The assembly includes one supplied contactor (3RT2028-2AK60) per direction of rotation, mechanically interlocked — no external interlock wiring needed. Rated 18.5 kW at 400 V AC-3 means it handles standard 3-phase induction motors up to that power in reversing duty — conveyors, hoists, winches, and any application needing forward/reverse control. At 480 V the current rating is 34 A, and at 600 V it is 27 A, so the assembly derates with voltage; verify your motor FLA against the curve for your line voltage. Spring-loaded terminals on both the main circuit and the coil accept 2x (1... 10 mm²) solid or 2x (0.5... 2.5 mm²) stranded — no torquing, just strip and push, which speeds wiring in production or field swap. Two instantaneous auxiliary contacts are built in, giving you one N/O and one N/C for status feedback or permissive logic without adding a side-mount block. ## Deployment and environmental context Vibration resistance at AC is 13.5 g / 5 ms and 8.3 g / 10 ms; at DC 15 g / 5 ms and 10 g / 10 ms — suitable for mounting on machinery with moderate shock, like conveyor drives or pump skids. Clearance distances: 6 mm upwards, forwards, downwards, and sideways; 0 mm backwards — plan your DIN-rail spacing so the assembly has room for airflow and wiring access.","metaTitle":"Siemens 3RA2328-8XB30-2AK6 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2328-8XB30-2AK6 SIRIUS reversing contactor assembly, 18.5 kW at 400 V, S0 size, spring-loaded terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"97 mm","Solid":"2x (1 ... 10 mm²)","Width":"90 mm","at AC":"13,5g / 5 ms, 8,3g / 10 ms","at DC":"15g / 5 ms, 10g / 10 ms","title":"3RA2328-8XB30-2AK6","Height":"114 mm","Upwards":"6 mm","Forwards":"6 mm","at 50 Hz":"0.27","at 60 Hz":"0.8 ... 1.1","Backwards":"0 mm","Downwards":"6 mm","At The Side":"6 mm","description":"reversing contactor assembly, AC-3e/AC-3, 38 A, 18.5 kW / 400 V, 3-pole, 110 V AC, 50 Hz / 120 V, 60 Hz, spring-loaded terminal, electrical and mechanical interlock, auxiliary contacts: 2 x 1 NO","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 DIN 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":"S0","Solid Or Stranded":"2x (0.5 ... 2.5 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Reversing contactor assembly","Of Contactor Typical":"10 000 000","at 400 V rated value":"18.5 kW","at 480 V rated value":"34 A","at 50 Hz rated value":"110 V","at 500 V rated value":"18.5 kW","at 60 Hz rated value":"120 V","at 600 V rated value":"27 A","at 690 V rated value":"18.5 kW","Instantaneous Contact":"2","For Main Current Circuit":"spring-loaded terminals","at 220/230 V rated value":"10 hp","at 460/480 V rated value":"25 hp","at 575/600 V rated value":"25 hp","Per Direction Of Rotation":"1","1 Of The Supplied Contactor":"3RT2028-2AK60","2 Of The Supplied Contactor":"3RT2028-2AK60","at AC-3 rated value maximum":"690 V","at AC-3e rated value maximum":"690 V","at AC-4 at 400 V rated value":"11 kW","Substance Prohibitance (Date)":"10/01/2009","at AWG cables for main contacts":"1x (18 ... 8)","of the supplied RS assembly kit":"3RA2923-2AA2","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: 50 A","At Contactor For Auxiliary Contacts":"Spring-type terminals","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 125 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":"AC","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/b661b81ea7d81788a7661c218316281c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=180462&mlfb=3RA2328-8XB30-2AK6"},"ai":{"faq":[{"question":"What is the price of Siemens 3RA2328-8XB30-2AK6?","answer":"Pricing for the 3RA2328-8XB30-2AK6 is confirmed at quote time based on current market conditions and quantity.
