The 24 V AC/DC coil (50/60 Hz) with spring-loaded terminals on both main and control circuits means no screw tightening on the line — push the conductor in and it's locked. ## Mounting and panel fit — 135 x 114 x 171 mm Snaps onto 35 mm DIN rail or screws directly to the backplate; the 135 mm width, 114 mm height, and 171 mm depth fit a standard S0 footprint with clearance for the RS assembly kit (3RA2923-2BB2) included in the package. Mounting position is standing on a horizontal surface; the unit tolerates 6 mm misalignment in all directions except backward (0 mm), so the rail clip must seat fully before tightening. ## Mechanical endurance and shock ratings Rated 10 million mechanical operations typical — this is the contactor assembly's service life before wear-out, not the electrical endurance under load, which will be lower depending on switching frequency and motor size. Shock resistance is specified at 11.8 g / 5 ms and 7.4 g / 10 ms on AC; 15 g / 5 ms and 10 g / 10 ms on DC — figures that matter for mobile or vibrating equipment where the contactor must not drop out. ## Wiring and conductor sizing Spring-type terminals on the magnet coil and auxiliary circuits eliminate the need for torque wrenches — strip, insert, and the cage clamps the wire. No auxiliary switch or bus communication module is fitted as standard (product extension auxiliary switch: No; product function bus communication: No), so any add-on must be ordered separately. Substance prohibited date of 10/01/2009 aligns with RoHS compliance; the assembly carries the SIRIUS brand designation and is documented for IEC/EN 60947-4-1 applications.","metaTitle":"Siemens 3RA2423-8XF32-2AC2-ZA01 SIRIUS Star-Delta Starter","metaDescription":"Siemens SIRIUS 3RA2423-8XF32-2AC2-ZA01 contactor assembly for star-delta starting, 11 kW at 400 V, 24 V coil, spring terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"171 mm","Solid":"2x (1 ... 10 mm²)","Width":"135 mm","at AC":"11,8g / 5 ms, 7,4g / 10 ms","at DC":"15g / 5 ms, 10g / 10 ms","title":"3RA2423-8XF32-2AC2-ZA01","Height":"114 mm","Upwards":"6 mm","Forwards":"6 mm","at 50 Hz":"0.25","at 60 Hz":"0.28","Backwards":"0 mm","Downwards":"6 mm","At The Side":"6 mm","description":"Contactor assembly for star-delta (wye-delta) start AC-3, 11 kW/400 V, 24 V AC 50/60 Hz, 3-pole, size S0 Spring-type terminals electrical and mechanical interlock 3 NO + 3 NC integrated","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Spring-type terminals","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail","Mounting Position":"standing, on horizontal mounting surface","Size Of Contactor":"S0","Solid Or Stranded":"2x (0.5 ... 2.5 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Contactor assembly for star-delta (wye-delta) start","Of Contactor Typical":"10 000 000","at 400 V rated value":"11 kW","at 50 Hz rated value":"24 V","at 500 V rated value":"15.6 kW","at 60 Hz rated value":"24 V","at 690 V rated value":"19 kW","Instantaneous Contact":"3","For Main Current Circuit":"spring-loaded terminals","1 Of The Supplied Contactor":"3RT2024-2AC20-1AA0","2 Of The Supplied Contactor":"3RT2024-2AC20-1AA0","3 Of The Supplied Contactor":"3RT2024-2AC20-1AA0","Substance Prohibitance (Date)":"10/01/2009","at AWG cables for main contacts":"1x (18 ... 8)","of the supplied RS assembly kit":"3RA2923-2BB2","For Auxiliary And Control Circuit":"spring-loaded terminals","Product Extension Auxiliary Switch":"No","Product Function Bus Communication":"No","With Type Of Assignment 2 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 25 A","At Contactor For Auxiliary Contacts":"Spring-type terminals","operating frequency at AC-3 maximum":"1 000 1/h","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 63 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","operating voltage at AC-3 rated value maximum":"690 V","contact rating of auxiliary contacts according to UL":"A600 / Q600","Of The Supplied Function Module For Wye-Delta Circuits":"3RA2816-0EW20","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/457d26e22f487827ad8ea9de98fe8d1f.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=191004&mlfb=3RA2423-8XF32-2AC2-ZA01"},"ai":{"faq":[{"question":"How do I get pricing and availability for 3RA2423-8XF32-2AC2-ZA01?","answer":"Submit an RFQ against your BOM quantity.
