That's the standard for standard-duty motor starting — it lets the motor accelerate through the inrush without nuisance tripping, but still protects against a locked rotor. If your application has a long acceleration time (high-inertia loads like fans or centrifuges), you might need a Class 20 or 30 starter instead. ## Mounting and integration — 45 mm footprint on 35 mm DIN rail This starter mounts on a 35 mm DIN rail via screw and snap-on fastening, with a width of 45 mm — that's a single S00 footprint. The depth is 97 mm, height 167 mm. Clearance requirements: 50 mm above, 20 mm in front, 10 mm below, 20 mm at the sides, zero behind. That 0 mm rear clearance means it can sit flush against a back panel, which helps when you're packing components into a shallow enclosure. The supplied contactor is a 3RT2016-1BB42 and the link module is 3RA1921-1DA00 — so the starter ships as a pre-assembled combination of contactor and overload relay, wired through the link module. The main circuit uses screw-type terminals, which is the standard for panel wiring with ring or fork lugs. Mounting position is vertical only.","metaTitle":"Siemens 3RA2115-1CA16-2BB4-ZX95 SIRIUS Direct Starter","metaDescription":"Siemens 3RA2115-1CA16-2BB4-ZX95 SIRIUS direct (on-line) starter, size S00, 2.5 A at 400 V AC-3, Class 10, 24 V DC 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","Width":"45 mm","title":"3RA2115-1CA16-2BB4-ZX95","Height":"167 mm","Upwards":"50 mm","Forwards":"20 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"20 mm","Rated Value":"24 ... 24 V","description":"Load feeder fuseless, Direct-on-line starting 400 V AC, Size S00 1.8...2.5 A 24 V DC screw terminal for installation on standard mounting rail Type of coordination 2, Iq = 150 kA (also fulfills type of coordination 1) 1 NC (contactor) 1 NO+1 NC (circuit breaker, transverse) Reusable packaging contains 24 units","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail","Mounting Position":"vertical","PROFIsafe protocol":"No","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Product Designation":"Direct (on-line) starter","Size Of Load Feeder":"S00","PROFINET IO protocol":"No","at 230 V rated value":"0.25 hp","at 400 V rated value":"750 kW","at 480 V rated value":"2.5 A","at 600 V rated value":"2.5 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"screw-type terminals","Temperature Compensation":"-20 ... +60 °C","at 110/120 V rated value":"0.1 hp","at 200/208 V rated value":"0.5 hp","at 220/230 V rated value":"0.75 hp","at 460/480 V rated value":"1.5 hp","at 575/600 V rated value":"2 hp","Of The Supplied Contactor":"3RT2016-1BB42","Of The Supplied Link Module":"3RA1921-1DA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","at AC-3 at 400 V rated value":"2.5 A","at AC-3e rated value maximum":"690 V","at AC-3e at 400 V rated value":"2.5 A","Design Of The Overload Release":"thermal (bimetallic)","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-1CA15","degree of protection NEMA rating":"other","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","Without Load Current Share Typical":"4 W","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"2.7 W","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"73 %","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"1","reference code according to IEC 81346-2:2019":"Q","shock resistance according to IEC 60068-2-27":"6g / 11 ms","Type Of Voltage Of The Control Supply Voltage":"DC","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"33 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"1.8 ... 2.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6457c9c65fedeaf45d0e3715ef5adf58.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=140157&mlfb=3RA2115-1CA16-2BB4-ZX95"},"ai":{"faq":[{"question":"Where can I buy 3RA2115-1CA16-2BB4-ZX95 and how do I get a price?","answer":"Submit an RFQ for current pricing and availability — no stock-holding claim is made here."},{"question":"What is 3RA2115-1CA16-2BB4-ZX95's listed depth (97 mm) on this Motor Starters line?","answer":"The depth is 97 mm.
