RK1 fuses provide a high level of overcurrent protection with a dual-element, time-delay design that tolerates temporary motor inrush current while still responding quickly to sustained overloads and short-circuit faults. This fuse is used in branch-circuit and feeder protection applications across residential, commercial, and light industrial electrical systems. Licensed electricians and HVAC technicians install this type of fuse in disconnect boxes, motor controllers, and load centers where RK1-class protection is specified.\u003c\/p\u003e\u003cp\u003eThe A2K6R is suited for motor load circuits, HVAC equipment disconnects, and control panel installations where Class RK1 rejection fuses are required by design or code. The 250-volt, 6-amp rating covers a wide range of single-phase motor branch circuits and small-load feeders. It fits standard RK1-rejection fuse holders that prevent insertion of lower-rated fuse classes, ensuring the integrity of the protection scheme.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass RK1 rejection design prevents substitution of lower-performance fuse classes\u003c\/li\u003e\n\u003cli\u003eTime-delay element handles motor inrush current without nuisance opening\u003c\/li\u003e\n\u003cli\u003eRated 6 amps at 250 volts for branch-circuit protection\u003c\/li\u003e\n\u003cli\u003eDual-element construction provides both overload and short-circuit protection\u003c\/li\u003e\n\u003cli\u003eCompatible with standard RK1-rejection fuse holders and disconnect switches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for Class RK1 fuse applications in standard 250-volt rejection-style fuse holders and fusible disconnects.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC Article 240 requirements for branch-circuit overcurrent protection. Always de-energize and lock out the circuit before removing or installing fuses. Verify the fuse holder accepts Class RK1 rejection ferrules before installation. Do not substitute a lower-class fuse in an RK1-rated holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 6 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200191503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERSEN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A2K6R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51383504437554,"sku":"A2K6R","price":76.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677984.jpg?v=1782598719","url":"https:\/\/voomisupply.com\/products\/mersen-a2k6r-rk1-time-delay-fuse-6a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
