The coil is a 24 V 50/60 Hz unit with an integrated varistor surge suppressor, so you don't need to add an external snubber for the control circuit. It mounts via screw or snap-on onto a 35 mm DIN rail per EN 50022, and the spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded wire — no screwdriver torque check needed, which speeds up panel wiring. For reversing or jogging duty (AC-4), the limit drops to 8.5 A at 400 V, so size accordingly if your application cycles the motor under load. The AC-12 rating of 10 A covers resistive and solid-state loads, useful for switching heaters or power supplies. The short-circuit protection requirement is a gL/gG fuse rated 20 A (type 2 coordination), so your panel designer needs to account for that in the feeder. The S00 frame is compact at 45 mm wide, 60 mm tall, and 114 mm deep — it fits a standard 45 mm DIN-rail slot and leaves room for auxiliary contact blocks on the side. The spring-loaded terminals accept 2x (0.25... 2.5 mm²) or 2x (24... 14 AWG) conductors. Strip length is not specified here, but standard practice for spring-cage terminals on this class is 8-10 mm. The front and terminal areas are IP20, so finger-safe in a closed panel.","metaTitle":"Siemens 3RT1017-2CB04-ZW95 SIRIUS Power Contactor, S00, 5.5","metaDescription":"Siemens SIRIUS 3RT1017-2CB04-ZW95 power contactor, size S00, 5.5 kW at 400 V AC-2, 24 V 50/60 Hz coil, spring-loaded terminals, varistor, current lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"114 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 mm","Maximum":"2 000 m","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","Mounting type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Of The Terminal":"IP20","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Size of contactor":"S00","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":"30 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 50 Hz rated value":"24 V","at 500 V rated value":"5.5 kW","at 60 Hz rated value":"24 V","at 690 V rated value":"5.5 kW","Instantaneous Contact":"2","Side-by-side mounting":"Yes","For Main Current Circuit":"spring-loaded terminals","Single Or Multi-Stranded":"2x (0,25 ... 2,5 mm²)","at AC-2 at 400 V rated value":"5.5 kW","at AC-4 at 400 V rated value":"8.5 A","Design of the surge suppressor":"with varistor","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","at AWG conductors for main contacts":"2x (24 ... 14)","With Type Of Coordination 1 Required":"fuse gL/gG: 35 A","Reference code acc. to DIN EN 81346-2":"Q","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","at AWG conductors for auxiliary contacts":"2x (24 ... 14)","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"spring-loaded terminals","at ambient temperature 40 °C rated value":"22 A","Apparent holding power of magnet coil at AC":"4.4 V·A","Apparent pick-up power of magnet coil at AC":"27 V·A","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","Type of voltage of the control supply voltage":"AC","Inductive power factor with closing power of the coil":"0.8","Inductive power factor with the holding power of the coil":"0.27","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","Of The Contactor With Added Electronics-Compatible 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=230829&mlfb=3RT1017-2CB04-ZW95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1017-2CB04-ZW95/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings for this contactor?","answer":"It is rated 5.5 kW at 400 V AC-2, 8.5 A at 400 V AC-4, and 10 A AC-12.
