This accessory provides a mechanical and electrical bridge between adjacent MSP units, allowing them to be grouped into a compact, bus-connected assembly on a common mounting rail. Electricians and industrial control panel builders use this link when building out motor control centers or multi-motor starter banks. The part ships as a single unit and weighs 0.082 pounds, with a package footprint of 4.173 inches by 2.480 inches by 1.850 inches.\u003c\/p\u003e\u003cp\u003eThis connecting link is intended for use in industrial electrical control panels where multiple MSP units must be ganged together. Typical applications include motor control centers, machine tool control cabinets, and panel assemblies where space-saving side-by-side MSP mounting is required. The link supports clean, organized wiring layouts and reduces the need for discrete jumper wiring between adjacent starters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMechanically connects adjacent MSP units for grouped assembly mounting\u003c\/li\u003e\n\u003cli\u003eEliminates discrete jumper wiring between side-by-side motor starter protectors\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for dense control panel installations\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.082 pounds for easy handling during panel build\u003c\/li\u003e\n\u003cli\u003eSold as a single unit per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style accessory connecting link for use with compatible SIEMENS manual starter protector (MSP) units in grouped assembly configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements and the panel manufacturer guidelines. De-energize and lock out the control panel before installing or removing any MSP accessories. Verify that all MSP units being linked are correctly seated on the DIN rail before securing the connecting link. Do not force the link into position, as misalignment can damage the MSP contact interfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.082 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.480 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.850 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455489906\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3RA1921-1AA00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383566467378,"sku":"3RA1921-1AA00","price":52.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678816.jpg?v=1782600744","url":"https:\/\/voomisupply.com\/products\/siemens-3ra1921-1aa00-msp-connecting-link","provider":"Voomi Supply","version":"1.0","type":"link"}
