Time-delay fuses in the RK5 class are designed to withstand short-duration inrush currents common in motor and transformer circuits without nuisance tripping, while still opening quickly on sustained overloads or short-circuit faults. This fuse suits commercial and industrial electrical panels, HVAC equipment, and control circuits where reliable overcurrent protection is required. Licensed electricians and HVAC technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe TRS4R is suited for use in motor branch circuits, HVAC compressor and blower circuits, control panels, and general-purpose distribution equipment operating at up to 600 volts AC. The RK5 current-limiting rating makes it appropriate for systems where downstream equipment requires a degree of short-circuit current limitation. Sold in a 10-count pack, it is a practical stock item for service vans and panel shops handling recurring fuse replacement work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-amp rating with time-delay action accommodates motor inrush without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003e600-volt AC rating covers standard commercial and industrial distribution voltages\u003c\/li\u003e\n  \u003cli\u003eClass RK5 current-limiting design provides downstream component protection\u003c\/li\u003e\n  \u003cli\u003e10-pack quantity supports bulk stocking for service or panel work\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits standard RK5-class fuseholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 fuseholders in residential, commercial, and light industrial electrical and HVAC applications rated up to 600 volts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician or licensed HVAC technician in accordance with NFPA 70 (NEC) requirements for overcurrent protection. Always de-energize and lock out the circuit at the disconnect before replacing any fuse. Verify the fuseholder is rated for Class RK5 cartridge fuses before installing. Never substitute a fuse with a higher ampere rating than the circuit or equipment requires.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 4 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5 Time-Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 5.12 inches x 4.12 inches x 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174871\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: TRS4R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383618273586,"sku":"TRS4R","price":59.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675525.jpg?v=1782602342","url":"https:\/\/voomisupply.com\/products\/merit-brass-trs4r-4a-600v-rk5-time-delay-fuse-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
