It combines a time-delay element with a current-limiting design, allowing it to ride through harmless temporary overloads such as motor inrush current while still opening quickly under genuine fault conditions. The copper construction supports reliable conductivity and thermal performance. Licensed electricians and electrical contractors install this fuse in branch circuit and feeder applications where both overload protection and short-circuit current limiting are required by code.\u003c\/p\u003e\n\u003cp\u003eThe TR200R is suited for residential and light commercial electrical panels, motor branch circuits, HVAC equipment disconnect protection, and similar 250-volt AC applications. Its dual element design makes it a practical choice where the connected load cycles on and off repeatedly, producing temporary high-current draws that a standard fuse would not tolerate without nuisance opening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e200 amp continuous rating at 250 volts AC\u003c\/li\u003e\n  \u003cli\u003eDual element time-delay construction tolerates motor inrush without nuisance blowing\u003c\/li\u003e\n  \u003cli\u003eCurrent-limiting Class RK5 rating reduces let-through energy during fault events\u003c\/li\u003e\n  \u003cli\u003eCopper construction for stable conductivity and long service life\u003c\/li\u003e\n  \u003cli\u003eUL Listed for use in branch circuit and feeder protection applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 fuse holders and disconnect blocks rated for 200 amp, 250-volt service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit completely before removing or installing any fuse. Verify the fuse holder and disconnect are rated for Class RK5 fuses at 250 volts and 200 amps before installation. Never install a fuse with a higher ampere rating than the circuit or equipment is designed to handle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 200 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class RK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Dual Element Time-Delay Current-Limiting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERSEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TR200R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":67581002744114,"sku":"TR200R","price":78.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7c0f55c9ca4c260c76b1af3043366ec.jpg?v=1792443233","url":"https:\/\/voomisupply.com\/products\/mersen-tr200r-200a-250v-class-rk5-time-delay-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
