The Eaton Bussmann series JJS-400 is a 400A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For an application that requires this combination of amperage, voltage, fuse class, interrupting rating, connection style, and dimensions, it provides a clear specification match. It’s built to last, but correct fuse selection should always start with the equipment's requirements—not appearance or amperage alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e400A Class T configuration: Rated at 400 amps for compatible equipment specifically requiring this fuse class and amperage.\u003c\/li\u003e\n\u003cli\u003e600V rating: Provides a clear voltage rating for accurate application matching.\u003c\/li\u003e\n\u003cli\u003eBolted blade connections: Uses a bolted blade end x bolted blade end connection configuration.\u003c\/li\u003e\n\u003cli\u003eNon-indicating design: The fuse does not include an integral visual indicator of fuse status.\u003c\/li\u003e\n\u003cli\u003eEasy identification: Catalog number JJS-400 and UPC 051712628044 help technicians identify the exact component during replacement and maintenance.\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\u003eProduct Name:\u003c\/strong\u003e Eaton Bussmann Series JJS Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e JJS-400\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 T\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\u003eVoltage Rating:\u003c\/strong\u003e 600V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 200 kAIC at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Bolted Blade End x Bolted 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 Non-Indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Length\/Depth:\u003c\/strong\u003e 3.63 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 1 in.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 1 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 051712628044\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\u003eManufacturer information lists the Eaton Bussmann JJS-400 as CE-marked and RoHS-compliant.
