It integrates a thermal bimetallic overload relay (Class 10 trip) and a magnetic short-circuit release in one package, so a single unit provides both running overload protection and fault-current interruption up to the rated breaking capacity of the built-in contactor and circuit-breaker combination. The starter snaps onto 60 mm busbar systems using the supplied busbar adapter (8US1251-5DT11), which means it installs directly onto the panel's main power distribution bars without extra DIN-rail brackets — a time-saver in busbar-fed motor control centres. ## Mounting and wiring constraints Mounting position is vertical only, with 50 mm clearance upwards and 20 mm forwards — the backwards clearance is zero, so the back of the unit sits flush against the busbar or panel backplane. Main current circuit connections use spring-loaded terminals (cage-clamp style), which speed wiring compared to screw terminals and hold up better under vibration. ## Environmental limits and operating range Operating temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C — the unit can sit in an unheated warehouse or ship through cold climates without damage. Rated for 50/60 Hz supply, so it works on either 50 Hz or 60 Hz networks without derating.","metaTitle":"Siemens 3RA2115-0BH15-1FB4 SIRIUS Direct Starter","metaDescription":"Siemens 3RA2115-0BH15-1FB4 SIRIUS direct-on-line starter, size S00, 60 kW at 400 V AC-3, Class 10 thermal overload, spring terminals, snaps onto 60 mm busbars.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"45 mm","title":"3RA2115-0BH15-1FB4","Height":"260 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 0.14...0.20 A 24 V DC Spring-type terminal for 60 mm busbar systems (also fulfills type of coordination 1) Type of coordination 2, Iq = 150 kA 1 NO (contactor) with diode (integrated)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"for snapping onto 60 mm busbar systems","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 400 V rated value":"60 kW","at 480 V rated value":"0.2 A","at 600 V rated value":"0.2 A","Design Of The Product":"for 60 mm busbars","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-20 ... +60 °C","Of The Supplied Contactor":"3RT2015-2FB41","Of The Supplied Link Module":"3RA2911-2AA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","at AC-3 at 400 V rated value":"0.2 A","at AC-3e rated value maximum":"690 V","at AC-3e at 400 V rated value":"0.2 A","Design Of The Overload Release":"thermal (bimetallic)","Of The Supplied Busbar Adapter":"8US1251-5DT11","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":"3RV2011-0BA25","degree of protection NEMA rating":"other","For Auxiliary And Control Circuit":"spring-loaded 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 W","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","protocol is supported AS-Interface protocol":"No","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":"2.6 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":"0.14 ... 0.2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/685804382cfbb56fc224d5da957b5535.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=553384&mlfb=3RA2115-0BH15-1FB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2115-0BH15-1FB4","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/3RA2115-0BH15-1FB4 when reusing this data.
