The fuse tube is an electrical element that ensures the safe operation of the circuit and is one of the fuses. The glass tube fuse can effectively prevent the molten metal from splashing on other devices, and also insulate the high temperature. The common glass tube fuse is often used in electronic circuit boards with dense components. It can also be installed in the wire, plug or special fuse seat because it is convenient for quick replacement and maintenance; The closed safety tube can also be used for equipment in explosion-proof places. 4.5*10mm fast-below glass tube fuse Glass tube fuses can be divided into special slow speed fuses (generally expressed as TT), slow speed fuses (generally expressed as T), medium speed fuses (generally expressed as M), fast speed fuses (generally expressed as F), and special fast speed fuses (generally expressed as FF) according to the fusing speed. The diameter of glass tube is generally φ 5mm, 5X20mm are the most conventional glass tube fuses...
