This cylindrical fuse combines the low I2t thermal energy let-through of a semiconductor fuse with the branch circuit performance characteristics of a UL-listed Class J fuse, making it ideal for protecting sensitive electronic components such as IGBTs, DC capacitors, diodes, and SCRs during circuit fault conditions. The HSJ450 features current-limiting capability, excellent cycling ability for frequent motor controller start-ups, and optimized overload protection down to 135% of fuse rating. \u003cb\u003eKey Specifications\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003ePart Number: HSJ450\u003c\/li\u003e\n\u003cli\u003eAmperage Rating: 450A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 600VAC \/ 500VDC\u003c\/li\u003e\n\u003cli\u003eFuse Class: Class J\u003c\/li\u003e\n\u003cli\u003eSpeed Type: High Speed\u003c\/li\u003e\n\u003cli\u003eInterrupt Rating: 200kA AC \/ 100kA DC\u003c\/li\u003e\n\u003cli\u003eBody Style: Cylindrical\u003c\/li\u003e\n\u003cli\u003eLength: 8 inches\u003c\/li\u003e\n\u003cli\u003eDiameter: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003eUL Listed to Standard 248-8\u003c\/li\u003e\n\u003cli\u003eCSA Certified to Standard C22.2\u003c\/li\u003e\n\u003c\/ul\u003eAt \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: HSJ450\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Mersen\u003c\/li\u003e\n\u003cli\u003eBrand : Mersen\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Low Voltage Fuse\u003c\/li\u003e\n\u003cli\u003eFamily : High Speed\u003c\/li\u003e\n\u003cli\u003eType : HSJ\u003c\/li\u003e\n\u003cli\u003eVoltage : 600\u003c\/li\u003e\n\u003cli\u003eAmperage : 450\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@600V\u003c\/li\u003e\n\u003cli\u003eDiameter : 2.5\u003c\/li\u003e\n\u003cli\u003eClass Rating : J\u003c\/li\u003e\n\u003cli\u003eBarrels : 1\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUPC : 78200132973\u003c\/li\u003e\n\u003cli\u003eGTIN : 00782001329730\u003c\/li\u003e\n\u003cli\u003eWeight : 1 \u003c\/li\u003e\n\u003cli\u003eCertification : UL, CSA\u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Mersen","offers":[{"title":"New","offer_id":45106310447263,"sku":"HSJ450-New","price":2231.61,"currency_code":"USD","in_stock":true},{"title":"Re-Certified","offer_id":45106310480031,"sku":"HSJ450-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/HSJ450_0.jpg?v=1724996965","url":"https:\/\/essentialparts.com\/products\/hsj450-mersen-450a-600vac-high-speed-class-j-fuse","provider":"Essential Electric Supply","version":"1.0","type":"link"}
