Breaking capacity of current fuse
Classification of fusesAccording to the protection form, it can be divided into: overcurrent protection and overheating protection. The fuse used for over-current protection is the usual fuse (also called current-limiting fuse). The fuse used for overheating protection is generally called "thermal fuse". Thermal fuse is divided into low melting point alloy type, temperature sensitive trigger type, memory alloy type and so on. (Thermal fuse is to prevent heating appliances or heat-prone appliances from overheating to protect them. For example: hair dryers, electric irons, rice cookers, electric stoves, transformers, motors, etc.;
It responds to the increase in temperature of electrical appliances and does not care about the working current of the circuit. Its working principle is different from "current fuse").
According to the scope of use: Power fuses, machine tool fuses, electrical instrument fuses (electronic fuses), automotive fuses.
By volume: Large, medium, small and micro.
According to rated voltage: high voltage fuse, low voltage fuse and safety voltage fuse.
According to the breaking capacity: high and low breaking capacity fuses.
Breaking speed of the fuse: Very slow fuse (usually represented by TT), Slow fuse (usually represented by T), Medium-speed fuse (usually denoted by M), Fast fuse (usually denoted by F), Very fast fuse (usually represented by FF).
According to the standard: European standard fuse, American standard fuse, Japanese standard fuse.
Classified by type: current fuse (chip fuse, miniature fuse, blade fuse, tubular fuse),
Thermal fuse (RH[block type], RP[resistance type], RY[metal shell]);
Recoverable fuse (plug-in, patch type).
According to the size, it can be divided into:Patch type: 0603, 0805, 1206, 1210, 1812, 2016, 2920;
Lead type: Φ2.4×7, Φ3×7, Φ3.6×10, 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.
