It features a pin indicator and a two-element design that tolerates harmless inrush currents while still protecting against sustained overloads and short circuits. The fuse body is green and mounts in a standard fuse holder. With an interrupting rating of 35 amps at 250 volts and an overall length of 1.5 inches, this fuse is sized for precision low-current protection in control circuits, instrumentation panels, and light commercial equipment. Installation is handled by licensed electricians and qualified control technicians.\u003c\/p\u003e\u003cp\u003eThe FNA-3\/10 is suited for use in fuse holders in low-voltage control panels, HVAC equipment control circuits, instrumentation enclosures, and similar applications where time-delay protection is required for small inductive or motor loads. The pin indicator provides a visible signal when the fuse has opened, reducing diagnostic time during service calls. Its compact cartridge form fits standard holders designed for this fuse series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime-delay action tolerates normal inrush current without nuisance opening\u003c\/li\u003e\n\u003cli\u003ePin indicator provides visible blown-fuse indication for fast troubleshooting\u003c\/li\u003e\n\u003cli\u003eTwo-element construction for reliable overload and short-circuit protection\u003c\/li\u003e\n\u003cli\u003eGreen body color aids quick visual identification in multi-fuse panels\u003c\/li\u003e\n\u003cli\u003eCE Certified, CSA Certified, and UL Listed for broad code compliance\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch cartridge fits standard fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in fuse holders that accept standard 1.5-inch cartridge fuses of this current rating.

De-energize and lock out the circuit before removing or installing the fuse. Use an appropriately rated fuse puller when removing cartridge fuses from live or recently energized holders. Verify that the replacement fuse amperage and voltage ratings match the circuit protection requirements before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 0.3 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 35 amps at 250 volts; 10 kA at 125 volts\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\u003eNumber of Elements\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Pin Indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE Certified; CSA Class 1422-01 File 53787; UL Listed Guide JDYX File E19180\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: FNA-3\/10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51717377294642,"sku":"FNA-3\/10","price":45.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/deeb680dabc82c6ad7c7a03a473f1919_408d1c40-d078-444c-9192-2cfc11ca46b9.jpg?v=1788539396","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-fna-3-10-cartridge-time-delay-fuse-0-3a","provider":"Voomi Supply","version":"1.0","type":"link"}
