This kit allows qualified electricians to convert an existing safety switch in the field without replacing the full enclosure. Class R fuses offer superior current-limiting performance compared to older fuse classes, making this conversion a practical upgrade for panels and disconnect applications in both residential and commercial electrical systems. The kit is intended for installation by licensed electricians familiar with disconnect switch service and NEC compliance requirements.\u003c\/p\u003e\n\u003cp\u003eThis conversion kit is suited for use in light commercial and industrial electrical installations where safety switches require retrofitting to accept Class R fuse configurations. Typical applications include service disconnects, branch circuit protection, and equipment shutoffs. The field conversion approach reduces downtime by allowing the upgrade to be completed on-site during scheduled maintenance or equipment changeover rather than requiring full switch replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEnables field conversion of compatible safety switches to accept Class R fuses\u003c\/li\u003e\n  \u003cli\u003eClass R fuse compatibility provides improved current-limiting protection\u003c\/li\u003e\n  \u003cli\u003eDesigned for on-site installation without full switch enclosure replacement\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential, light commercial, and industrial disconnect applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style field conversion kit for compatible ABB safety switch enclosures requiring Class R fuse capability.

Disconnect and lock out all power to the safety switch before beginning any conversion work. Follow the included ABB installation instructions for proper component placement and torque guidance. Do not energize the switch until the conversion is fully complete and the enclosure is properly closed and secured.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Field Conversion Kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164180527\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: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TRK66A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383959650610,"sku":"TRK66A","price":73.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672512.png?v=1782613231","url":"https:\/\/voomisupply.com\/products\/abb-trk66a-class-r-fuse-field-conversion-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
