Sold under the Tri-Onic TRS-R product line, it features a blade-style terminal configuration and is engineered for overcurrent protection in demanding electrical distribution systems. The time-delay characteristic allows the fuse to ride through harmless motor starting currents and transformer inrush currents without nuisance opening, while still providing fast, reliable response to damaging fault conditions. Licensed electricians and electrical contractors are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThe trs450r is suited for service entrance equipment, feeders, branch circuits, motor circuits, and transformer protection applications. Its current-limiting action reduces let-through energy during high-magnitude fault events, helping protect downstream equipment and wiring. Residential, commercial, and light industrial electrical systems that require Class RK5 performance benefit from this fuse type. It is appropriate wherever time-delay overcurrent protection at 600 volts and 450 amps is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK5 current-limiting time-delay design for motor and transformer circuit protection\u003c\/li\u003e\n  \u003cli\u003e450 amp continuous current rating\u003c\/li\u003e\n  \u003cli\u003e600 volt AC and 600 volt DC rating for broad application flexibility\u003c\/li\u003e\n  \u003cli\u003eBlade-style terminals for standard fuse holder and disconnect compatibility\u003c\/li\u003e\n  \u003cli\u003eTime-delay characteristic handles motor starting inrush without nuisance opening\u003c\/li\u003e\n  \u003cli\u003eSuitable for service entrance, feeder, and branch-circuit overcurrent protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class RK5 replacement fuse for use in blade-type fuse holders and fusible disconnects rated for 450 amps at 600 volts AC or DC.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lock out the circuit and verify absence of voltage with a meter before removing or installing any fuse. Use properly rated fuse pullers and insulated tools. Never replace a fuse with a higher ampere rating than specified for the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 450A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating (AC)\u003c\/strong\u003e: 600 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating (DC)\u003c\/strong\u003e: 600 volts DC\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, Current-Limiting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Style\u003c\/strong\u003e: Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Series\u003c\/strong\u003e: Tri-Onic TRS-R\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: trs450r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51268872896818,"sku":"TRS450R","price":896.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913236.webp?v=1780708316","url":"https:\/\/voomisupply.com\/products\/mersen-trs450r-class-rk5-time-delay-fuse-450a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
