Rated for 400 Amps, this time-delay fuse is designed to handle the temporary power surges that happen when motors, transformers, and similar equipment start up, while still protecting circuits from overloads and short circuits. Its knife-blade design provides a secure connection, and the current-limiting construction helps reduce the amount of damage a fault can cause to connected equipment. With a 200 kA interrupting rating at 250 VAC, the TR400R is built for applications where dependable circuit protection is important day in and day out. Whether it’s used in a distribution panel, motor control center, or heavy electrical equipment, the TR400R helps keep systems protected and running with fewer interruptions.\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 R Fuse:\u003c\/strong\u003e Designed for industrial and commercial power systems requiring dependable overcurrent protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-Delay Operation:\u003c\/strong\u003e Helps prevent unnecessary fuse openings during startup surges caused by motors, transformers, and similar equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-Limiting Protection:\u003c\/strong\u003e Helps reduce equipment damage during faults by limiting the amount of fault current that passes through the circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnife-Blade Style Design:\u003c\/strong\u003e Provides a secure installation and dependable electrical connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Rating:\u003c\/strong\u003e Rated for 200 kA at 250 VAC for demanding commercial and industrial applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Construction:\u003c\/strong\u003e Compact size allows use in compatible electrical equipment and distribution systems.\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 TR400R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e TR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e Class R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 400A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 200 kA @ 250 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type:\u003c\/strong\u003e Time-Delay\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\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 8.63 in.\u003c\/li\u003e\n\u003cli\u003eWidth: 2.0 in.\u003c\/li\u003e\n\u003cli\u003eDepth: 2.0 in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShip Weight:\u003c\/strong\u003e N\/A\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\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Compliance:\u003c\/strong\u003e The TR400R is designed for low-voltage overcurrent protection applications commonly found in commercial and industrial electrical systems.
