Time-delay (TD) fuses are designed to withstand brief inrush currents during motor starts and transformer energizing without nuisance tripping, while still providing reliable overcurrent protection under sustained fault conditions. Sold in a pack of 10, this fuse is a standard trade-quantity format suited for electricians stocking service vans or maintaining panel and equipment inventories. The RK5 classification ensures it meets established rejection standards for current-limiting performance.\u003c\/p\u003e\u003cp\u003eThis fuse is used in residential and light commercial electrical systems, including HVAC equipment branch circuits, motor control panels, and distribution boards where 250-volt, 3-amp overcurrent protection is required. The time-delay characteristic makes it appropriate for inductive loads such as small motors and transformer primaries. Electricians and HVAC technicians commonly specify RK5-class fuses for equipment protection in fused disconnects and fuse blocks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-amp, 250-volt rating for branch circuit and equipment protection\u003c\/li\u003e\n\u003cli\u003eRK5 class current-limiting fuse with rejection design\u003c\/li\u003e\n\u003cli\u003eTime-delay characteristic handles motor inrush without nuisance tripping\u003c\/li\u003e\n\u003cli\u003ePack of 10 for efficient stocking and service use\u003c\/li\u003e\n\u003cli\u003eCompact form factor suitable for standard fuse holders and fused disconnects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for RK5-class time-delay fuses in 250-volt-rated fuse holders and fused disconnect switches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before replacing any fuse. Verify the replacement fuse matches the existing amperage, voltage, and fuse class before installation. Do not substitute a fuse of a higher ampere rating to restore power to a faulted circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 3 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\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 (TD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78200174768\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TR3R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383413604658,"sku":"TR3R","price":37.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675442.jpg?v=1782595815","url":"https:\/\/voomisupply.com\/products\/merit-brass-tr3r-time-delay-fuse-3a-250v-rk5-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
