The Eaton Bussmann series LPN-RK-400SP is a 400A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies an interrupting rating of 300 kAIC at 250VAC and 100 kAIC at 250VDC, with dual-element construction and a blade-end × blade-end connection. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-400SP 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\u003e400A Class RK1 configuration: Combines a 400-amp rating with the manufacturer's specified Class RK1 design for compatible applications.\u003c\/li\u003e\n\u003cli\u003e250VAC and 250VDC ratings: The same nominal voltage rating applies to both AC and DC applications, while the applicable interrupting ratings differ.\u003c\/li\u003e\n\u003cli\u003eTime-delay operation: Eaton identifies the LPN-RK-400SP as a time-delay fuse, an important operating characteristic to match with the equipment being protected.\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design: Provides the manufacturer-specified current-limiting characteristic required for appropriate applications.\u003c\/li\u003e\n\u003cli\u003eDual-element construction: Uses Eaton's specified dual-element configuration.\u003c\/li\u003e\n\u003cli\u003eBlade end × blade end connection: Gives technicians a defined connection configuration to check when confirming physical compatibility.\u003c\/li\u003e\n\u003cli\u003eNon-indicating configuration: Eaton identifies this catalog number as non-indicating.\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-400SP\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 400A\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 250VDC\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 250VDC\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\u003eConnection:\u003c\/strong\u003e Blade End × Blade End\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-Indicating\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 8.63 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 2.36 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 2.36 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 1.75 lb.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 051712538558\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE Marked:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS Compliance:\u003c\/strong\u003e Identified by Eaton as RoHS Compliant\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 supplied specifications, the LPN-RK-400SP is CE Marked and RoHS Compliant.
