Screw and snap-on mounting means you can pre-wire it on the bench and clip it onto the rail, or mount it directly to a backplate with screws if the rail is full. It carries 2 normally-open instantaneous contacts — no leading, lagging, or delayed switching here. That's a straightforward pair of NO contacts for signaling or pilot-duty switching in a motor starter or control circuit. ## Ratings that matter on site The contact rating at 24 V is 10 A — that's the figure that governs most PLC output and relay coil switching in a typical 24 VDC control loop. At 110 V it drops to 1 A, at 230 V it's 6 A, and at 400 V it's 3 A. These are the thermal current ratings for the auxiliary contacts, so match them to your load's inrush and steady-state draw. If you're switching dry contacts or low-level signals, this contactor handles it without the oxide-film issues that plague power-rated contacts at low voltage. The shock resistance is 10g for 5 ms and 5g for 10 ms — enough for most industrial machinery but not for heavy off-road equipment. The IP20 front protection means the terminals are finger-safe from the front, but the sides and bottom are open to the panel — standard for a DIN-rail component inside a closed enclosure. ## Wiring and conductor sizes The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid conductors. That covers most control wiring from signal-level pairs up to the heavier 4 mm² for short power runs. No need for ferrules on solid wire, but stranded will want them for a clean termination.","metaTitle":"Siemens 3RH1122-1AN60 SIRIUS Auxiliary Contactor, 45 mm, 2 N","metaDescription":"Siemens SIRIUS 3RH1122-1AN60 auxiliary contactor, size S00, 2 NO contacts, 45 mm wide, IP20 front, screw and snap-on mount, 10 A at 24 V, currently in production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"72 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), 2x 4 mm²","Width":"45 mm","Height":"57.5 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","During Storage":"-55 ... +80 °C","Leading Contact":"0","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"screw and snap-on mounting","Shock Resistance":"10g / 5 ms and 5g / 10 ms","Delayed Switching":"0","Lagging Switching":"0","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","Size Of Contactor":"S00","Product Brand Name":"SIRIUS","Contact Reliability":"one incorrect switching operation of 100 million switching operations (17 V, 1 mA)","Degree Of Pollution":"3","Product Designation":"Auxiliary contactor","at 24 V rated value":"10 A","Of Contactor Typical":"30 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.27 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 50 Hz rated value":"200 V","at 500 V rated value":"2 A","at 60 Hz rated value":"200 ... 220 V","at 690 V rated value":"1 A","Instantaneous Contact":"2","For Auxiliary Contacts":"0","Make-Before-Break Switching":"0","Substance Prohibitance (Date)":"07/01/2006","protection class IP on the front":"IP20","Product Extension Auxiliary Switch":"Yes","Surge Voltage Resistance Rated Value":"6 kV","operational current at AC-12 maximum":"10 A","for AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","reference code according to IEC 81346-2":"K","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","Touch Protection Against Electrical Shock":"finger-safe","with low demand rate according to SN 31920":"40 %","Of Auxiliary Contacts Instantaneous Contact":"0","apparent holding power of magnet coil at AC":"4.6 VA","apparent pick-up power of magnet coil at AC":"27 VA","with high demand rate according to SN 31920":"75 %","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"2","Type Of Voltage Of The Control Supply Voltage":"AC","Inductive Power Factor With Closing Power Of The Coil":"0.8","Identification Number And Letter For Switching Elements":"22 E","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Required Spacing With Side-By-Side Mounting At The Side":"0 mm","Inductive Power Factor With The Holding Power Of The Coil":"0.27","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","Type Of Electrical Connection For Auxiliary And Control Circuit":"screw-type terminals","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Of The Contactor With Added Electronically Optimized Auxiliary Switch Block Typical":"5 000 000","Design Of The Fuse Link For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 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=524405&mlfb=3RH1122-1AN60","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RH1122-1AN60/alternatives.json"},"ai":{"faq":[{"question":"What is the depth of 3RH1122-1AN60?","answer":"The depth is 72 mm.
