It belongs to the Eaton Bussmann Series LPS-RK fuse family and is designed for branch circuit and feeder protection in commercial and industrial electrical systems. The dual-element construction separates the overload and short-circuit elements, allowing the fuse to ride through harmless temporary overloads while still providing fast, current-limiting response to damaging fault currents. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse class.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for motor branch circuit protection, transformer primary protection, and general-purpose feeder protection in panels and disconnect switches rated at 600 volts AC or 300 volts DC. The time-delay characteristic makes it well-matched to motor loads where inrush current during startup would otherwise cause nuisance openings. It is a non-indicating fuse, meaning it does not provide a visual blown indicator. The interrupting rating of 300 kA at 600 volts AC and 100 kA at 300 volts DC covers high available fault-current environments typical of commercial and light industrial service entrances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-element design separates overload and short-circuit response for motor and transformer circuit compatibility\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting action reduces let-through energy to downstream components during fault conditions\u003c\/li\u003e\n\u003cli\u003e300 kA interrupting rating at 600 volts AC for high fault-current environments\u003c\/li\u003e\n\u003cli\u003e100 kA interrupting rating at 300 volts DC\u003c\/li\u003e\n\u003cli\u003eClass RK1 classification provides tighter current-limiting performance compared to Class RK5\u003c\/li\u003e\n\u003cli\u003eNon-indicating construction with no external blown-fuse indicator\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Class RK1 replacement fuse for use in fusible disconnect switches, panelboards, and motor control equipment rated for 30-amp, 600-volt AC branch circuit or feeder applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and replacement of this fuse must be performed by a qualified electrician following applicable NEC requirements for overcurrent protection and safe work practices. Always de-energize and verify the absence of voltage on the circuit before handling fuses. Use an appropriately rated fuse puller when removing or installing Class RK1 fuses in fusible holders. Confirm that the fuse holder or disconnect is rated for Class RK1 fuses, as Class RK1 fuses are not interchangeable with holders designed only for Class RK5 or Class H fuses.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 30 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating (AC)\u003c\/strong\u003e: 600 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating (DC)\u003c\/strong\u003e: 300 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LPS-RK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Type\u003c\/strong\u003e: Time-delay, dual-element\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (AC)\u003c\/strong\u003e: 300 kA at 600 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (DC)\u003c\/strong\u003e: 100 kA at 300 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Non-indicating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BUSSMANN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LPS-RK30SP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":68060725772594,"sku":"LPS-RK30SP","price":54.21,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/bussmann-lps-rk30sp-30a-600v-class-rk1-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
