This saves panel-build time over sourcing and assembling two separate contactors plus a mechanical interlock bracket. The 24 V DC coil keeps the control circuit in the low-voltage safety zone — common on PLC-driven panels where 24 V is the standard I/O rail. ## DIN rail footprint and wiring — S00 size with spring terminals The assembly measures 90 mm wide by 84 mm tall by 83 mm deep — the S00 contactor frame size. It snaps onto 35 mm standard mounting rail (screw-fix also supported) and can be rotated +/-180° on a vertical surface or tilted +/-22.5° forward/backward, giving flexibility in tight enclosures. Both the main power circuit and the magnet coil use spring-loaded terminals — no screwdriver needed for the wire connection. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the sides; 0 mm backwards allows flush mounting against the back panel. ## Duty cycle and environmental limits Switching rate maxes at 750 cycles per hour in AC-3 or AC-3e duty — enough for frequent start/stop reversing applications like conveyor shuttles or hoist traverses. Mechanical life is 10 million cycles typical, so the contactor outlasts most machine rebuild intervals. Rated for operation from -25 °C to +60 °C ambient — install it in an unheated panel shed or a washdown area without derating concerns. Storage range is -55 °C to +80 °C. Shock resistance tested at 10.5g for 5 ms and 6.6g for 10 ms, covering both AC and DC coil variants.","metaTitle":"Siemens 3RA2316-8XB30-2BB4 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2316-8XB30-2BB4 SIRIUS reversing contactor assembly, 4 kW at 400 V AC-3, 24 V DC coil, spring terminals, S00 size, active production, quoted to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"83 mm","Solid":"2x (0.5 ... 4 mm²)","Width":"90 mm","at AC":"10,5g / 5 ms, 6,6g / 10 ms","at DC":"10,5g / 5 ms, 6,6g / 10 ms","title":"3RA2316-8XB30-2BB4","Height":"84 mm","Upwards":"6 mm","Forwards":"6 mm","Backwards":"0 mm","Downwards":"6 mm","At The Side":"6 mm","description":"reversing contactor assembly, AC-3e/AC-3, 9 A, 4 kW / 400 V, 3-pole, 24 V DC, spring-loaded terminal, electrical and mechanical interlock","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Spring-type terminals","at AC-3 maximum":"750 1/h","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail","at AC-3e maximum":"750 1/h","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 ... 2.5 mm²)","at DC rated value":"24 V","Product Brand Name":"SIRIUS","Product Designation":"Reversing contactor assembly","Of Contactor Typical":"10 000 000","at 400 V rated value":"4 kW","at 480 V rated value":"7.6 A","at 500 V rated value":"4 kW","at 600 V rated value":"9 A","at 690 V rated value":"5.5 kW","For Main Current Circuit":"spring-loaded terminals","at 200/208 V rated value":"2 hp","at 220/230 V rated value":"3 hp","at 460/480 V rated value":"5 hp","at 575/600 V rated value":"7.5 hp","1 Of The Supplied Contactor":"3RT2016-2BB42","2 Of The Supplied Contactor":"3RT2016-2BB42","at AC-3 rated value maximum":"690 V","at AC-3e rated value maximum":"690 V","at AC-4 at 400 V rated value":"4 kW","Substance Prohibitance (Date)":"10/01/2009","at AWG cables for main contacts":"1x (20 ... 12)","of the supplied RH assembly kit":"3RA2913-2AA2","For Auxiliary And Control Circuit":"spring-loaded terminals","Product Extension Auxiliary Switch":"Yes","Product Function Bus Communication":"Yes","With Type Of Assignment 2 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 20 A","closing power of magnet coil at DC":"4 W","holding power of magnet coil at DC":"4 W","At Contactor For Auxiliary Contacts":"Spring-type terminals","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 35 A","at AWG cables for auxiliary contacts":"2x (20 ... 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)","Number Of Poles For Main Current Circuit":"3","Contact Reliability Of Auxiliary Contacts":"< 1 error per 100 million operating cycles","with low demand rate according to SN 31920":"40 %","Finely Stranded Without Core End Processing":"2x (0.5 ... 1.5 mm²)","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"75 %","Type Of Voltage Of The Control Supply Voltage":"DC","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":"$60.96","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/582cfd7604d87324f78ed3a59ffe3d28.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=158067&mlfb=3RA2316-8XB30-2BB4"},"ai":{"faq":[{"question":"What are the AC-3 motor ratings for 3RA2316-8XB30-2BB4?","answer":"The maximum AC-3 operating voltage is 690 V."},{"question":"What is the physical size and mounting of 3RA2316-8XB30-2BB4?","answer":"It is a Size S00 assembly measuring 90 mm wide, 84 mm high, and 83 mm deep."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2316-8XB30-2BB4","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/3RA2316-8XB30-2BB4 when reusing this data.
