These clearances ensure adequate arc-quenching space for the 10-15 ms arcing time. ## Electrical ratings and switching capacity Rated operational voltage is 400 V at 50 Hz and 400-440 V at 60 Hz. Contact ratings vary by voltage: 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 10 A at 230 V, 3 A at 400 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. The contactor handles AC switching with arcing times of 4-15 ms and DC switching up to 10,000 operations per hour. Pollution degree 3. Relative humidity minimum 10%. RoHS compliance date is 10/01/2009. The part is in current lifecycle stage.","metaTitle":"Siemens 3RH2140-4AR60 SIRIUS Auxiliary Contactor, 4 NO, 10 A","metaDescription":"Siemens SIRIUS 3RH2140-4AR60 auxiliary contactor, size S00, 4 instantaneous NO contacts, 10 A at 230 V, 73 mm depth, 45 mm width, screw and snap-on DIN rail mounting, current lifec","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Width":"45 mm","at AC":"4 ... 15 ms","at DC":"10 000 1/h","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","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","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 ... 440 V","at 600 V rated value":"0.26 A","at 690 V rated value":"1 A","Instantaneous Contact":"4","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","reference code according to IEC 81346-2":"K","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 NO contacts for auxiliary contacts":"4","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":"40 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":"ring terminal lug connection","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e65a583b8b421f436da8483bbe05e8de.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=125239&mlfb=3RH2140-4AR60","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RH2140-4AR60/alternatives.json"},"ai":{"faq":[{"question":"What is 3RH2140-4AR60's listed depth?","answer":"The depth is 73 mm, with a width of 45 mm and height of 57.5 mm."},{"question":"What compliance documentation does this brand provide for 3RH2140-4AR60?","answer":"RoHS compliance is documented with a substance prohibition date of 10/01/2009.
