Glass tube 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.
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.
