It ships with two 3RT2047-1AL20 contactors already installed and wired, saving panel build time. The 150 mm width and 152 mm depth fit standard 600 mm deep enclosures with room for gland plates. Clearance: 10 mm upwards, forwards, downwards, and to the side; 0 mm backwards. That 0 mm rear clearance means it can sit flush against the back panel, useful when you need to stack devices tightly. Listed as current production. This is a standard SIRIUS catalog item, not a phase-out or NRND part. Compliance: RoHS substance prohibition date 03/01/2017 applies.","metaTitle":"Siemens 3RA2347-8XB30-1AL2 Reversing Contactor Assembly","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2347-8XB30-1AL2, 55 kW at 400 V AC-3, 150x160x152 mm, screw and snap-on DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"152 mm","Width":"150 mm","at AC":"10.6 g / 5 ms, 6.3 g / 10 ms","title":"3RA2347-8XB30-1AL2","Height":"160 mm","Upwards":"10 mm","Forwards":"10 mm","at 50 Hz":"0.35","at 60 Hz":"0.41","Backwards":"0 mm","Downwards":"10 mm","At The Side":"10 mm","description":"reversing contactor assembly, AC-3e/AC-3, 110 A, 55 kW / 400 V, 3-pole, 230 V AC, 50/60 Hz, screw terminal, electrical and mechanical interlock, auxiliary contacts: 2 x 1 NO","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","lifecycle_stage":"current","During Operation":"60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting 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":"S3","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Reversing contactor assembly","Of Contactor Typical":"10 000 000","at 400 V rated value":"55 kW","at 480 V rated value":"96 A","at 50 Hz rated value":"230 V","at 500 V rated value":"75 kW","at 60 Hz rated value":"230 V","at 600 V rated value":"99 A","at 690 V rated value":"90 kW","Instantaneous Contact":"2","For Main Current Circuit":"screw-type terminals","at 200/208 V rated value":"30 hp","at 220/230 V rated value":"40 hp","at 460/480 V rated value":"75 hp","at 575/600 V rated value":"100 hp","Per Direction Of Rotation":"1","1 Of The Supplied Contactor":"3RT2047-1AL20","2 Of The Supplied Contactor":"3RT2047-1AL20","at AC-4 at 400 V rated value":"55 kW","Substance Prohibitance (Date)":"03/01/2017","at AWG cables for main contacts":"2x (10 ... 1/0), 1x (10 ... 2/0)","of the supplied RS assembly kit":"3RA2943-2AA1","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","Product Function Bus Communication":"Yes","With Type Of Assignment 2 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 200 A","At Contactor For Auxiliary Contacts":"Screw-type terminals","operating frequency at AC-3 maximum":"850 1/h","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 355 A","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14)","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"3","with low demand rate according to SN 31920":"40 %","Finely Stranded Without Core End Processing":"2x (10 ... 35 mm²), 1x (10 ... 50 mm²)","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"73 %","Type Of Voltage Of The Control Supply Voltage":"AC","operating voltage at AC-3 rated value maximum":"1 000 V","contact rating of auxiliary contacts according to UL":"A600 / Q600","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","product function control circuit interface with IO link":"No","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gG: 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c2e80322f9675498523823a1a9ce72df.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=629715&mlfb=3RA2347-8XB30-1AL2"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2347-8XB30-1AL2","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RA2347-8XB30-1AL2 when reusing this data.
