Class H fuses provide overcurrent protection by interrupting fault current before downstream components are damaged. The NON-450 is a non-renewable fuse, meaning it must be replaced after a fault event rather than re-fused. At 2.68 pounds, this is a substantial fuse intended for high-amperage applications. Licensed electricians and maintenance electricians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThe NON-450 is suited for use in disconnect switches, motor circuits, distribution panels, and industrial equipment where 250-volt, 450-amp overcurrent protection is required. Typical applications include large motor branch circuits, HVAC equipment disconnects, and industrial feeder protection. Class H fuses are widely used where high-fault-current interrupting capacity is not required and circuit conditions are well-controlled.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e450-amp current rating for high-load branch circuit and feeder applications\u003c\/li\u003e\n  \u003cli\u003e250-volt AC voltage rating suitable for standard single-phase and three-phase distribution systems\u003c\/li\u003e\n  \u003cli\u003eClass H one-time (non-renewable) cartridge construction\u003c\/li\u003e\n  \u003cli\u003eDirect replacement form factor for standard Class H fuse holders and disconnect blocks\u003c\/li\u003e\n  \u003cli\u003eWeighs 2.68 pounds — appropriate for large-format fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Class H cartridge fuse holders and disconnect switches rated for 450-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 NFPA 70 (NEC) requirements for overcurrent protection devices. Always de-energize and verify the absence of voltage using a calibrated meter before handling or replacing any fuse. Use appropriately rated fuse pullers and insulated tools when servicing Class H fuse holders. Never substitute a higher-amperage fuse to restore service without first identifying and correcting the fault condition.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 450 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 H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: One-Time (Non-Renewable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.68 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 05171230450\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NON-450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51383186784562,"sku":"NON-450","price":598.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678713.jpg?v=1782589064","url":"https:\/\/voomisupply.com\/products\/eaton-non-450-class-h-fuse-450a-250v","provider":"Voomi Supply","version":"1.0","type":"link"}
