Slow Blow Fuse works by breaking the circuit when rated current passes through it. When the current passing through the fuse exceeds the rated current, the thin wire melts and breaks the circuit.
There are two basic types of fuses available for appliances and consumer electronics: quick blow or time-delay. Any replacement fuse must match the one it’s replacing. In general, quick blow fuses are a single strand of wire or strip of metal. Time-delay fuses usually have a coiled wire, a thick element wrapped in wire, or a spring. Most electronic fuses will have the voltage and amp rating stamped on the end cap. The type of fuse can generally be visually identified. Also, owner’s manuals will have the correct replacement fuse generically identified. For example: “Use a 2 amp, time-delay, 250 volt fuse.”
The glass tube fuse protects the outside environment when the metal inside melts as high temperature can build up. Glass being transparent, helps to visually inspect the fuse to make sure if it is blown.
The resistance of a given length of flat fuse wire is inversely proportional to it's thickness. A fuse burns open as a result of Watts generated by the current through the fuse squared times the resistance of the fuse. The Watts are dissipated by the fuse resistance in the form of heat and heat is what burns the fuse open. Therefore increasing the thickness of a given fuse wire lowers the fuse resistance and thereby increases the amount of current the fuse can carry without generating enough heat to burn the fuse open.
Glass tube fuses are often used to protect appliances and consumer electronics. As electronic equipment becomes smaller, the circuits and components become more delicate and easily damaged. Fuses are the preferred method of protection due to their accuracy, small size and reliability. Fuses are available in a wide variety of amp ratings to provide precise protection. Generally, two sizes of user-replaceable fuses are found: the 1/4” x 11/4” and 5 x 20mm. Each is available in a variety of volt and amp ratings.
All fuses have a voltage rating. To maintain safety, this voltage rating should not be exceeded in application, although it is acceptable to use a higher rated fuse in a lower voltage application. For example: A fuse rated for 125 volts is appropriate in household (110V) or automotive (12V), while a fuse rated for 32 volts is appropriate for automotive (12V), but not for household (125V). Always replace a fuse with one of the same or higher voltage rating.
