Its very fast-acting response helps you to stop fault currents quickly, which can help reduce damage to connected components and better protect systems during electrical faults.\u003c\/p\u003e\n\u003cp\u003eBuilt with a knife-blade style design, the TJN400 provides a solid connection in compatible fuse holders while taking up minimal space inside electrical panels and switchboards. With a 200 kA interrupting rating at 300 VAC, it’s commonly used in commercial and industrial power systems that require high-fault-current protection. The non-indicating design keeps installation and replacement simple for standard Class T fuse applications.\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\u003e400 amp Class T fuse:\u003c\/strong\u003e Designed to provide overcurrent protection for electrical systems requiring a 400 amp fuse rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery fast-acting protection:\u003c\/strong\u003e Helps stop fault currents quickly to reduce potential damage to connected equipment during electrical faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-limiting performance:\u003c\/strong\u003e Supports protection of electrical systems by limiting the amount of fault current that passes through the circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnife-blade style construction:\u003c\/strong\u003e Provides a secure connection in compatible fuse holders while supporting reliable installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact design for tighter spaces:\u003c\/strong\u003e Helps maximize available room inside electrical panels and switchboards where space may be limited.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200 kA interrupting rating at 300 VAC:\u003c\/strong\u003e Suitable for commercial and industrial systems requiring high fault-current protection capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for commercial and industrial systems:\u003c\/strong\u003e Commonly used in power distribution equipment and other demanding electrical applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-indicating fuse:\u003c\/strong\u003e Keeps installation and replacement straightforward for standard Class T fuse applications.\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 TJN400\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Class T Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e TJN\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 300 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA.I.C.
