Auxiliary and control circuit terminals are spring-loaded, which speeds wiring on the control side and holds well under vibration in a panel. For Type 1 coordination (allow contactor replacement after fault), the fuse can be 63 A. That gives the panel designer flexibility on selectivity with downstream motor protection. ## Environmental and mounting fit The contactor is rated IP20 on the front of the enclosure and IP00 at the terminals — meaning the terminal area is not finger-safe, so it needs to live inside a panel with a door or cover. Dimensions are 45 mm wide, 88 mm high, and 140 mm deep. ## Auxiliary contact and surge suppression The contactor includes 2 instantaneous auxiliary contacts. The surge suppressor is built with RC elements, which limits coil voltage spikes on dropout — relevant if the control circuit shares a DC supply with electronics like a PLC output. Auxiliary contact ratings are given for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are the DC-13 (inductive) values, so they govern the contact life when switching small relays or contactor coils directly.","metaTitle":"Siemens 3RT1024-3XG28-0MV0-ZX95 SIRIUS Power Contactor, Size","metaDescription":"Siemens SIRIUS 3RT1024-3XG28-0MV0-ZX95 power contactor, Size S0, 5.5 kW at 400 V AC-3, 12.5 A AC-4, screw/snap-on DIN rail, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"140 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"88 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","At The Side":"6 mm","On The Front":"IP20","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","Of The Terminal":"IP00","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Size Of Contactor":"S0","Solid Or Stranded":"2x (1 ... 2,5 mm²), 2x (2,5 ... 6 mm²), max. 2x 10 mm²","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"power contactor","at 24 V rated value":"10 A","at 60 V rated value":"2 A","Of Contactor Typical":"10 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 400 V rated value":"5.5 kW","at 50 Hz rated value":"110 V","at 500 V rated value":"7.5 kW","at 60 Hz rated value":"110 V","at 690 V rated value":"7.5 kW","Instantaneous Contact":"2","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-2 at 400 V rated value":"5.5 kW","at AC-4 at 400 V rated value":"12.5 A","Design Of The Surge Suppressor":"with RC elements","at AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 10), 1x 8","For Auxiliary And Control Circuit":"spring-loaded terminals","With Type Of Assignment 2 Required":"fuse gL/gG: 25 A","reference code acc. to IEC 81346-2":"Q","With Type Of Coordination 1 Required":"fuse gL/gG: 63 A","operational current at AC-12 maximum":"10 A","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","Finely Stranded With Core End Processing":"2x (0.25 ... 1.5 mm²)","Number Of Poles For Main Current Circuit":"3","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","at ambient temperature 40 °C rated value":"40 A","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","apparent holding power of magnet coil at AC":"8.4 V·A","apparent pick-up power of magnet coil at AC":"64 V·A","Type Of Voltage Of The Control Supply Voltage":"AC","operational current at AC-15 at 230 V rated value":"6 A","operational current at AC-15 at 400 V rated value":"3 A","Inductive Power Factor With Closing Power Of The Coil":"0.72","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.24","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","type of connectable conductor cross-sections at AWG cables for auxiliary contacts":"2x (24 ... 14)","Of The Contactor With Added Electronically Optimized Auxiliary Switch Block Typical":"5 000 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=239039&mlfb=3RT1024-3XG28-0MV0-ZX95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1024-3XG28-0MV0-ZX95/alternatives.json"},"ai":{"faq":[{"question":"What are the key motor ratings for this contactor?","answer":"AC-3 motor rating is 5.5 kW at 400 V. AC-4 rating is 12.5 A at 400 V. It also carries ratings at 500 V (7.5 kW) and 690 V (7.5 kW) for higher-voltage motor circuits."},{"question":"How does this compare to the 3RT1017-1AP01?","answer":"The 3RT1017-1AP01 is a smaller Size S00 frame contactor with lower motor ratings (typically up to 3 kW at 400 V AC-3). The 3RT1024 in Size S0 is the next frame up, so it won't drop into a panel wired for S00 without re-drilling the mounting holes or using an adapter plate. The terminal spacing and rail footprint are different."},{"question":"What compliance documentation is available for this part?","answer":"The evidence does not list specific compliance certifications (UL, CSA, CE, RoHS) for this exact order code. The SIRIUS family typically carries CE marking for the European market and UL/CSA for North America, but verify the specific variant's markings on the nameplate or request the declaration of conformity from the supplier."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1024-3XG28-0MV0-ZX95","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/3RT1024-3XG28-0MV0-ZX95 when reusing this data.
