The Eaton Bussmann series LPN-RK-40SP is a 40A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. Eaton specifies an interrupting rating of 300 kAIC at 250VAC and 100 kAIC at 125VDC, along with dual-element construction and a ferrule-end-to-ferrule-end connection. The manufacturer also specifies a 10-second response time at 500% and lists high in-rush current motor protection among the model's special features. When correctly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPN-RK-40SP is built to last as part of a properly designed and maintained electrical system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40A Class RK1 configuration: Combines a 40-amp rating with Eaton's specified Class RK1 fuse design for compatible equipment.\u003c\/li\u003e\n\u003cli\u003e250VAC \/ 125VDC ratings: Clearly defined AC and DC voltage ratings make it easier to match the fuse to the circuit requirements.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation: Eaton identifies this model as a time-delay fuse, an important characteristic when matching protection to equipment operating requirements.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: The LPN-RK-40SP is specified as a current-limiting fuse.\u003c\/li\u003e\n\u003cli\u003eDual-element construction: Uses the manufacturer's stated dual-element configuration.\u003c\/li\u003e\n\u003cli\u003e10 seconds at 500%: Eaton lists this response-time specification for the LPN-RK-40SP.\u003c\/li\u003e\n\u003cli\u003eFerrule-to-ferrule end connection: Provides a clear physical connection characteristic to verify against the existing fuse holder and equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Eaton\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family:\u003c\/strong\u003e Bussmann Series\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Eaton Bussmann Series LPN-RK Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e LPN-RK-40SP\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class RK1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 40A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Voltage Rating:\u003c\/strong\u003e 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Voltage Rating:\u003c\/strong\u003e 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Rating:\u003c\/strong\u003e 300 kAIC at 250VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 100 kAIC at 125VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e Time Delay; Current-Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e Dual\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 sec at 500%, as specified by Eaton\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Ferrule End × Ferrule End\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-Indicating, according to Eaton's dedicated Fuse Indicator field\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Feature:\u003c\/strong\u003e High In-Rush Current Motor Protection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\/Depth:\u003c\/strong\u003e 3 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 0.81 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 0.81 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 0.5 lb.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712538381\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE Marked:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAccording to Eaton's specifications, the Bussmann series LPN-RK-40SP is CE-marked.
