At 5 inches overall length and 20.6 mm diameter, this two-element fuse provides reliable time delay performance that allows motors and other inductive loads to tolerate temporary inrush current without nuisance tripping. It carries interrupting ratings of 100 kA at DC and 300 kA at AC (RMS), making it suitable for high-fault-current environments. Licensed electricians and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fuse is intended for use in fuse holders configured for RK1 class cartridge fuses. Typical applications include motor branch circuits, control panels, and industrial machinery where time delay characteristics are required to ride through startup inrush. The RK1 class designation indicates a current-limiting fuse with a high interrupting rating, appropriate for both commercial and light industrial installations where fault current levels demand robust overcurrent protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRK1 class current-limiting fuse with time delay for motor and inductive load protection\u003c\/li\u003e\n  \u003cli\u003e5 amp rating with 300 kA interrupting rating at AC (RMS) and 100 kA at DC\u003c\/li\u003e\n  \u003cli\u003eTwo-element construction provides accurate time delay without sacrificing fault response\u003c\/li\u003e\n  \u003cli\u003eNon-indicating design in a standard cartridge body for fuse holder mounting\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA Certified (CSA C22.2 No. 248.12), and UL Listed (Guide JDDZ File E4273)\u003c\/li\u003e\n  \u003cli\u003e5 inches overall length and 20.6 mm diameter for compatibility with standard RK1 fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fuse holders accepting RK1 class cartridge fuses.

De-energize and lockout\/tagout the circuit before removing or installing any fuse. Confirm the fuse holder is rated for RK1 class fuses and that the system voltage and available fault current fall within the fuse ratings. Never substitute a fuse of a different class, higher amperage, or lower interrupting rating for this fuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 5 amps\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\u003eInterrupting Rating (AC RMS)\u003c\/strong\u003e: 300 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (DC)\u003c\/strong\u003e: 100 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 20.6 mm\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: Non-Indicating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE Certified; CSA C22.2 No. 248.12 Class 1422-02 File 53787; UL Listed Guide JDDZ File E4273\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: LPS-RK-5SP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51702418997554,"sku":"LPS-RK-5SP","price":747.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9ff8e6a22ac2002881496f2bc85ce81.jpg?v=1788410726","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-lps-rk-5sp-time-delay-fuse-5a-rk1","provider":"Voomi Supply","version":"1.0","type":"link"}
