The AC coil draws 37 VA inrush and 5.7 VA holding at 24 V, 50/60 Hz — the holding power is low enough that a standard 24 V control transformer can drive several of these relays without exceeding its VA budget. ## Mounting flexibility and environmental limits The mechanical service life of 30 million operations typical means the relay outlasts the machine it controls in most cyclic applications. For AWG, it takes 2x 20-16 or 2x 18-14, or 2x 12 AWG. ## Lifecycle and sourcing — active production, quoted to order Sourced through independent distribution channels, this part is quoted to order against the BOM quantity.","metaTitle":"Siemens 3RH6122-1AB00 SIRIUS Contactor Relay, 2NO+2NC","metaDescription":"Siemens 3RH6122-1AB00 SIRIUS contactor relay, size S00, 2 NO + 2 NC auxiliary contacts, AC 24 V 50/60 Hz coil, 6 A rated current, screw and snap-on DIN rail","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Width":"45 mm","at AC":"10 000 1/h","at DC":"10 000 1/h","title":"3RH6122-1AB00","Height":"57.5 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","description":"Contactor relay, 2 NO + 2 NC, AC 24 V, 50/60 Hz, size S00, screw terminal","During Storage":"-55 ... +80 °C","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail","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","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), 2x 4 mm²","Product Brand Name":"SIRIUS","Product Designation":"Contactor relay","at 24 V rated value":"6 A","Of Contactor Typical":"30 000 000","at 110 V rated value":"3 A","at 220 V rated value":"1.2 A","at 230 V rated value":"10 A","at 400 V rated value":"3 A","at 50 Hz rated value":"24 V","at 60 Hz rated value":"24 V","at 690 V rated value":"1 A","Substance Prohibitance (Date)":"10/01/2009","Product Extension Auxiliary Switch":"Yes","Surge Voltage Resistance Rated Value":"6 kV","operating frequency at DC-12 maximum":"1 000 1/h","operating frequency at DC-13 maximum":"1 000 1/h","operational current at AC-12 maximum":"6 A","for AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 2x 12","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)","apparent holding power of magnet coil at AC":"5.7 VA","apparent pick-up power of magnet coil at AC":"37 VA","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","Inductive Power Factor With The Holding Power Of The Coil":"0.25","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","Design Of The Fuse Link For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","design of the miniature circuit breaker for short-circuit protection of the auxiliary circuit up to 230 V":"C characteristic: 6 A; 0.4 kA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ed838d8be597a4bac6bb818427ffaf29.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=641359&mlfb=3RH6122-1AB00"},"ai":{"faq":[{"question":"What is the 3RH6122-1AB00 used for?","answer":"It is a contactor relay — an auxiliary switching device that routes control signals to main contactors, PLC outputs, or indicator lamps.
