With an 800 A rating and a 200 kA interrupting capacity at 300V AC, this fuse is built to respond quickly to overloads and short circuits, helping protect connected equipment from costly damage. Its very fast-acting design makes it a solid option for applications where sensitive electrical components need dependable fault protection. The compact knife-blade style body allows the TJN800 to fit into tighter electrical setups without sacrificing performance. Because it’s a non-indicating fuse, it works well in systems where simple, reliable overcurrent protection is the priority. It’s commonly used in switchboards, control panels, motor circuits, and other power distribution equipment where high fault current may be present.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e800 amp Class T fuse:\u003c\/strong\u003e Designed for high-amperage electrical protection in commercial and industrial systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery fast-acting response:\u003c\/strong\u003e Responds quickly to overloads and short circuits for dependable fault protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-limiting protection:\u003c\/strong\u003e Helps reduce electrical damage to connected equipment during fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200 kA interrupting rating at 300V AC:\u003c\/strong\u003e Built for applications where high fault current may be present.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnife-blade style design:\u003c\/strong\u003e Allows secure installation while maintaining a compact form factor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact size:\u003c\/strong\u003e Fits into tighter electrical setups without sacrificing performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-indicating fuse construction:\u003c\/strong\u003e Ideal for systems where simple, reliable overcurrent protection is the priority.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\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\u003ePart Number:\u003c\/strong\u003e TJN800\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e TJN\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:\u003c\/strong\u003e 800A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 300V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA @ 300V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication:\u003c\/strong\u003e Non-Indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e Very Fast-Acting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 3.375 in.\u003c\/li\u003e\n\u003cli\u003eWidth: 2.062 in.\u003c\/li\u003e\n\u003cli\u003eDepth: 2.062 in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Applications:\u003c\/strong\u003e The TJN800 is designed for use in electrical systems that require high interrupting capacity and fast overcurrent protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDependable Protection:\u003c\/strong\u003e It is manufactured for applications where dependable circuit protection and current limitation are important for equipment safety and system performance.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis fuse is a good fit for industrial facilities, commercial buildings, OEM equipment, and electrical distribution systems.
