Designed for reliable overcurrent protection in both AC and DC circuits, it delivers an interrupting rating of 50 kiloamperes AC and 20 kiloamperes DC. The cylindrical body measures 7.125 inches in length and 1.5625 inches in diameter, with blade terminals that seat securely into standard clip-type fuse holders. Licensed electricians and electrical contractors install this fuse as part of panel, feeder, and branch circuit protection work in residential and small commercial settings.\u003c\/p\u003e\n\u003cp\u003eThe OT200 is suited for feeder circuits, branch circuits, and resistive heating loads in residential and small commercial installations. Its fast-acting characteristics provide quick response to fault conditions, making it appropriate for applications where downstream equipment or wiring requires prompt overcurrent interruption. The single-use construction means the fuse must be replaced after any operation, which is standard practice for Class K5 one-time fuses of this type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass K5 fast-acting, one-time fuse construction for dependable overcurrent protection\u003c\/li\u003e\n  \u003cli\u003e200 amp current rating at 250 volts AC\/DC\u003c\/li\u003e\n  \u003cli\u003eInterrupting rating of 50 kiloamperes AC and 20 kiloamperes DC\u003c\/li\u003e\n  \u003cli\u003eBlade terminal type for use with standard clip-mount fuse holders\u003c\/li\u003e\n  \u003cli\u003ePaper\/polyester cylindrical body with copper and tin-plated copper contacts\u003c\/li\u003e\n  \u003cli\u003eEasy-to-read imprint label for quick field identification and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Class K5 replacement fuse for feeder, branch circuit, and resistive heating applications in residential and small commercial electrical systems with clip-type fuse holders rated for 250 volt, 200 amp service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and verify the circuit is dead before handling or replacing fuses. Confirm the fuse holder is rated for Class K5 blade-terminal fuses at the required voltage and amperage before installing. As a one-time fuse, the OT200 must be replaced after any overcurrent event and must not be bypassed or re-energized without full replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 200 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 volts AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 50 kiloamperes (AC), 20 kiloamperes (DC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class K5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharacteristics\u003c\/strong\u003e: Fast Acting, One Time\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Clip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Paper\/Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material\u003c\/strong\u003e: Copper\/Tin-Plated Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL 248-9, CSA C22.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.733 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\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: OT200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51283992412466,"sku":"OT200","price":122.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279135.jpg?v=1781065336","url":"https:\/\/voomisupply.com\/products\/mersen-ot200-class-k5-power-fuse-200a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
