It ships with one 3RT2027-1AC20 contactor already supplied; the second contactor is the mirror half of the reversing pair. ## Panel fit and mounting — size S0 constraints The assembly is size S0: 101 mm high, 90 mm wide, 97 mm deep. That flexibility helps when you're squeezing it into a crowded panel. Clearance around the assembly: 6 mm upwards, forwards, downwards, and to the side, but 0 mm backwards (the back sits flat on the rail). That 97 mm depth plus 6 mm forward clearance means you need about 103 mm from the rail to the enclosure door or busbar. ## Wiring and terminal specs — screw terminals, dual conductor capacity That dual-conductor rating saves a terminal block when you need to loop through or parallel feed. The magnet coil also uses screw terminals — no push-in or spring-cage on the coil circuit. Keep that in mind if your shop standardizes on tool-less wiring. ## Duty cycle and mechanical life — 10 million operations Mechanical life is 10 million operations typical for the contactor. At AC-3 maximum switching rate of 750 operations per hour (also 750 for AC-3e), that's over 13,000 hours of continuous cycling at max rate before mechanical wear becomes a concern. Shock and vibration ratings: 13.5 g for 5 ms and 8.3 g for 10 ms on AC; 15 g for 5 ms and 10 g for 10 ms on DC. That's robust enough for most industrial environments short of direct hammer-mill mounting.","metaTitle":"Siemens 3RA2327-8XB30-1AC2 Reversing Contactor Assembly","metaDescription":"Siemens SIRIUS reversing contactor assembly, size S0, rated 15 kW at 400 V AC-3. 24 V AC coil, screw terminals, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"97 mm","Solid":"2x (1 ... 2.5 mm²), 2x (2.5 ... 10 mm²)","Width":"90 mm","at AC":"13,5g / 5 ms, 8,3g / 10 ms","at DC":"15g / 5 ms, 10g / 10 ms","title":"3RA2327-8XB30-1AC2","Height":"101 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, 32 A, 15 kW / 400 V, 3-pole, 24 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","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":"S0","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":"15 kW","at 480 V rated value":"27 A","at 50 Hz rated value":"24 V","at 500 V rated value":"15 kW","at 60 Hz rated value":"24 V","at 600 V rated value":"27 A","at 690 V rated value":"18.5 kW","Instantaneous Contact":"2","For Main Current Circuit":"screw-type terminals","at 220/230 V rated value":"10 hp","at 460/480 V rated value":"20 hp","at 575/600 V rated value":"25 hp","Per Direction Of Rotation":"1","1 Of The Supplied Contactor":"3RT2027-1AC20","2 Of The Supplied Contactor":"3RT2027-1AC20","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":"2x (16 ... 12), 2x (14 ... 8)","of the supplied RH assembly kit":"3RA2923-2AA1","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: 50 A","At Contactor For Auxiliary Contacts":"Screw-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 ... 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","Contact Reliability Of Auxiliary Contacts":"< 1 error per 100 million operating cycles","with low demand rate according to SN 31920":"40 %","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=89594&mlfb=3RA2327-8XB30-1AC2"},"ai":{"faq":[{"question":"What is the depth of 3RA2327-8XB30-1AC2?","answer":"The depth is 97 mm.
