The fuse body is constructed from melamine and measures 1.5 inches in overall length with a 10.3 mm diameter, fitting standard fuse holders used across industrial and commercial panels. It carries an interrupting rating of 100 kA at AC, making it suitable for high-fault-current environments. Licensed electricians and control panel technicians install this fuse as part of branch-circuit or equipment-protection assemblies where fast-clearing characteristics are required to protect sensitive downstream components.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in control panels, instrumentation enclosures, and light industrial equipment operating at up to 600 volts AC. Its fast-acting response time makes it appropriate for circuits without high inrush loads, such as resistive loads and low-current signal circuits. The compact cartridge form factor allows direct installation into midget fuse holders commonly found in motor control centers, HVAC control boards, and process control cabinets in both commercial and light industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFast-acting response for immediate overcurrent clearing on resistive and low-inrush circuits\u003c\/li\u003e\n  \u003cli\u003eRated 3.5 amps at 600 volts AC for broad general-purpose circuit protection\u003c\/li\u003e\n  \u003cli\u003e100 kA interrupting rating at AC for use in high-fault-current environments\u003c\/li\u003e\n  \u003cli\u003eMelamine fuse body resists heat and supports reliable arc suppression\u003c\/li\u003e\n  \u003cli\u003eCompact 1.5-inch length and 10.3 mm diameter fits standard midget fuse holders\u003c\/li\u003e\n  \u003cli\u003eUL Listed, CSA Certified, CE Marked, and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard midget cartridge fuse holders accommodating a 10.3 mm diameter, 1.5-inch length form factor, as commonly specified in general-purpose control circuit and instrumentation panel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NEC requirements for overcurrent protection. De-energize and lock out the circuit before removing or inserting the fuse. Verify the fuse holder is rated for the circuit voltage and that the replacement fuse amperage matches the circuit protection requirements exactly. Do not substitute a fuse of a higher amperage rating to restore a tripped circuit without first identifying and correcting the fault condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 3.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 100 kA at AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Body Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 10.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Melamine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed 248-14 Guide JDYX File E19180; CSA C22.2 No.248.14 Class 1422-01 File 53787; CE Certified; RoHS Compliant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\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: KTK-3-1\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51689401352498,"sku":"KTK-3-1\/2","price":161.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3025ea5eb65f03cf44c9140d2fa4cf71.jpg?v=1788258881","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-ktk-3-1-2-fast-acting-fuse-3-5a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
