The vertical mounting position is specified, so plan the gland plate accordingly — the 170 mm height and 90 mm width leave 97.1 mm of depth into the enclosure. Clearance around the unit matters: 20 mm upwards, 10 mm downwards, 9 mm at the side, and zero forwards or backwards. That 20 mm top gap is the one most panels skimp on — without it the bimetallic overload can't shed heat properly. The supplied contactor is a 3RT2015-1BB42, and the link module is 3RA1921-1DA00 — both are captive in the assembly, so there's no separate ordering for the reversing interlock. ## Motor duty and thermal protection Rated AC-3 (motor switching) up to 690 V, 50-60 Hz. At 400 V it's rated 2 200 W, at 500 V it's 3 000 W. The current at 480 V is 4.8 A, at 600 V it's 6.1 A — these are the numbers to use for conductor sizing and SCCR coordination. Assignment type 1 coordination means the starter can be used on a circuit with a short-circuit protective device sized per the manufacturer's tables, without damage to the starter beyond acceptable limits. Pollution degree 3 suits industrial environments with conductive dust or moisture. ## Coil voltage and wiring The coil is 24 V — no suffix for AC/DC is stated, but the SIRIUS 3RA2 series typically uses a universal coil that handles both. Operating temperature range is -20 to +60 °C, storage is -50 to +80 °C, transport is -55 to +80 °C — fine for most panel environments but check if the panel ambient near a hot process exceeds 60 °C. ## Current production — sourcing posture Sourced to order against BOM quantities.","metaTitle":"Siemens 3RA2215-1GA15-2BB4 SIRIUS Motor Starter, Reversing","metaDescription":"Siemens 3RA2215-1GA15-2BB4 SIRIUS non-fused reversing motor starter, size S00, 24 V coil, Class 10 thermal overload, AC-3 rated to 690 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"97.1 mm","Width":"90 mm","title":"3RA2215-1GA15-2BB4","Height":"170 mm","Upwards":"20 mm","Forwards":"0 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"9 mm","Rated Value":"24 V","description":"Fuseless motor starter Reversing operation 600VAC Size S00 4.5-6.3A 24V DC screw connection For screw mounting Or 35 mm rail-mounting Type of coordination 1 1NO+1NC (MSP) 1NC (per contactor)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"Snap-mounted to DIN rail or screw-mounted with additional push-in lug","Mounting Position":"vertical","Product Brand Name":"SIRIUS","Type Of Assignment":"1","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S00","at 230 V rated value":"0.5 hp","at 400 V rated value":"2 200 W","at 480 V rated value":"4.8 A","at 500 V rated value":"3 000 W","at 600 V rated value":"6.1 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"0.25 hp","at 200/208 V rated value":"1 hp","at 220/230 V rated value":"1.5 hp","at 460/480 V rated value":"3 hp","at 575/600 V rated value":"5 hp","Of The Supplied Contactor":"3RT2015-1BB42","For Main Contacts Stranded":"0.5 ... 4 mm², 2x (0.75 ... 2.5 mm²)","Of The Supplied Link Module":"3RA1921-1DA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","Design Of The Overload Release":"thermal (bimetallic)","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","at AWG cables for main contacts":"2x (20 ... 16), only for contactor 2x (18 ... 14), 2x 12","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-1GA15","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"1","shock resistance according to IEC 60068-2-27":"6g / 11 ms","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","operational current at AC-3 at 400 V rated value":"4.9 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"81.9 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":"4.5 ... 6.3 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"0.5 ... 2.5 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b8c673cbc14b4e3ed21729ac146fc6ef.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=30841&mlfb=3RA2215-1GA15-2BB4"},"ai":{"faq":[{"question":"What are the key ratings for the 3RA2215-1GA15-2BB4?","answer":"It is a reversing motor starter, size S00, with a 24 V coil, Class 10 thermal bimetallic overload, AC-3 rated to 690 V, 50-60 Hz.
