Part of the JTD Series and identified within the POWR-PRO Fuse family, it features knife-blade construction and a Slo-Blo\/Time Lag (T)\/Time Delay opening characteristic. This is a non-indicating fuse, so check this detail along with the electrical ratings when replacing an existing fuse. A 250A rating may be the first thing you notice. Still, it shouldn't be the only thing you match—Class J requirements, time-delay operation, voltage, interrupting ratings, knife-blade format, and holder compatibility all deserve a careful check.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e250A continuous current rating for equipment requiring a 250-amp fuse\u003c\/li\u003e\n\u003cli\u003eClass J configuration provides a clearly defined fuse class for compatibility checks\u003c\/li\u003e\n\u003cli\u003eTime-delay opening characteristic, specified as Slo-Blo\/Time Lag (T)\/Time Delay\u003c\/li\u003e\n\u003cli\u003eMaximum voltage rating of 600VAC\u003c\/li\u003e\n\u003cli\u003eMaximum DC voltage rating of 500VDC\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction makes the physical format straightforward to verify against the existing fuse and equipment\u003c\/li\u003e\n\u003cli\u003ePart of the JTD Series\u003c\/li\u003e\n\u003cli\u003eIdentified as a POWR-PRO Fuse family product\u003c\/li\u003e\n\u003cli\u003eNon-indicating design for equipment specifications that call for this configuration\u003c\/li\u003e\n\u003cli\u003eMounting method is specified as fuse block, clip, or holder\u003c\/li\u003e\n\u003cli\u003eLFJ60400 Series is the specified holder family\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\u003eCatalog Number:\u003c\/strong\u003e JTD250\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e JTD\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Description:\u003c\/strong\u003e FUS 600V T\/D CLASS J 250A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Class J Time-Delay Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 250A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class J\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Characteristic:\u003c\/strong\u003e Slo-Blo \/ Time Lag (T) \/ Time Delay\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum AC Voltage:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum DC Voltage:\u003c\/strong\u003e 500VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Value 1:\u003c\/strong\u003e 200,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Interrupting Value 2:\u003c\/strong\u003e 300,000A at 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Interrupting Rating:\u003c\/strong\u003e 20,000A at 500VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublished Interrupting Rating:\u003c\/strong\u003e 20 kA at 500VDC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction \/ Size:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily Style:\u003c\/strong\u003e POWR-PRO Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicating:\u003c\/strong\u003e No\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method:\u003c\/strong\u003e Fuse Block \/ Clip \/ Holder\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecified Holder Series:\u003c\/strong\u003e LFJ60400 Series\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\u003eThe supplied manufacturer information confirms the JTD250's Class J designation, 250A current rating, voltage and interrupting specifications, time-delay opening characteristic, knife-blade construction, non-indicating configuration, and mounting information.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe JTD250 suits electrical equipment designed for a 250A Class J time-delay, non-indicating fuse with matching electrical and physical requirements.
