It mounts in any position and is designed for stand-alone installation, not ganged to a contactor. No screw torque to check — push the ferrule in and the cage holds. ## Class 10 trip and motor power ratings That matches standard motor start profiles for pumps, fans, and compressors where the start time stays under 10 seconds. Current ratings at 480 V and 600 V are both 12.5 A — useful for North American 480 V panels where the motor FLA falls in that range. ## Auxiliary contact switching capacity At 60 V DC it switches 0.3 A, dropping to 0.22 A at 110–125 V DC and 0.11 A at 220 V DC. These are the contact ratings for the trip-signal circuit — the relay's own thermal element handles the motor current. Each pole dissipates 2.2 W at rated current — budget that into the enclosure thermal calculation if multiple relays are stacked. The MTTF at high demand rate is 2,280 years, which reflects a robust electromechanical design for continuous industrial duty. Storage and transport limits are -55 to +80 °C. The relay carries a substance prohibition date of 10/01/2009, aligning with RoHS and REACH compliance requirements.","metaTitle":"Siemens 3RU2116-1KC1 SIRIUS Thermal Overload Relay","metaDescription":"Siemens SIRIUS 3RU2116-1KC1 thermal overload relay, size S00, 5.5 kW at 400 V AC-3e, Class 10 trip, spring-loaded terminals, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Overload Relays"],"specifications":{"Note":"for message \"Tripped\"","Depth":"79 mm","Width":"45 mm","title":"3RU2116-1KC1","Height":"102 mm","at 24 V":"2 A","at 60 V":"0.3 A","Per Pole":"2.2 W","at 110 V":"0.22 A","at 120 V":"3 A","at 125 V":"0.22 A","at 220 V":"0.11 A","at 230 V":"2 A","at 400 V":"1 A","Trip Class":"CLASS 10","Rated Value":"690 V","description":"Overload relay 9.0...12.5 A Thermal For motor protection Size S00, Class 10 Stand-alone installation Main circuit: Spring-type terminal Auxiliary circuit: spring-type terminal Manual-Automatic-Reset","During Storage":"-55 ... +80 °C","lifecycle_stage":"current","During Operation":"-40 ... +70 °C","During Transport":"-55 ... +80 °C","Fastening Method":"stand-alone installation","Mounting Position":"any","Solid Or Stranded":"2x (0.5 ... 2.5 mm²)","Product Brand Name":"SIRIUS","Product Designation":"thermal overload relay","at 400 V rated value":"5.5 kW","at 480 V rated value":"12.5 A","at 500 V rated value":"7.5 kW","at 600 V rated value":"12.5 A","at 690 V rated value":"7.5 kW","Size Of Overload Relay":"S00","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-40 ... +60 °C","MTTF with high demand rate":"2 280 y","Design Of Screwdriver Shaft":"Diameter 3 mm","Size Of The Screwdriver Tip":"3,0 x 0,5 mm","at AC-3e rated value maximum":"690 V","Substance Prohibitance (Date)":"10/01/2009","Design Of The Auxiliary Switch":"integrated","Design Of The Overload Release":"thermal","Operating Frequency Rated Value":"50 ... 60 Hz","Operational Current Rated Value":"12.5 A","at AWG cables for main contacts":"1x (20 ... 12)","For Auxiliary And Control Circuit":"spring-loaded terminals","Between Main And Auxiliary Circuit":"440 V","Relative Humidity During Operation":"10 ... 95 %","Display Version For Switching Status":"Slide switch","Surge Voltage Resistance Rated Value":"6 kV","at AWG cables for auxiliary contacts":"2x (20 ... 14)","Between Auxiliary And Auxiliary Circuit":"440 V","reference code according to IEC 81346-2":"F","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"3","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":"1","number of NO contacts for auxiliary contacts":"1","shock resistance according to IEC 60068-2-27":"8g / 11 ms","operational current at AC-3e at 400 V rated value":"12.5 A","Size Of Contactor Can Be Combined Company-Specific":"S00","contact rating of auxiliary contacts according to UL":"B600 / R300","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Arrangement Of Electrical Connectors For Main Current Circuit":"Top and bottom","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gG: 6 A, quick: 10 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Product Component Removable Terminal For Auxiliary And Control Circuit":"No","power loss [W] for rated value of the current at AC in hot operating state":"6.6 W","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"9 ... 12.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/40f5b6d6110f2418b6cdbbf15cef8ddf.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=348960&mlfb=3RU2116-1KC1"},"ai":{"faq":[{"question":"What does the 'Note for message Tripped' mean on this relay?","answer":"The note indicates that the auxiliary contact position signals the tripped state.
