Designed for general-purpose overcurrent protection, this fuse provides rapid response to fault conditions, making it well-suited for control circuits, motor control centers, and industrial distribution panels. Electricians and controls technicians install this fuse in fuse holders that accept Class CC rejection-style bodies. Its compact cartridge form measures 1.5 inches in length and 10.3 mm in diameter.\u003c\/p\u003e\n\u003cp\u003eThe KTK-R-4 is used in residential and commercial electrical systems where Class CC fuse holders are specified. Typical applications include branch circuit protection for control transformers, instrumentation panels, and low-amperage feeder circuits. The rejection feature prevents the installation of non-Class CC fuses in Class CC holders, enforcing correct overcurrent protection by design. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFast-acting fuse response for rapid fault clearing on sensitive control circuits\u003c\/li\u003e\n  \u003cli\u003eClass CC rejection body prevents cross-installation of incompatible fuse types\u003c\/li\u003e\n  \u003cli\u003e200 kA AC RMS interrupting rating for high-fault-current environments\u003c\/li\u003e\n  \u003cli\u003e600-volt rating supports a wide range of single-phase and three-phase control applications\u003c\/li\u003e\n  \u003cli\u003eUL Listed 248-4 Class CC, CSA Certified, CE Certified, and RoHS Compliant\u003c\/li\u003e\n  \u003cli\u003eCompact cartridge form fits standard Class CC fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Class CC fuse holders that accept rejection-style cartridge fuses.

De-energize and lock out the circuit before removing or installing any fuse. Use an insulated fuse puller rated for the application voltage when servicing fuses in live-adjacent panels. Verify the replacement fuse amperage and class marking match the original fuse and the circuit overcurrent protection requirements before closing the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 600 volts AC\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\u003eBody Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRejection Setting\u003c\/strong\u003e: Rejecting\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed 248-4 Class CC Guide JDDZ File E4273; CSA C22.2 No. 248.4 File 53787 Class 1422-02; 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-R-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51693773390130,"sku":"KTK-R-4","price":496.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d065555a2774ab41df5860825fe0dd8.jpg?v=1788317197","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-ktk-r-4-class-cc-fast-acting-fuse-4a-600v","provider":"Voomi Supply","version":"1.0","type":"link"}
