The SCCR (short-circuit current rating) of the downstream contactor and overload relay is coordinated with this breaker; the 3RV2041 limits the let-through energy so the contactor survives a fault. ## Screw terminals, DIN rail, any position — panel integration The solid/stranded wire range is 2x (2.5... 16 mm²) for the power circuit, with a larger range of 2x (2.5... 50 mm²) or 1x (10... 70 mm²) available for the load side — sized to handle the full 40 A without derating. The control circuit terminals accept 2x (2.5... 16 mm²) solid or stranded. The dimensions are 70 mm wide, 165 mm high, 176 mm deep. ## Active production — quoted to order Submit an RFQ through the storefront for a current commercial offer.","metaTitle":"Siemens 3RV2041-4FA10 MPCB, Class 10, 40A, 65kA@400V","metaDescription":"Siemens 3RV2041-4FA10 SIRIUS motor protection circuit breaker, Class 10 trip, 40 A rated, 65 kA breaking capacity at 400 V AC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Protection Circuit Breakers (MPCB)"],"specifications":{"Depth":"176 mm","Solid":"2x (2.5 ... 16 mm²)","Width":"70 mm","title":"3RV2041-4FA10","Height":"165 mm","Upwards":"150 mm","Downwards":"150 mm","Trip Class":"CLASS 10","At The Side":"30 mm","Rated Value":"20 ... 690 V","description":"Circuit breaker size S3 for motor protection, CLASS 10 A-release 28...40 A N-release 520 A screw terminal Standard switching capacity","During Storage":"-50 ... +80 °C","at AC-3 maximum":"15 1/h","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","at AC-3e maximum":"15 1/h","Mounting Position":"any","Solid Or Stranded":"2x (2,5 ... 50 mm²), 1x (10 ... 70 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Circuit breaker","at 230 V rated value":"7.5 hp","at 240 V rated value":"100 000 A","at 400 V rated value":"30 000 kA","at 480 V rated value":"40 A","at 500 V rated value":"6 000 kA","at 600 V rated value":"40 A","at 690 V rated value":"37 kW","Design Of The Product":"For motor protection","Ground Fault Detection":"No","Phase Failure Detection":"Yes","For Main Current Circuit":"screw-type terminals","at 110/120 V rated value":"3 hp","at 200/208 V rated value":"15 hp","at 220/230 V rated value":"15 hp","at 460/480 V rated value":"30 hp","at 575/600 V rated value":"40 hp","at AC at 240 V rated value":"100 kA","at AC at 400 V rated value":"65 kA","at AC at 500 V rated value":"12 kA","at AC at 690 V rated value":"6 kA","Size Of The Circuit-Breaker":"S3","at AC-3 rated value maximum":"690 V","Of The Main Contacts Typical":"25 000","at AC in hot operating state":"23 W","at AC-3 at 400 V rated value":"40 A","at AC-3e rated value maximum":"690 V","Of Auxiliary Contacts Typical":"25 000","Substance Prohibitance (Date)":"03/01/2017","at AC-3e at 400 V rated value":"40 A","Design Of The Overload Release":"thermal","Operating Frequency Rated Value":"50 ... 60 Hz","Operational Current Rated Value":"40 A","Design Of The Short-Circuit Trip":"magnetic","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","Display Version For Switching Status":"Handle","For Main Contacts For Ring Cable Lug":"4.5 ... 6 N·m","Surge Voltage Resistance Rated Value":"8 kV","at AC in hot operating state per pole":"7.7 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 (2.5 ... 35 mm²), 1x (2.5 ... 50 mm²)","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","with low demand rate according to SN 31920":"50 %","Finely Stranded Without Core End Processing":"2x (10 ... 35 mm²), 1x (10 ... 50 mm²)","For Main Contacts With Screw-Type Terminals":"4.5 ... 6 N·m","with high demand rate according to SN 31920":"50 %","shock resistance according to IEC 60068-2-27":"25g / 11 ms Sinus","Electrical Endurance (Operating Cycles) Typical":"25 000","Size Of Contactor Can Be Combined Company-Specific":"S3","Outer Diameter Of The Usable Ring Cable Lug Maximum":"19 mm","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":"520 A","insulation voltage with degree of pollution 3 at AC rated value":"1 000 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"28 ... 40 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$413.19","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7f7aca5ea19d99e6e6b7770a617768df.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=630120&mlfb=3RV2041-4FA10"},"ai":{"faq":[{"question":"What is the ampere rating of Siemens 3RV2041-4FA10?","answer":"The 3RV2041-4FA10 is rated at 40 A continuous.
