It features a rejection-style body that prevents substitution with non-CC-class fuses, ensuring code-compliant installations. The fuse measures 1.5 inches in overall length and 10.3 mm in diameter, and mounts in a standard CC fuse holder. Electricians and controls technicians install this fuse in motor control panels, HVAC control circuits, and similar low-current industrial or commercial applications where time-delay characteristics are required to ride through inrush current without nuisance opening.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and light commercial control panels, HVAC equipment control boards, and motor control centers where CC-class fusing is specified. The time delay rating allows the fuse to tolerate brief startup surges while still providing reliable protection against sustained overloads and short circuits. Its cartridge form factor and rejection feature make it a standard choice wherever the circuit design calls for a Class CC time delay fuse in a holder-mounted configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCC-class rejection body prevents installation of non-CC fuses in CC fuse holders\u003c\/li\u003e\n  \u003cli\u003eTime delay rating accommodates motor inrush and transformer energization without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003e3.5-amp rating suitable for low-current control and branch circuits\u003c\/li\u003e\n  \u003cli\u003eCompact cartridge form: 1.5 inches long, 10.3 mm diameter\u003c\/li\u003e\n  \u003cli\u003e200 kA interrupting rating at AC RMS for high fault-current environments\u003c\/li\u003e\n  \u003cli\u003eUL Listed 248-4 Class CC, CSA Class CC certified, CE certified, and RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CC-class fuse holders.

Always de-energize and lockout\/tagout the circuit before replacing or installing fuses. Verify the fuse holder is rated for CC-class cartridge fuses before installation. Do not substitute a non-time-delay or non-CC-class fuse in applications where a time delay or rejection feature is required by the circuit design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 3.5 A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: CC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Body Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 200 kA at AC RMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 10.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRejection Setting\u003c\/strong\u003e: Rejecting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed 248-4 Class CC (Guide JDDZ File E4273), CSA Class CC (File 53787-HRC-MISC), CE Certified, RoHS Compliant\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: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FNQ-R-3-1\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51699642171698,"sku":"FNQ-R-3-1\/2","price":602.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3613dd54d7e5918813f1a6d28b0d8b27.jpg?v=1788378596","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-fnq-r-3-1-2-3-5a-cc-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
