Time delay fuses of this type are designed to handle brief inrush currents without nuisance tripping while still providing reliable overcurrent protection for downstream components. The RK5 class designation indicates a rejection-style fuse body that prevents installation of a lower-rated class fuse in the same holder, adding an additional layer of circuit protection. Licensed electricians and HVAC technicians commonly install fuses of this type when servicing control circuits, motor branch circuits, and equipment disconnect panels.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in residential and light commercial electrical panels, equipment disconnects, and fused load centers where a 250-volt, 1-1\/8-amp time delay overcurrent device is specified. The RK5 class is widely used in HVAC equipment, motor control, and general electrical distribution applications where inrush tolerance is required without sacrificing short-circuit protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/8 amp current rating with time delay characteristic for inrush tolerance\u003c\/li\u003e\n  \u003cli\u003e250-volt voltage rating suitable for single-phase branch circuits\u003c\/li\u003e\n  \u003cli\u003eRK5 rejection-class body prevents substitution with lower-rated fuse classes\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits standard RK5-compatible fuse holders and disconnects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for RK5-class time delay fuses in standard 250-volt fuse holders and disconnect blocks rated for the RK5 fuse class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements for overcurrent protection devices. Always de-energize and lock out the circuit at the disconnect or panel before replacing any fuse. Verify the replacement fuse matches the amperage, voltage, and fuse class specified on the equipment nameplate. Never install a fuse with a higher amperage rating than the circuit is designed for.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 1-1\/8 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: RK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174759\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: TR1-1\/8R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383249535282,"sku":"TR1-1\/8R","price":46.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675435.jpg?v=1782591030","url":"https:\/\/voomisupply.com\/products\/merit-brass-tr1-1-8r-time-delay-fuse-1-1-8a-250v-rk5","provider":"Voomi Supply","version":"1.0","type":"link"}
