The relay mounts directly onto a contactor (contactor mounting), saving DIN-rail space and keeping the power loop short — common in motor starter assemblies inside control panels. The S2 frame size handles motor currents in the mid-range of the SIRIUS family — check the specific current setting range on the relay nameplate to confirm it covers your motor FLA. Screw-type terminals on both the main and auxiliary circuits accept stranded wire up to 35 mm² on the mains and 2.5 mm² on the auxiliaries, with solid wire ranges of 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²) respectively — sized for panel wiring with standard ferrule or bare conductors. Power dissipation is 5.2 W per pole; in a three-pole motor circuit that's about 15.6 W total heat to vent inside the enclosure — factor that into your panel thermal budget. Shock resistance of 8g / 10 ms means it will hold calibration under normal machine vibration; not rated for continuous high-g applications like engine mounts. The ATEX certification (DMT 98 ATEX G 001) means it can be part of a motor starter in a potentially explosive gas atmosphere, provided the rest of the starter assembly also meets the zone requirements.","metaTitle":"Siemens SIRIUS 3RU1136-4GB0-ZX95 thermal overload relay, Cla","metaDescription":"Siemens SIRIUS 3RU1136-4GB0-ZX95 thermal overload relay, Class 10 trip, S2 size, 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":"118 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Width":"55 mm","Height":"105 mm","Upwards":"0 mm","at 24 V":"1 A","Forwards":"0 mm","Per Pole":"5.2 W","Stranded":"2x (0.75 ... 25 mm²), 0.75 ... 35 mm²","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":"S2","For Main Current Circuit":"screw-type terminals","Substance Prohibitance (Date)":"07/01/2006","at AWG cables for main contacts":"2x (18 ... 3), 1x (18 ... 1)","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":"S2","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":"15.6 W","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"36 ... 45 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=370851&mlfb=3RU1136-4GB0-ZX95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RU1136-4GB0-ZX95/alternatives.json"},"ai":{"faq":[{"question":"What wire sizes does it accept on the main and auxiliary terminals?","answer":"Main circuit screw terminals accept stranded wire from 0.75 to 35 mm² (2x 0.75…25 mm²) and solid wire 2x (0.5…1.5 mm²).
