It provides overcurrent protection with an interrupting rating of 100 kA at DC and 200 kA at AC, making it suitable for demanding electrical distribution applications. The body measures 7-7\/8 inches overall length and 1-5\/16 inches in diameter, constructed from fiberglass and polyester materials. Licensed electricians install this fuse in branch circuits, motor circuits, and feeder panels where time delay characteristics are required to ride through normal inrush currents without nuisance tripping.\u003c\/p\u003e\n\u003cp\u003eThis fuse is used in commercial and industrial electrical systems where RK5-class protection is specified. Common applications include motor branch circuit protection, transformer primary protection, and general-purpose feeder circuits. The time delay feature allows motors and other inductive loads to start without opening the fuse during the brief high-inrush startup period, while still providing fast response to sustained fault conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eRK5 classification for branch circuit and motor circuit overcurrent protection\u003c\/li\u003e\n \u003cli\u003e75 amp continuous current rating\u003c\/li\u003e\n \u003cli\u003e200 kA AC interrupting rating for high-fault-current environments\u003c\/li\u003e\n \u003cli\u003e100 kA DC interrupting rating\u003c\/li\u003e\n \u003cli\u003eTime delay design accommodates motor inrush without nuisance tripping\u003c\/li\u003e\n \u003cli\u003eFiberglass and polyester body construction for durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for RK5-class cylindrical fuses in standard fuse holders and fusible disconnects accepting 7-7\/8 inch by 1-5\/16 inch cartridge fuses rated 75 amps.\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. De-energize and lock out the circuit before removing or installing any fuse. Use properly rated fuse pullers rated for the voltage and ampere class involved. Verify the fuse holder is rated for RK5-class fuses and that the circuit voltage does not exceed the fuse voltage rating before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 75 amps\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (AC)\u003c\/strong\u003e: 200 kA\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (DC)\u003c\/strong\u003e: 100 kA\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 7-7\/8 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Fiberglass and Polyester\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time Delay Cylindrical\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: FERRAZ SHAWMUT\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TRS75R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERRAZ SHAWMUT","offers":[{"title":"Default Title","offer_id":68296047591730,"sku":"TRS75R","price":410.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/016cebd4b581ebef7dcd9999ab59bb05.jpg?v=1793698666","url":"https:\/\/voomisupply.com\/products\/ferraz-shawmut-trs75r-time-delay-fuse-rk5-75a","provider":"Voomi Supply","version":"1.0","type":"link"}
