The cartridge body measures 10.3 mm in diameter and 1.5 inches in overall length. Designed for general-purpose overcurrent protection, this fuse is built to the rejection-style CC class standard, which prevents substitution with lower-rated fuse classes. Electricians and control panel technicians install this type of fuse in industrial control circuits, motor branch circuits, and supplementary protection applications where fast-acting response is required to protect sensitive downstream components.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for use in CC-class fuse holders and fuse blocks in both commercial and light industrial electrical systems. Its fast-acting time-current characteristic makes it appropriate for resistive loads and circuits where inrush current is not a concern. The rejection feature ensures the fuse holder accepts only CC-class fuses, maintaining system integrity and preventing field substitutions with non-compliant alternatives. Typical installation environments include control panels, machine tool circuits, and branch circuit protection assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass CC rejection-style body prevents substitution with lower-rated fuse classes\u003c\/li\u003e\n\u003cli\u003eFast-acting response for quick overcurrent protection on resistive and low-inrush circuits\u003c\/li\u003e\n\u003cli\u003e200 kA interrupting capacity at AC RMS for high fault-current environments\u003c\/li\u003e\n\u003cli\u003eCompact cartridge form factor: 10.3 mm diameter, 1.5 inches overall length\u003c\/li\u003e\n\u003cli\u003eMounts in standard CC-class fuse holders and fuse blocks\u003c\/li\u003e\n\u003cli\u003eCE Certified, CSA Certified, UL Listed, and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CC-class fuse holders and rejection-style fuse blocks rated for 600-volt, fast-acting cartridge fuses.

De-energize and lock out the circuit before removing or inserting the fuse. Use a properly rated fuse puller when handling cartridge fuses to avoid contact with energized parts. Verify the fuse holder is rated for Class CC fuses and the circuit voltage and amperage do not exceed the fuse rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: CC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 0.25 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 200 kA at AC RMS\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 (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: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE Certified; CSA C22.2 No. 248.4 File 53787 Class 1422-02 Certified; RoHS Compliant; UL Listed 248-4 Class CC Guide JDDZ File E4273\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39121605\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: KTK-R-1\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51695204696370,"sku":"KTK-R-1\/4","price":230.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01691c28c51015ff67b83f2601b27792.jpg?v=1788332515","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-ktk-r-1-4-cc-fuse-0-25a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
