It is designed to switch control signals and auxiliary loads in motor starter and contactor assemblies — the kind of signal-level switching that governs a contactor coil or a PLC input in a panel. The 2 NO contacts are rated for switching at various control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The contacts are instantaneous (no make-before-break or delayed action), so they close and open with the main contactor armature. This makes the 3RH1122-2AB00-0TK1 suitable for switching PLC-level DC signals without the contact wetting issues common on standard power contactors. This aligns with requirements for industrial control panels. RoHS compliance date is noted as July 1, 2006, which aligns with the EU RoHS directive effective date. The product extension for auxiliary switches is marked as Yes, so add-on blocks are available if the 2 NO contacts are insufficient. Dimensions are 45 mm wide, 60 mm high, and 73 mm deep — the S00 footprint that fits standard contactor/relay spacing on DIN rail. The solid conductor capacity is 2x (0.25 to 2.5 mm²), which covers the common control wiring range from signal-level twisted pair to 14 AWG power-limited circuits. Terminal screws accept both solid and stranded wire within that range. Shock resistance is 10g at 5 ms and 5g at 10 ms — adequate for most industrial machinery but not rated for continuous high-G environments like engine test cells without additional damping.","metaTitle":"Siemens 3RH1122-2AB00-0TK1 SIRIUS Auxiliary Contactor, 2 NO","metaDescription":"Siemens SIRIUS 3RH1122-2AB00-0TK1 auxiliary contactor, 2 NO instantaneous contacts, size S00, IP20 front, screw/snap-on mount, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 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":"24 V","at 500 V rated value":"2 A","at 60 Hz rated value":"24 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","at AWG cables for auxiliary contacts":"2x (24 ... 14)","operational current at AC-12 maximum":"10 A","reference code according to IEC 81346-2":"K","Finely Stranded With Core End Processing":"2x (0.25 ... 1.5 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 %","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","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":"Cage Clamp 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=77211&mlfb=3RH1122-2AB00-0TK1","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RH1122-2AB00-0TK1/alternatives.json"},"ai":{"faq":[{"question":"What is the physical size and mounting method?","answer":"It measures 45 mm wide, 60 mm high, and 73 mm deep, fitting the S00 frame size.
