What are the Classifications of Fuses
There are many types of fuses, including classification by protection form, scope of use, volume, rated voltage, breaking capacity, and fusing speed. Below, we will introduce the classification by type, which can be divided into current fuses: patch fuse, miniature fuses, plug-in fuses, and tubular fuses; Temperature fuse: RH square type, RP resistance type, RY metal case; Self recovery fuse: plug-in, laminated, patch.
1、Current fuse
Chip fuse. There are specifications such as 0805 and 1206, which use thin film technology to accurately control electrical characteristics. Due to its small size, it is an ideal choice for providing secondary protection for circuits in space limited applications, such as handheld portable electronic devices and various instruments and meters.
2、Temperature fuse
It is an irreparable disposable thermal protection device, available in RH, RF, RY, and other series. The product has a delicate appearance and structure, good sealing performance, sensitive and reliable operating temperature, small impact of current shock, and vibration resistance. It is mainly used in electric fans, rice cookers, electric fryers, disinfection cabinets, etc.
3、Self recovery fuse
This is a type of fuse that can automatically recover due to eXCessive current causing an open circuit in the circuit. It belongs to the multiple-use type and is suitable for overload protection circuits.
