Rated at 250 VAC and 0.8 amps, this fuse provides overcurrent protection for low-amperage control circuits within the boiler assembly. Time delay fuses are engineered to tolerate brief inrush currents during startup without nuisance tripping, while still opening reliably under sustained fault conditions. Licensed HVAC and boiler technicians typically handle this replacement during routine service or after a fault event. It is a direct OEM-specified component for the Lochinvar Knight fire tube boiler line.\u003c\/p\u003e\u003cp\u003eThis fuse is specified for use with the Lochinvar Knight Model KH55 to 285 Fire Tube Boiler series. It fits into the boiler control circuit and is typically accessed during a service call when control board diagnostics point to a blown fuse or when performing a post-fault inspection. This is a low-voltage, low-amperage protective device and should be replaced only with a fuse of identical rating to maintain proper circuit protection and system safety.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTime delay design tolerates startup inrush without nuisance tripping\u003c\/li\u003e\n\u003cli\u003eRated 250 VAC for compatibility with standard boiler control circuits\u003c\/li\u003e\n\u003cli\u003e0.8 amp rating provides precise overcurrent protection for sensitive control components\u003c\/li\u003e\n\u003cli\u003eOEM-specified part for Lochinvar Knight KH55 to 285 Fire Tube Boilers\u003c\/li\u003e\n\u003cli\u003eDirect replacement minimizes diagnostic complexity during service calls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSpecified for use with the Lochinvar Knight Model KH55 to 285 Fire Tube Boiler series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFuse replacement on a fire tube boiler should be performed by a licensed HVAC or boiler technician. Before servicing, shut off all electrical power to the boiler at the disconnect switch and allow the unit to cool if it has been operating. Always replace with a fuse of the exact same voltage and amperage rating — substituting a higher-rated fuse can damage control components or create an unsafe condition. Verify the root cause of the blown fuse before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 250 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 0.8 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LOCHINVAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L100208808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":51346299420978,"sku":"L100208808","price":19.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/100208808.jpg?v=1782076780","url":"https:\/\/voomisupply.com\/products\/lochinvar-l100208808-time-delay-fuse-250v-0-8a","provider":"Voomi Supply","version":"1.0","type":"link"}
