and compressors. The 100 kA breaking capacity at 400 V AC means it can safely interrupt fault currents up to that level without upstream fuses or a larger breaker, simplifying coordination in a distribution panel.

Mounting and integration

Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width (three 17.5 mm modules) fits standard enclosure cutouts, and the 97 mm depth leaves clearance for wiring behind the rail. Spring-loaded terminals on the main circuit accept 2× (0.5 … 4 mm²) solid or stranded — no lug crimping needed, which speeds panel wiring.

Lifecycle and sourcing

The lifecycle stage is listed as current, meaning Siemens still manufactures this order code. No successor has been announced. For a BOM line that calls out 3RV2011-0AA20, this part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

Frequently asked questions

Where can I buy 3RV2011-0AA20 and get a price?

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

Will 3RV2011-0AA20 drop into a panel specified for 3RV2011-0AA10 without rewiring?

Yes, both are size S00 breakers with the same 45 mm width and screw/snap-on DIN rail mounting, so the mechanical fit is identical. The terminal type and wiring capacity are the same (spring-loaded, 2× 0.5–4 mm²). The difference is in the trip setting range — verify the overload setting matches your motor FLA before swapping.

What is the breaking capacity of 3RV2011-0AA20 at 400 V?

100 kA at 400 V AC, which is the same at 240 V, 500 V, and 690 V AC — a flat 100 kA across the common industrial voltages.
