RK1 fuses offer a high degree of current limitation, interrupting fault currents quickly to protect downstream equipment, conductors, and personnel. This fuse is installed by licensed electricians during panel builds, distribution upgrades, or equipment service calls where Class RK1 protection is specified.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in motor branch circuits, feeder circuits, and service-entrance equipment operating at voltages up to 250 volts AC. Class RK1 fuses are commonly specified where tight current-limiting performance is required, including applications involving motors, transformers, and sensitive control equipment. The A2K250R fits standard Class RK fuse holders and fused disconnect switches rated for that ampacity and voltage class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK1 current-limiting design for fast fault interruption\u003c\/li\u003e\n  \u003cli\u003e250-volt AC voltage rating suitable for single-phase and three-phase distribution circuits\u003c\/li\u003e\n  \u003cli\u003e250-amp continuous current rating\u003c\/li\u003e\n  \u003cli\u003eFits standard Class RK fuse holders and disconnect switches\u003c\/li\u003e\n  \u003cli\u003eProvides downstream equipment protection in motor and feeder circuit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement Class RK1 fuse for use in standard 250-volt rated fuse holders and fused disconnect switches requiring a 250-amp RK1 fuse.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) requirements for overcurrent protection devices. Always de-energize and lock out the circuit at the upstream disconnect before removing or installing fuses. Verify the fuse holder or disconnect switch is rated for Class RK1 fuses at the appropriate voltage and ampacity before installation. Do not substitute a higher-ampacity or lower-class fuse in place of the specified RK1 rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 250 amps\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: 78200191533\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A2K250R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383501160754,"sku":"A2K250R","price":1330.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677975.jpg?v=1782598606","url":"https:\/\/voomisupply.com\/products\/merit-brass-a2k250r-250v-rk1-fuse-250-amps","provider":"Voomi Supply","version":"1.0","type":"link"}
