It combines a contactor pair for forward/reverse direction switching with a thermal bimetallic overload relay (Class 10 trip class) and a magnetic short-circuit trip in one compact unit — no separate overload relay or contactor assembly needed. The supplied contactor is a 3RT2015-1BB42 and the link module is 3RA1921-1DA00 — these are factory-integrated, not field-assembled. ## Mounting and panel fit — S00 footprint on DIN rail Mounting position is vertical. Dimensions: 170 mm height, 90 mm width, 97.1 mm depth — the S00 frame size keeps the panel footprint tight for a reversing starter. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the sides, zero forwards or backwards. This matters when laying out multiple starters in a row — the side gap is minimal, but the top and bottom need room for wiring and heat dissipation. ## Motor power ratings across common voltages Power and current vary by supply voltage: 0.1 hp at 230 V, 550 W at 400 V, 1.6 A at 480 V, 550 W at 500 V, 1.3 A at 600 V, 1100 W at 690 V. Also rated 0.75 hp at both 460/480 V and 575/600 V — useful for North American motor nameplates. The magnetic short-circuit trip handles fault clearing without relying on upstream fuses for low-level faults. ## Environmental limits and wiring Operates from -20 °C to +60 °C, stores from -50 °C to +80 °C, and transports from -55 °C to +80 °C. Pollution degree 3 — suitable for industrial environments with conductive dust or humidity. AWG equivalents: 2×(20-16), 2×(18-14), or 2×12 for the contactor side. The reversing starter ships as a single orderable unit — no separate overload or contactor to source.","metaTitle":"Siemens 3RA2215-1AA15-2BB4 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2215-1AA15-2BB4 SIRIUS non-fused reversing motor starter, size S00, 24 V DC coil, thermal Class 10 overload, 550 W at 400 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":"3RA2215-1AA15-2BB4","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 1.1-1.6A 24V DC screw connection For screw mounting Or 35 mm rail-mounting Type of coordination 2 IQ = 150 KA Also full fills 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":"2","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S00","at 230 V rated value":"0.1 hp","at 400 V rated value":"550 W","at 480 V rated value":"1.6 A","at 500 V rated value":"550 W","at 600 V rated value":"1.3 A","at 690 V rated value":"1 100 W","Design Of The Product":"reversing starter","at 460/480 V rated value":"0.75 hp","at 575/600 V rated value":"0.75 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":"3RV2011-1AA15","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","at 500 V according to IEC 60947-4-1 rated value":"100 000 A","at 690 V according to IEC 60947-4-1 rated value":"100 000 A","operational current at AC-3 at 400 V rated value":"1.5 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":"20.8 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":"1.1 ... 1.6 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":"$102.87","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/509ccf2d36baffeefb32a1a6318bc2e1.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=374332&mlfb=3RA2215-1AA15-2BB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2215-1AA15-2BB4","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/3RA2215-1AA15-2BB4 when reusing this data.
