It measures 7-7\/8 inches overall length and features a dual-element design that provides both overload and short-circuit protection in a single body. The indicating function gives technicians a visible status signal when the fuse has opened, speeding up diagnostics without requiring additional test equipment. Interrupting capacity is rated at 100 kA DC and 300 kA AC (RMS), making it suitable for demanding industrial and commercial electrical applications. Licensed electricians and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fuse is used in industrial control panels, motor branch circuits, HVAC equipment disconnects, and other applications requiring a Class RK1 time delay fuse with bolt-on mounting. The time delay characteristic allows it to tolerate normal motor inrush currents without nuisance opening while still responding quickly to sustained overloads and fault conditions. Its indicating feature is particularly useful in multi-fuse panel installations where visual confirmation of fuse status reduces troubleshooting time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRK1 class cartridge fuse with dual-element time delay design\u003c\/li\u003e\n  \u003cli\u003e70-amp rating with 100 kA DC and 300 kA AC (RMS) interrupting capacity\u003c\/li\u003e\n  \u003cli\u003eIndicating function provides visible blown-fuse notification\u003c\/li\u003e\n  \u003cli\u003eBolt-on mount type for secure, vibration-resistant installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7-7\/8 inches for standard fuse block compatibility\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA Certified, and UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK1 cartridge fuse holders and fuse blocks accepting a 70-amp, 7-7\/8-inch bolt-on time delay fuse.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before replacing any fuse. Verify the fuse holder or fuse block is rated for Class RK1 cartridges and confirm the voltage and amperage ratings of the replacement fuse match the circuit requirements. Do not use a fuse with a higher amperage rating than the circuit is designed to carry.\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: 70 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\u003eIndicating\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity (DC)\u003c\/strong\u003e: 100 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity (AC RMS)\u003c\/strong\u003e: 300 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-7\/8 inches (200 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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\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: LPS-RK-70SPI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51723089346866,"sku":"LPS-RK-70SPI","price":278.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d0c6df1c1d7da4b97622704892ba3d1_0c3a4b50-d064-4adf-bcd7-0341abc82f4e.jpg?v=1788600445","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-lps-rk-70spi-rk1-time-delay-fuse-70a","provider":"Voomi Supply","version":"1.0","type":"link"}
