This kit prevents two contactors or starters from being energized simultaneously, a critical safety function in reversing or transfer switching applications. It creates a physical barrier between adjacent starters, ensuring only one can close at a time. Electricians and industrial controls technicians install this hardware when building reversing starter assemblies or automatic transfer panels. The kit measures 10.5 inches long by 0.25 inches wide by 16 inches high and weighs 0.11 pounds.\u003c\/p\u003e\n\u003cp\u003eThis interlock kit is suited for industrial and commercial electrical control panel applications where two Size 3 Siemens starters are mounted side by side. Typical install scenarios include three-phase motor reversing circuits, multi-speed motor control, and source transfer switching. It is a direct mechanical accessory that mounts between paired starter units without requiring additional wiring. Qualified electricians and motor control specialists perform this installation as part of panel assembly or starter replacement work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMechanical interlock prevents simultaneous engagement of two paired Size 3 starters\u003c\/li\u003e\n  \u003cli\u003eDesigned for reversing starter and transfer switching applications\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.11 pounds for easy panel installation\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 10.5 inches by 0.25 inches by 16 inches fits standard enclosure layouts\u003c\/li\u003e\n  \u003cli\u003eNo additional wiring required — purely mechanical interlock action\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Size 3 to Size 3 Siemens motor starter pairings as an OEM-style mechanical interlock accessory.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements and the panel manufacturer guidelines. De-energize and lock out the panel before beginning any starter or accessory installation. The interlock kit mounts mechanically between adjacent starters and must be aligned correctly to ensure proper interlock action before the enclosure is closed and power is restored. Do not force the mechanism into place, as misalignment can compromise the interlock function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Rating\u003c\/strong\u003e: Size 3 to Size 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 10.5 inches x 0.25 inches x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78308708845\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: 49HHP22H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383083434290,"sku":"49HHP22H","price":261.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675152.jpg?v=1782587590","url":"https:\/\/voomisupply.com\/products\/siemens-49hhp22h-interlock-kit-size-3-to-3","provider":"Voomi Supply","version":"1.0","type":"link"}
