Classification of insurance tubes
According to the form of protection, it can be divided into: over current protection and over temperature protection. A fuse for overcurrent protection is a commonly used fuse (also called a current limiting fuse). Fuses for overheat protection are commonly referred to as "temperature fuses." The temperature fuse is further divided into a low-melting alloy shape and a temperature-sensing shape and a memory alloy shape and the like. (The temperature fuse is to prevent the temperature of the heating appliance or the heat-generating appliance from being too high for protection. It responds to the rise of the temperature rise of the electrical appliance, and does not care about the working current of the circuit. The working principle is different from the "current limiting fuse". .)
According to the scope of use, it can be divided into: power fuses, machine tool fuses, electrical instrument fuses (electronic fuses), car fuses.
According to the volume, it can be divided into: large, medium, small and miniature.
According to the rated voltage, it can be divided into: high voltage fuse, low voltage fuse and safe voltage fuse.
According to the breaking ability, it can be divided into: high and low breaking capacity fuses.
According to the shape, it can be divided into: flat-head tubular fuse (also can be divided into internal welding fuse and external welding fuse), pointed tubular fuse, sickle fuse, spiral fuse, blade fuse, flat fuse, wrap Fuse, chip fuse.
According to the material, it can be divided into: glass fuse tube, ceramic fuse tube.
According to the fusing speed, it can be divided into: special slow fuse (usually indicated by TT), slow fuse (generally denoted by T), medium speed fuse (generally denoted by M), fast fuse (generally denoted by F), special Fast fuse (usually indicated by FF).
According to the standard, it can be divided into: European standard fuse (VDE), American standard fuse (UL), Japanese standard fuse (PSE).
According to the type, it can be divided into: current (chip fuse, micro fuse, blade fuse, tubular fuse), thermal fuse (RH [square], RP [resistive], RY [metal shell]), self-recovery fuse (plug-ins, laminations, patches)
According to the size can be divided into: patch type 0603, 0805, 1206, 1210, 1812, 2016, 2920; non-patch type Φ2.4 × 7, Φ3 × 7, Φ 3.6 × 10, Φ4.5 × 15, Φ5 .0×20, Φ5.16×20, Φ6×25, Φ6×30, Φ6×32, Φ8.5×8, Φ8.5×8×4, Φ10×38, Φ14×51.
