The TRS300R is built for exactly that kind of environment—delivering dependable protection where heavy loads and fault currents are part of the job. Rated at 300 amps with a 200 kA interrupting capacity at 600VAC, this Class R fuse is designed to step in fast when it counts, limiting damage and helping keep your equipment online. What makes this fuse especially useful is its time-delay feature. It won’t trip unnecessarily during normal startup surges—like when motors kick on—but it still reacts quickly to real faults. The knife-blade design gives you a solid, secure fit in compatible holders, and the non-indicating style keeps things simple and durable without extra components that can fail over time. It’s a practical, no-nonsense solution for serious electrical protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHandles up to 200kA interrupting capacity at 600VAC: for high-fault environments\u003c\/li\u003e\n\u003cli\u003eTime-delay design helps prevent nuisance blowing during equipment startup\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting protection reduces potential damage during short circuits\u003c\/li\u003e\n\u003cli\u003eKnife-blade construction ensures a firm, reliable connection\u003c\/li\u003e\n\u003cli\u003eNon-indicating design keeps maintenance straightforward\u003c\/li\u003e\n\u003cli\u003eBuilt to fit Class R rejection-style fuse holders for proper system matching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e TRS300R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 300A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Time-Delay, Current-Limiting Fuse\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\u003eFrame Type:\u003c\/strong\u003e TRS\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 11.63 in\u003c\/li\u003e\n\u003cli\u003eWidth: 2.54 in\u003c\/li\u003e\n\u003cli\u003eDepth: 2.54 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e Not available\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\u003eIndustry Standards:\u003c\/strong\u003e This fuse is manufactured in line with recognized industry standards for overcurrent protection, including compliance with applicable UL and NEC requirements.
