This model uses blade connections at both ends and is non-indicating, so there is no built-in fuse-status indicator. Physical fit also deserves attention: the FRS-R-350 measures 11.63 inches long, 2.59 inches high, and 2.59 inches wide. If you already have FRS-R-350 listed in your equipment documentation or on the fuse being replaced, that's a useful starting point. From there, compare the complete electrical and physical specifications—including fuse class, voltage, interrupt rating, blade configuration, and dimensions—to confirm that the replacement matches the equipment requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e350A Class RK5 rating: Clearly identifies the amperage and fuse class for comparison with equipment specifications.\u003c\/li\u003e\n\u003cli\u003e600 VAC and 300 VDC ratings: Provide defined ratings for both AC and DC applications when equipment requirements match.\u003c\/li\u003e\n\u003cli\u003eDual-element design: Matches the manufacturer's stated configuration for the FRS-R-350.\u003c\/li\u003e\n\u003cli\u003eDefined response specification: Rated at 10 seconds at 500% of rated current.\u003c\/li\u003e\n\u003cli\u003eBlade-end-to-blade-end connection: Makes it easy to verify the connection style against the existing fuse and equipment.\u003c\/li\u003e\n\u003cli\u003eNon-indicating construction: Designed without a built-in fuse status indicator.\u003c\/li\u003e\n\u003cli\u003eCE Marked: CE marking is included in the supplied manufacturer specifications.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Eaton Bussmann series FRS-R fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e FRS-R-350\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712508520\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e Class RK5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 350 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Voltage Rating:\u003c\/strong\u003e 600 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Voltage Rating:\u003c\/strong\u003e 300 VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupt Rating:\u003c\/strong\u003e 200 kAIC at 600 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupt Rating:\u003c\/strong\u003e 20 kAIC at 300 VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 sec at 500%\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e Dual\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Blade end x blade end\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\/Depth:\u003c\/strong\u003e 11.63 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 2.59 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 2.59 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 0.00052 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe FRS-R-350 is CE-marked according to the supplied manufacturer information.
