It’s designed to step in fast when there’s a short circuit, while still handling the normal surges that come with equipment starting up. Because it’s a time-delay fuse, it won’t trip every time you get a temporary inrush—like when a motor kicks on. That helps avoid unnecessary downtime. But when there’s an actual fault, it reacts quickly and limits the current before it can do real damage. This is a knife-blade style fuse, so it installs securely and stays put. No extra features, no indicators—just a straightforward, dependable fuse that does exactly what it’s supposed to do. If you’re working with feeders, transformers, or larger industrial setups, this is the kind of protection you want in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRated for 400 amps in demanding applications\u003c\/li\u003e\n\u003cli\u003e200 kA interrupting rating at 600VAC for high fault capacity systems\u003c\/li\u003e\n\u003cli\u003eTime-delay operation helps avoid nuisance trips\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design helps reduce damage during faults\u003c\/li\u003e\n\u003cli\u003eKnife-blade connection for a solid, reliable fit\u003c\/li\u003e\n\u003cli\u003eNon-indicating – simple and dependable\u003c\/li\u003e\n\u003cli\u003eClass R rejection feature adds an extra layer of safety\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 TRS400R\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:\u003c\/strong\u003e 600 VAC\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\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\u003eHeight:\u003c\/strong\u003e 11.63 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.54 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 2.54 in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Not listed\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\u003eBuilt to meet standard UL and CSA requirements for overcurrent protection, making it suitable for use in code-compliant electrical systems.\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\u003eIndustrial panels and distribution\u003c\/li\u003e\n\u003cli\u003eMotor control centers\u003c\/li\u003e\n\u003cli\u003eTransformer protection\u003c\/li\u003e\n\u003cli\u003eCommercial power systems\u003c\/li\u003e\n\u003cli\u003eHeavy equipment circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
