The spring-loaded terminals accept 2x 0.5 to 2.5 mm² solid or stranded, so you're not fighting screw clamps on a midnight startup. The 3RV2011-4AA20-0BA0 offers a rated short-circuit breaking capacity of 30 kA at 400 V AC (Icu), with an Ics of 55 kA at the same voltage. That's a 1.8x ratio — the Ics exceeds Icu, unusual for this class, meaning it can clear a fault and still be reused in most cases without derating the circuit. The gG fuse backup ratings at 400 V (63 A), 500 V (50 A), and 690 V (40 A) give you a selectivity window for upstream protection. Spring-loaded terminals on the main circuit accept 2x 0.5 to 2.5 mm² solid or stranded — tool-free push-in for the power wiring, which shaves a minute per connection on the panel build. The screwdriver shaft diameter is 3 mm for the auxiliary terminal screws. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the side, 0 mm forwards and backwards — so you can butt it against the back panel and adjacent breakers without extra spacing. That's tight packing for a 45 mm wide device.","metaTitle":"Siemens SIRIUS 3RV2011-4AA20-0BA0 Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2011-4AA20-0BA0 motor protection circuit breaker, Class 10 trip, S00 frame, 4 kW at 230 V, 30 kA at 400 V, spring-loaded terminals, screw and snap-on DIN rail mou","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"Depth":"97 mm","Width":"45 mm","Height":"106 mm","Upwards":"50 mm","Forwards":"0 mm","at 400 V":"gG 63 A","at 500 V":"gG 50 A","at 690 V":"gG 40 A","Backwards":"0 mm","Downwards":"50 mm","Trip Class":"CLASS 10","At The Side":"30 mm","Rated Value":"20 ... 690 V","During Storage":"-50 ... +80 °C","at AC-3 maximum":"15 1/h","lifecycle_stage":"current","During Operation":"-50 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","Mounting Position":"any","Solid Or Stranded":"2x (0.5 ... 2.5 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Circuit breaker","at 230 V rated value":"4 kW","at 240 V rated value":"100 kA","at 400 V rated value":"30 kA","at 500 V rated value":"5 kA","at 690 V rated value":"2 kA","Design Of The Product":"For motor protection","Ground Fault Detection":"No","Phase Failure Detection":"Yes","For Main Current Circuit":"spring-loaded terminals","at AC at 240 V rated value":"100 kA","at AC at 400 V rated value":"55 kA","at AC at 500 V rated value":"10 kA","at AC at 690 V rated value":"4 kA","Design Of Screwdriver Shaft":"Diameter 3 mm","Size Of The Circuit-Breaker":"S00","Size Of The Screwdriver Tip":"3,0 x 0,5 mm","at AC-3 rated value maximum":"690 V","Of The Main Contacts Typical":"500","at AC in hot operating state":"9.25 W","at AC-3 at 400 V rated value":"16 A","Of Auxiliary Contacts Typical":"500","Substance Prohibitance (Date)":"10/01/2009","Design Of The Overload Release":"thermal","Operating Frequency Rated Value":"50 ... 60 Hz","Operational Current Rated Value":"16 A","Design Of The Short-Circuit Trip":"magnetic","For Auxiliary And Control Circuit":"spring-loaded terminals","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","Display Version For Switching Status":"Handle","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"3.1 W","With Side-By-Side Mounting At The Side":"0 mm","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²)","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","Finely Stranded Without Core End Processing":"2x (0.5 ... 1.5 mm²)","number of CO contacts for auxiliary contacts":"0","number of NC contacts for auxiliary contacts":"0","number of NO contacts for auxiliary contacts":"0","shock resistance according to IEC 60068-2-27":"25g / 11 ms","Electrical Endurance (Operating Cycles) Typical":"500","Size Of Contactor Can Be Combined Company-Specific":"S00, S0","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Arrangement Of Electrical Connectors For Main Current Circuit":"Top and bottom","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"208 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"10 ... 16 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=641202&mlfb=3RV2011-4AA20-0BA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RV2011-4AA20-0BA0/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for 3RV2011-4AA20-0BA0?","answer":"The closest functional peer is the 3RV2021-4CA25, which is also an S00 frame motor protection breaker with Class 10 trip. The key difference is that the 3RV2021-4CA25 has a higher rated current — 25 A vs the 3RV2011-4AA20-0BA0's 20 A range — so it covers a larger motor. Both share the same 45 mm width and snap-on DIN rail mounting, so they drop into the same panel footprint."},{"question":"Will 3RV2011-4AA20-0BA0 drop into a panel that was specified around 3RV2021-4CA25 without rewiring?","answer":"Yes, both are S00 frame size with identical 45 mm width, 97 mm depth, and screw/snap-on DIN rail mounting. The terminal layout and spring-loaded connection are the same, so it's a mechanical swap. Just verify the current rating matches your motor — the 3RV2021-4CA25 is a higher-current variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2011-4AA20-0BA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RV2011-4AA20-0BA0 when reusing this data.
