The MDL designation identifies this as a slow-blow fuse designed to tolerate brief inrush currents without nuisance opening, making it well suited for electronic controls and instrumentation circuits. The glass tube body measures 1\/4 inch in diameter by 1-1\/4 inch in length, a standard form factor stocked by most electrical and HVAC supply houses. Licensed electricians and electronics technicians are the primary installers, though HVAC technicians frequently encounter this fuse in low-voltage control boards and electronic equipment.\u003c\/p\u003e\n\u003cp\u003eThis fuse is used in electronic equipment, control panels, and instrumentation where a time delay characteristic is required to ride through momentary surge currents at startup. The 250-volt rating covers both standard 120-volt and 240-volt circuits within its amperage class. The carded 2-pack format is intended for retail and trade counter sales, providing a spare on hand for field service calls where a single fuse replacement is the common repair task.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType MDL time delay (slow-blow) characteristic tolerates inrush current without nuisance opening\u003c\/li\u003e\n  \u003cli\u003eGlass tube body allows visual inspection of the fuse element without a meter\u003c\/li\u003e\n  \u003cli\u003eStandard 1\/4 inch x 1-1\/4 inch body fits commonly available fuse holders and panels\u003c\/li\u003e\n  \u003cli\u003e250-volt rating suitable for both 120-volt and 240-volt electronic control applications\u003c\/li\u003e\n  \u003cli\u003eSold as a carded 2-pack for convenient field carry and immediate spare availability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement for Type MDL time delay glass tube fuses in electronic equipment, control panels, and instrumentation using 1\/4 inch x 1-1\/4 inch fuse holders rated up to 250 volts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFuse replacement should be performed by a qualified electrician or service technician. Always de-energize the circuit and verify with a meter that voltage is absent before removing or inserting a fuse. Confirm that the replacement fuse matches the exact amperage, voltage, and time delay type specified on the equipment nameplate or wiring diagram. Never substitute a higher-amperage fuse or a fast-blow type where a time delay fuse is specified, as this can damage equipment or create a safety hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 4 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 Type\u003c\/strong\u003e: MDL Time Delay (Slow-Blow)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Glass Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Size\u003c\/strong\u003e: 1\/4 inch x 1-1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 fuses per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.3 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: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BP\/MDL-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":51557966610738,"sku":"BP\/MDL-4","price":37.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f086e91897d1bf3651f4460d6153702f.jpg?v=1786399704","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-bp-mdl-4-time-delay-glass-fuse-4a-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
