Main circuit termination uses spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded conductors. That saves a screwdriver turn per connection on the panel line, but verify your ferrule size — the upper limit is 2.5 mm² per conductor. The 45 mm width leaves room for a three-phase contactor plus an auxiliary block. ## Mounting and integration — DIN rail, spacing, and coordination Type 1 coordination (contactor may need replacement after fault) allows a 35 A gL/gG fuse. Both values assume the main circuit is protected per IEC 60947-4-1. Coil consumption is 3.3 W DC for both closing and holding — a single-supply DC coil that doesn't spike on pickup. That simplifies the DC supply sizing in a 24 VDC control circuit. ## Lifecycle and sourcing — active production, no end-of-life notice This contactor is a direct drop-in for any panel originally specified with the 3RT1017-2BM42. The spring-loaded terminals and DIN-rail footprint match the existing layout. ## Ratings and environmental limits — what they mean for the panel Pollution degree 3 means the contactor is rated for conductive pollution environments — typical for factory floors with dust and humidity — but not for direct chemical exposure. Above that, the air dielectric and cooling capacity drop; consult the thermal derating curve if your installation is above 2 000 m. Mechanical life is typical 30 000 000 operations — that's the mechanical endurance, not the electrical life under load. Electrical life depends on the switching duty (AC-1, AC-3, AC-4) and the switched current; for AC-2 at 5.5 kW, expect significantly fewer operations before contact wear.","metaTitle":"Siemens 3RT1017-2BM42 SIRIUS Contactor, S00, 5.5 kW AC-2 at","metaDescription":"Siemens SIRIUS 3RT1017-2BM42 power contactor, size S00, 5.5 kW AC-2 at 400 V, spring-loaded terminals, 45 mm wide, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 mm","Maximum":"2 000 m","At The Side":"6 mm","Rated Value":"220 V","On The Front":"IP20","Initial Value":"0.85","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","Full-scale value":"1.1","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 500 V rated value":"5.5 kW","at 690 V rated value":"5.5 kW","Instantaneous Contact":"0","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","Closing power of magnet coil at DC":"3.3 W","Holding power of magnet coil at DC":"3.3 W","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","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","Type of voltage of the control supply voltage":"DC","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=75815&mlfb=3RT1017-2BM42","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1017-2BM42/alternatives.json"},"ai":{"faq":[{"question":"What is the physical size and mounting?","answer":"Width 45 mm, height 60 mm, depth 73 mm.
