Type of fuse

A fuse is a component that can fuse and cut off the current when the current abnormally rises to a certain height and heat, so as to protect the safe operation of the circuit. There are also many types of fuses.
According to the maintenance method, it can be divided into: overcurrent maintenance and overheating maintenance. The fuse used for over-current protection is the fuse often mentioned (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 and memory alloy type, etc. (Thermal fuse is used to prevent feverish appliances or fever-prone appliances from too high temperature and stop maintenance, such as: hair dryer, electric iron, electric rice Pots, electric stoves, transformers, electric ideas, etc.; it echoes the decrease in temperature rise of electrical appliances, and does not affect the size of the current in the task of the circuit. Its task is different from the "current limiting fuse").

According to the scale of application, it can be divided into: power fuses, machine tool fuses, electrical instrument fuses (electronic fuses), and automobile fuses.

According to the size, it can be divided into: large, medium, small and micro.

According to the extra voltage, it can be divided into: high voltage fuse, low voltage fuse and safety voltage fuse.

According to the breaking capacity, it can be divided into: high and low breaking capacity fuses.

According to the shape distinction, it can be divided into: flat-head tubular fuse (also can be divided into internal welding fuse and external welding fuse), pointed tubular fuse, guillotine fuse

Screw type fuses, blade type fuses, flat type fuses, wrap type fuses, chip type fuses.

According to the fuse speed, it can be divided into: ultra-slow fuse (normally used TT performance), slow-speed fuse (normally used T performance), medium-speed fuse (normally used M performance), fast fuse (normally used F performance), Very fast fuse (normally used FF performance).
According to the standard distinction, it can be divided into: European standard fuse, American standard fuse, Japanese standard fuse.
