It is designed for general-purpose overcurrent protection in feeder and branch-circuit applications. The fuse provides a maximum interrupting rating of 50 kA, safely clearing available short-circuit currents across all standard ratings. It is not a rejection-style fuse, so installers must verify that any replacement maintains an equal or greater interrupting rating than the original device. Electricians install this fuse in clip-style fuse holders found in panels, disconnects, and fused safety switches.\u003c\/p\u003e\n\u003cp\u003eThe OT60 ONE T is suited for residential and light commercial feeder and branch-circuits serving lighting loads, heating equipment, and other non-motor electrical loads. It carries an AC\/DC rating, making it usable in both alternating-current and direct-current circuits within its voltage limits. The fuse is compliant with RoHS requirements and operates at 50 and 60 Hz. For Canadian installations, OTN-series fuses in the 15-60 ampere range satisfy the Canadian Electrical Code requirement for Type P low melting-point, non-time-delay fuses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60A fast-acting operation provides immediate response to short-circuit conditions without intentional delay\u003c\/li\u003e\n  \u003cli\u003e50 kA AC maximum interrupting rating for reliable short-circuit protection on feeder and branch circuits\u003c\/li\u003e\n  \u003cli\u003eDual-rated 250 volts AC and 250 volts DC for flexible application in AC and DC systems\u003c\/li\u003e\n  \u003cli\u003eFerrule connection type with copper terminals for secure clip-mount installation\u003c\/li\u003e\n  \u003cli\u003ePaper body construction suitable for general-purpose, non-motor load applications\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant for installations with environmental material restrictions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class K5 fast-acting ferrule fuses in clip-style fuse holders rated for general-purpose feeder and branch-circuit protection.\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 any applicable local codes. De-energize and lock out the circuit before removing or installing the fuse. This is a one-time fuse and must be replaced after any overcurrent event. Verify that the replacement fuse matches or exceeds the interrupting rating of the original to avoid creating a hazard on high available fault-current circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: Class K5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 60 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Voltage AC (UL)\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Voltage DC (UL)\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed \/ Characteristic\u003c\/strong\u003e: Fast-Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAC Max Interrupting Rating\u003c\/strong\u003e: 50 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAC or DC\u003c\/strong\u003e: AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection \/ Terminal Type\u003c\/strong\u003e: Ferrule\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection \/ Terminal Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody \/ Insulating Material\u003c\/strong\u003e: Paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Clip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.073 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\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: OT60 ONE T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERSEN","offers":[{"title":"Default Title","offer_id":51347477365042,"sku":"OT60 ONE T","price":21.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552989.jpg?v=1782106194","url":"https:\/\/voomisupply.com\/products\/mersen-ot60-one-t-class-k5-60a-250v-fast-acting-fuse","provider":"Voomi Supply","version":"1.0","type":"link"}
