The time-delay characteristic allows the fuse to carry temporary inrush currents from motors and transformers without nuisance opening, while still responding quickly to sustained faults. Rated at 500 amps and 600 volts, this fuse fits standard Class RK5 fuseholders and panelboards. Installation is typically performed by a licensed electrician working within NEC-compliant distribution equipment.\u003c\/p\u003e\n\u003cp\u003eClass RK5 time-delay fuses are used in motor branch circuits, feeder circuits, and industrial control panels where inrush current tolerance is required. This fuse is suitable for both single-phase and three-phase applications in residential service entrances, commercial panels, and light industrial settings. The 600-volt rating accommodates the full range of standard North American distribution voltages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e500-amp continuous current rating for high-capacity branch and feeder circuits\u003c\/li\u003e\n  \u003cli\u003e600-volt rating covers standard North American single-phase and three-phase distribution\u003c\/li\u003e\n  \u003cli\u003eClass RK5 form factor fits listed Class RK5 and Class H fuseholders\u003c\/li\u003e\n  \u003cli\u003eTime-delay design tolerates motor and transformer inrush without nuisance opening\u003c\/li\u003e\n  \u003cli\u003eProvides downstream short-circuit and overload protection per NEC requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 time-delay fuses in listed 500-amp, 600-volt fuseholders and fusible disconnect switches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician. De-energize and lock out the circuit at the upstream disconnect before handling or replacing fuses. Verify the fuseholder is rated for Class RK5 fuses at 600 volts and 500 amps before installation. Follow NEC Article 240 and local electrical code requirements for overcurrent protection and fuseholder compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 500 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\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: 78200174929\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: TRS500R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51383599956274,"sku":"TRS500R","price":896.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675511.jpg?v=1782601766","url":"https:\/\/voomisupply.com\/products\/merit-brass-trs500r-time-delay-fuse-500a-600v-rk5","provider":"Voomi Supply","version":"1.0","type":"link"}
