It is designed for general-purpose overcurrent protection in industrial and commercial electrical systems. The fuse features a two-element construction that provides time delay characteristics, allowing temporary inrush currents to pass without nuisance tripping while still protecting against sustained overloads and short circuits. It measures 5 inches in overall length with a 20.6 mm diameter body. Interrupting capacity is rated at 100 kA DC and 300 kA AC (RMS). Licensed electricians install this fuse as part of panel, feeder, or branch circuit protection schemes.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for use in fuse holders accepting Class RK1 cartridge fuses. Typical applications include motor branch circuit protection, industrial machinery, and commercial electrical distribution panels where time delay characteristics are required to ride through motor start inrush or transformer magnetizing currents. The non-indicating design is standard for installations where downstream monitoring equipment tracks fault events. This part is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK1 time delay cartridge fuse rated at 3.2 amps\u003c\/li\u003e\n  \u003cli\u003eTwo-element construction supports time delay operation for motor and transformer circuits\u003c\/li\u003e\n  \u003cli\u003eHigh interrupting capacity: 100 kA at DC, 300 kA at AC (RMS)\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5 inches (127 mm) with 20.6 mm body diameter\u003c\/li\u003e\n  \u003cli\u003eNon-indicating design for standard fuse holder installation\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA Certified (C22.2 No. 248.12, Class 1422-02, File 53787), and UL Listed (Guide JDDZ, File E4273)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fuse holders and disconnect switches rated for Class RK1 cartridge fuses.

De-energize and lock out the circuit before removing or installing fuses. Use properly rated fuse pullers when handling cartridge fuses to avoid arc flash exposure. Confirm the fuse holder ampere and voltage ratings match the circuit requirements before installing.\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: 3.2 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 Capacity (AC RMS)\u003c\/strong\u003e: 300 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity (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\u003eWeight\u003c\/strong\u003e: 0.15 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-3-2\/10SP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51689639248178,"sku":"LPS-RK-3-2\/10SP","price":82.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34a62a600f0b84fb0e537390348129e9.jpg?v=1788262273","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-lps-rk-3-2-10sp-cartridge-time-delay-fuse-rk1","provider":"Voomi Supply","version":"1.0","type":"link"}
