It provides overcurrent protection in control circuits, small appliances, HVAC equipment, and light commercial electrical panels. The fast-acting response characteristic means it opens quickly on overload, protecting sensitive downstream components. Licensed electricians and HVAC service technicians install this fuse type as a direct replacement during routine maintenance or troubleshooting of blown-fuse conditions.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and light commercial applications where a 0.25 x 1.25-inch glass cartridge fuse is specified. Common install scenarios include low-voltage control boards, transformer secondary circuits, and equipment protection circuits that require a fast-acting response at or below 1.5 amps and 250 volts. Always verify the equipment nameplate or service manual for the correct amperage and voltage rating before installing a replacement fuse.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFast-acting response for immediate overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eRated 1.5 amps at 250 volts\u003c\/li\u003e\n  \u003cli\u003eStandard 0.25 x 1.25-inch glass body — widely compatible form factor\u003c\/li\u003e\n  \u003cli\u003eGlass construction allows visual inspection of the fuse element without removal\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions: 1.15 inches long x 0.3 inches wide x 0.2 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-size replacement for equipment requiring a 0.25 x 1.25-inch fast-acting glass cartridge fuse rated at 1.5 amps and 250 volts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways de-energize and lock out the equipment before replacing a fuse. Confirm the replacement fuse matches the original amperage, voltage, and speed rating — substituting a higher amperage or slow-blow fuse can damage equipment or create a fire hazard. Use an appropriate fuse puller for cartridge fuse holders to avoid contact with live terminals. Fuse replacement in electrical panels or control boards should be performed by a qualified electrician or licensed HVAC technician in accordance with NFPA 70 (NEC) requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 1.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 250 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Fast Acting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 0.25 x 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\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: HARDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5581\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARDT","offers":[{"title":"Default Title","offer_id":51672474517810,"sku":"005581","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc452cef8abf7deee7c5623eac16d7e1.gif?v=1787967867","url":"https:\/\/voomisupply.com\/products\/hardt-5581-glass-fuse-1-5a-250v-fast-acting-0-25x1-25-in","provider":"Voomi Supply","version":"1.0","type":"link"}
