By ramping voltage up gradually at startup, it reduces inrush current and mechanical stress on the motor and driven equipment. This type of device is installed in motor control centers, control panels, and standalone enclosures across industrial, commercial HVAC, and pump applications. The unit measures 6.654 x 2.697 x 7.677 inches and weighs approximately 2.866 pounds, making it a compact option for panel integration. Licensed electricians and industrial controls technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 3RW40371BB04 is suited for applications where full-across-the-line starting would cause excessive mechanical shock or electrical demand spikes. Common use cases include conveyor drives, compressor motors, pump systems, and fan arrays in commercial and light industrial settings. It is intended for three-phase motor load control and fits into standard DIN-rail or panel-mount configurations typical of motor control enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSoft start and soft stop function reduces motor inrush current and mechanical wear\u003c\/li\u003e\n  \u003cli\u003eSolid-state design with no moving contact parts for long service life\u003c\/li\u003e\n  \u003cli\u003eCompact footprint at 6.654 x 2.697 x 7.677 inches supports space-constrained panel builds\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2.866 pounds for easier panel integration and mounting\u003c\/li\u003e\n  \u003cli\u003eSuitable for three-phase AC motor loads in commercial and industrial control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style soft starter for three-phase AC motor control applications in commercial and industrial motor control enclosures and panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out all power sources before handling or wiring the soft starter. Verify that the panel supply voltage, motor full-load amperage, and control wiring match the unit specifications before energizing. Do not bypass the soft starter or connect it to single-phase loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.654 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.697 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.677 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.866 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 04089278313\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3RW40371BB04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383210148146,"sku":"3RW40371BB04","price":3570.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677250.jpg?v=1782589774","url":"https:\/\/voomisupply.com\/products\/siemens-3rw40371bb04-soft-starter-motor-control","provider":"Voomi Supply","version":"1.0","type":"link"}
