It provides a mechanical rejection feature that prevents the installation of non-Class R fuses, ensuring only the correct fuse type is used in the circuit. This kit is an OEM-style accessory that installs directly into compatible safety switch enclosures. Licensed electricians and electrical contractors install this component during new installations or service calls where fuse type enforcement is required by code or system design. The kit ships as a single unit and is UL and CSA listed, confirming it meets North American electrical safety standards.\u003c\/p\u003e\n\u003cp\u003eThis fuse rejection kit is intended for use in both residential and commercial electrical panel and safety switch applications. It is specifically engineered for Class 3110 safety switches in NEMA 1 and NEMA 3R enclosures. Typical installation scenarios include service entrance equipment, motor disconnect applications, and branch circuit protection setups where Class R fuse rejection is required. The kit is compatible with the following Square D heavy duty safety switch models: H323DS, H324A, H324AWK, H324DS, H324N, and H324NRB.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass R fuse rejection design prevents incorrect fuse installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with NEMA 1 and NEMA 3R enclosure types\u003c\/li\u003e\n  \u003cli\u003eUL and CSA listed for North American electrical installations\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant construction\u003c\/li\u003e\n  \u003cli\u003eSold as a single kit (quantity: 1 each)\u003c\/li\u003e\n  \u003cli\u003eCountry of origin: United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Class 3110 NEMA 1 and NEMA 3R heavy duty safety switches, specifically models H323DS, H324A, H324AWK, H324DS, H324N, and H324NRB.

De-energize and lock out the safety switch before beginning any work on the enclosure or fuse block. Verify the rejection kit is fully seated and secured before restoring power. Do not bypass or modify the rejection feature, as doing so defeats the purpose of Class R fuse type enforcement.\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\u003eApprovals\u003c\/strong\u003e: UL, CSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type Compatibility\u003c\/strong\u003e: NEMA 1, NEMA 3R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.28 inches (L) x 6.93 inches (W) x 22.29 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 1 each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGTIN\u003c\/strong\u003e: 00785901011088\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: SCHNEIDER ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HRK1020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51283945521458,"sku":"HRK1020","price":56.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279196.jpg?v=1781063863","url":"https:\/\/voomisupply.com\/products\/schneider-electric-hrk1020-class-r-fuse-rejection-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
