At 150 mm deep, 55 mm wide and 274 mm tall, it occupies the full S2 frame envelope; the 50 mm upward clearance and 32 mm forward clearance are the minimum free air space around the enclosure for cable entry and heat dissipation. Mounting position is vertical or horizontal, so the starter fits in a shallow enclosure laid on its side as long as the ambient stays within -20 to +60 °C during operation. ## Motor switching capacity and overload protection The supplied contactor is 3RT2037-1NB30 and the link module is 3RA2931-1AA00 — if either component fails in the field, these are the order codes for the replacement parts, not the whole starter assembly. ## Sourcing and compliance The substance prohibitance date of 03/01/2017 confirms RoHS compliance per the EU directive; the operating temperature range of -20 to +60 °C and storage range of -50 to +80 °C cover most industrial enclosure environments.","metaTitle":"Siemens 3RA2150-4JA37-0NB3 SIRIUS Motor Starter, 65 A AC-3","metaDescription":"Siemens 3RA2150-4JA37-0NB3 SIRIUS direct-on-line starter, 65 A at 400 V AC-3, Class 10 trip, screw & snap-on dual DIN-rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"150 mm","Width":"55 mm","title":"3RA2150-4JA37-0NB3","Height":"274 mm","Upwards":"50 mm","Forwards":"32 mm","at 50 Hz":"2 VA","at 60 Hz":"2 VA","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"10 mm","Rated Value":"20 ... 33 V","description":"Load feeder fuseless, Direct-on-line starting 400 V AC, Size S2 54...65 A 20... 33 V AC/DC screw terminal for installation on standard mounting rail (also fulfills type of coordination 1) Type of coordination 2, Iq = 150 kA 1 NO+1 NC (contactor) with circuit (integrated)","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 to two 35 mm DIN rails","Mounting Position":"vertical, horizontal","PROFIsafe protocol":"No","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Product Designation":"Direct (on-line) starter","Size Of Load Feeder":"S2","PROFINET IO protocol":"No","at 400 V rated value":"30 000 kW","at 480 V rated value":"65 A","at 50 Hz rated value":"20 ... 33 V","at 60 Hz rated value":"20 ... 33 V","at 600 V rated value":"52 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"screw-type terminals","Temperature Compensation":"-20 ... +60 °C","Of The Supplied Contactor":"3RT2037-1NB30","Of The Supplied Link Module":"3RA2931-1AA00","Size Of The Circuit-Breaker":"S2","at AC-3 rated value maximum":"690 V","at AC-3 at 400 V rated value":"65 A","at AC-3e rated value maximum":"690 V","Substance Prohibitance (Date)":"03/01/2017","at AC-3e at 400 V rated value":"65 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":"3RV2032-4JA10","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":"2 W","holding power of magnet coil at DC":"1 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"12.5 W","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","apparent holding power of magnet coil at AC":"2 VA","protocol is supported AS-Interface protocol":"No","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":"AC/DC","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","Inductive Power Factor With The Holding Power Of The Coil":"1","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"845 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":"54 ... 65 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e5bcd91c4e31d4cfdfeaec025b74f81a.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=396478&mlfb=3RA2150-4JA37-0NB3"},"ai":{"faq":[{"question":"What compliance documentation does Siemens provide for 3RA2150-4JA37-0NB3?","answer":"The substance prohibitance date of 03/01/2017 confirms RoHS compliance.
