It is certified for use in potentially explosive atmospheres under DMT 98 ATEX G 001, making it suitable for integration into Ex-certified motor starter assemblies. ## Electrical and Mechanical Ratings The main current circuit is rated for 3 poles, with screw-type terminals accepting solid conductors of 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), or finely stranded wire with core end processing in the same ranges. AWG equivalents for the main contacts are 2x (20... 16), 2x (18... 14), and 2x 12. Auxiliary and control circuits also use screw-type terminals, with AWG capacity of 2x (20... 16) and 2x (18... 14). The auxiliary contacts are rated for switching at various control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V, among others. Power dissipation per pole is 1.6 W, which should be factored into the thermal budget of the enclosure. ## Environmental and Mounting Specifications The device has an IP20 protection rating on the front, suitable for installation within a locked or tool-accessible enclosure. It is rated for 100% relative humidity during operation. Mounting is via contactor mounting (direct attachment to a compatible SIRIUS contactor). The mounting position allows for a vertical mounting surface with +/-135° rotation and +/-45° tilt to the front and back. The relay is shock-resistant to 8g for 10 ms, per the specification. ## Physical Dimensions and Compliance The physical dimensions are 78 mm depth, 45 mm width, and 87 mm height, fitting the S00 form factor for compact panel layouts. The substance prohibition date per RoHS-like compliance is listed as 07/01/2006.","metaTitle":"Siemens 3RU1116-0FB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-0FB0-ZX95 SIRIUS thermal overload relay, Size S00, Class 10 trip, 3-pole, screw terminals, IP20 front, ATEX certified, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Overload Relays"],"specifications":{"Depth":"78 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Width":"45 mm","Height":"87 mm","Upwards":"0 mm","at 24 V":"1 A","Forwards":"0 mm","Per Pole":"1.6 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","Backwards":"0 mm","Downwards":"0 mm","Trip Class":"CLASS 10","At The Side":"6 mm","During Storage":"-55 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +70 °C","During Transport":"-55 ... +80 °C","Fastening Method":"Contactor mounting","Shock Resistance":"8g / 10 ms","Mounting Position":"with vertical mounting surface +/-135° rotatable, with vertical mounting surface +/- 45° tiltable to the front and back","Product Brand Name":"SIRIUS","Type Of Protection":"DMT 98 ATEX G 001","Product Designation":"thermal overload relay","Size Of Overload Relay":"S00","For Main Current Circuit":"screw-type terminals","Substance Prohibitance (Date)":"07/01/2006","at AWG cables for main contacts":"2x (20 ... 16), 2x (18 ... 14), 2x 12","protection class IP on the front":"IP20","For Auxiliary And Control Circuit":"screw-type terminals","Relative Humidity During Operation":"100 %","Surge Voltage Resistance Rated Value":"6 kV","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14)","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","Touch Protection Against Electrical Shock":"finger-safe","number of CO contacts for auxiliary contacts":"0","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"1","Size Of Contactor Can Be Combined Company-Specific":"S00","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/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":"4.8 W","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.35 ... 0.5 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=8873&mlfb=3RU1116-0FB0-ZX95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RU1116-0FB0-ZX95/alternatives.json"},"ai":{"faq":[{"question":"What is the trip class of this overload relay?","answer":"It is a Class 10 trip relay, designed to trip within 10 seconds at 7.2 times the current setting, suitable for standard motor starting."},{"question":"What certifications does this relay carry?","answer":"It carries ATEX certification DMT 98 ATEX G 001 for use in potentially explosive atmospheres, and has an IP20 protection rating on the front."},{"question":"What are the mounting clearances required?","answer":"The required clearances are 0 mm upwards, forwards, backwards, and downwards, with 6 mm clearance at the side.
