The relay carries ATEX approval (DMT 98 ATEX G 001), permitting use in potentially explosive atmospheres — a key requirement for tender specifications in chemical, oil & gas, or grain-handling installations. For audit purposes, the ATEX certificate number should be cross-referenced with the installation zone classification. ## Electrical and Environmental Ratings Auxiliary contact ratings are specified across multiple control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V. These figures govern the pilot duty capability — for a 24 VDC PLC input, the 1 A rating is more than sufficient; for a 230 VAC contactor coil, the 2 A rating provides headroom for inrush. The relay withstands 100 % relative humidity during operation — relevant for high-condensation environments like wastewater lift stations. Both main and auxiliary/control circuits use screw-type terminals. The main circuit accepts solid conductors: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), with AWG equivalents of 2x (20... 16), 2x (18... 14), and 2x 12. Finely stranded conductors with core-end processing follow the same cross-section ranges. Auxiliary contacts accept 2x (20... 16) and 2x (18... 14) AWG. Dimensions: 45 mm width, 87 mm height, 78 mm depth.","metaTitle":"Siemens 3RU1116-1DB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1DB0-ZX95 SIRIUS thermal overload relay, Size S00, Class 10 trip, 3-pole, screw terminals, IP20 front, ATEX certified, active 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":"1.9 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":"5.7 W","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"2.2 ... 3.2 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=430753&mlfb=3RU1116-1DB0-ZX95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RU1116-1DB0-ZX95/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for the 3RU1116-1DB0-ZX95?","answer":"The 3RT6023-1BW40 is a contactor, not a direct functional replacement for this thermal overload relay.
