Switching frequency at DC is 10,000 cycles per hour — the mechanical recovery time between operations at that rate is the limiting factor, not the coil thermal rise. ## DIN rail fit and panel clearances Clearance distances required: 10 mm upwards, forwards, and downwards from the contactor body, plus 6 mm at the side — plan the gland plate and adjacent device spacing accordingly. ## Environmental ratings for industrial panels Relative humidity minimum is 10% — no upper humidity limit stated, but the pollution degree 3 rating implies the contactor tolerates condensation cycles.","metaTitle":"Siemens 3RH2131-1AV00 SIRIUS Auxiliary Contactor, 10 A","metaDescription":"Siemens 3RH2131-1AV00 SIRIUS auxiliary contactor, 10 A rated at 24/230 V, 400 V insulation, S00 frame, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Width":"45 mm","at AC":"4 ... 15 ms","at DC":"10 000 1/h","title":"3RH2131-1AV00","Height":"57.5 mm","Upwards":"10 mm","Forwards":"10 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"6 mm","description":"Contactor relay, 3 NO + 1 NC, 400 V AC, 50 / 60 Hz, Size S00, screw terminal","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","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","Degree Of Pollution":"3","Product Designation":"Auxiliary contactor","at 24 V rated value":"10 A","at 60 V rated value":"4.7 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 440 V rated value":"0.5 A","at 50 Hz rated value":"400 V","at 500 V rated value":"2 A","at 60 Hz rated value":"400 V","at 600 V rated value":"0.26 A","at 690 V rated value":"1 A","Instantaneous Contact":"3","Relative Humidity Minimum":"10 %","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":"10 A","for AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 2x 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)","with low demand rate according to SN 31920":"40 %","apparent holding power of magnet coil at AC":"5.7 VA","apparent pick-up power of magnet coil at AC":"37 VA","with high demand rate according to SN 31920":"73 %","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"3","Type Of Voltage Of The Control Supply Voltage":"AC","contact rating of auxiliary contacts according to UL":"A600 / Q600","Inductive Power Factor With Closing Power Of The Coil":"0.8","Identification Number And Letter For Switching Elements":"31 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","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","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":"$20.32","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ed049f11ef21f009d557f418f28cff87.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=208398&mlfb=3RH2131-1AV00"},"ai":{"faq":[{"question":"What is the rated current of 3RH2131-1AV00 at different voltages?","answer":"Rated insulation voltage is 400 V at 50/60 Hz."},{"question":"What compliance documentation does Siemens provide for 3RH2131-1AV00?","answer":"RoHS compliance is documented with a substance prohibitance date of 10/01/2009.
