It provides overcurrent protection in HVAC and commercial electrical systems where both motor-start inrush tolerance and sustained overload protection are required. The dual-element design separates the overload-sensing element from the short-circuit-sensing element, allowing the fuse to ride through normal motor starting currents without nuisance opening while still clearing faults quickly. Licensed electricians and HVAC technicians install this fuse in disconnect boxes and fused load centers serving compressors, air handlers, and other motor-driven equipment.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and commercial HVAC applications where RK5-class fusing is specified. Typical installations include fusible disconnect switches serving condensing units, rooftop units, and other motor loads that draw significant inrush current at startup. The 250-volt rating covers standard single-phase and three-phase branch circuits within that voltage class. Verify the fuse class, amperage, voltage rating, and holder compatibility before installation to ensure the fuse meets the system protection requirements and applicable electrical code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRK5 class dual-element design tolerates motor-start inrush while protecting against sustained overloads and short circuits\u003c\/li\u003e\n  \u003cli\u003e100-amp amperage rating for high-capacity branch circuit and disconnect applications\u003c\/li\u003e\n  \u003cli\u003e250-volt rating covers standard single-phase and three-phase circuits within that class\u003c\/li\u003e\n  \u003cli\u003eTime-delay characteristic reduces nuisance trips on motor-driven HVAC equipment\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement form factor for existing RK5-class fuse holders and disconnect switches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for RK5-class fuse holders and fusible disconnects rated for 100-amp, 250-volt service in HVAC and commercial electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and applicable local codes. Always open and lock out the upstream disconnect and verify the circuit is de-energized with a calibrated meter before removing or installing fuses. Confirm the fuse holder is rated for RK5-class fuses and that the ampacity and voltage rating of the fuse match the circuit and equipment nameplate requirements. Never replace a fuse with one of a higher amperage rating than specified by the equipment manufacturer or the overcurrent protection design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Dual Element Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 100 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\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: DIVERSITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7CRNR100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":51344095707442,"sku":"7CRNR100","price":38.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555332.jpg?v=1782029139","url":"https:\/\/voomisupply.com\/products\/diversitech-7crnr100-rk5-dual-element-time-delay-fuse-100a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
