Time-delay fuses in the RK5 class are designed to withstand harmless inrush currents — such as motor starting surges — while still opening quickly under sustained overload or short-circuit conditions. This fuse is packaged in a count of 10 per pack. Licensed electricians and industrial maintenance technicians install Class RK5 fuses in fused disconnect switches, control panels, and branch-circuit protection applications where precise overcurrent coordination is required.\u003c\/p\u003e\n\u003cp\u003eThe TR1-8\/10R is suited for low-voltage control circuits, small motor branch circuits, and equipment protection in both light commercial and residential electrical systems where a 50-volt, Class RK5 fuse is specified. The 10-per-pack format supports panel stocking and service van inventory for electrical contractors and industrial maintenance operations. The compact physical size makes it appropriate for standard fuse holders that accept RK5 cartridge fuses in this ampere rating range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK5 time-delay design tolerates motor inrush without nuisance opening\u003c\/li\u003e\n  \u003cli\u003e1-8\/10A (1.8A) rating for precision overcurrent protection in low-amperage circuits\u003c\/li\u003e\n  \u003cli\u003e50-volt AC\/DC rating suitable for low-voltage control and equipment circuits\u003c\/li\u003e\n  \u003cli\u003ePackaged 10 per pack for efficient field and panel-room stocking\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 3.0 x 2.06 x 1.19 inches per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard Class RK5 fuse holders and fused disconnect switches that accept a 1-8\/10A, 50V cartridge fuse. Consult the equipment manufacturer's fuse specification before installation to confirm class and rating requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements for overcurrent protection devices. Always de-energize and lock out\/tag out the circuit before replacing fuses. Verify that the replacement fuse class, voltage rating, and ampere rating match the equipment manufacturer's specification exactly — substituting a different class or higher ampere rating can defeat the overcurrent protection coordination of the system. Use an approved fuse puller when removing or installing cartridge fuses.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 1-8\/10A (1.8A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 50 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\u003ePack Quantity\u003c\/strong\u003e: 10 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 3.0 x 2.06 x 1.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.530 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174763\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: Mersen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TR1-8\/10R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383482614066,"sku":"TR1-8\/10R","price":46.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675433.jpg?v=1782598031","url":"https:\/\/voomisupply.com\/products\/mersen-tr1-8-10r-rk5-time-delay-fuse-1-8-10a-50v","provider":"Voomi Supply","version":"1.0","type":"link"}
