The general classification and zoning of fuses are generally based on eight levels: protection method, application scope, volume size, rated current, final breaking capacity, external characteristics, melting rate, and standard.
1. Classification by protection method
There are two types of fuse protection: overcurrent protection and overtemperature protection; The fuse used for overcurrent protection is the overcurrent protection fuse, and the fuse used for over temperature protection is the temperature fuse. Temperature fuses are also divided into low melting point alloy shapes, temperature sensor open shapes, memory alloy shapes, etc. Temperature fuses are used to protect appliances that are hot or prone to overheating. They respond to the rise in temperature of electrical appliances and do not easily pay attention to the size of electrical flow in the operation of power circuits. Their principle is different from the "overcurrent protection fuse".
2. Classification by application category
Fuses are divided into four categories based on their application categories: power engineering fuses, CNC lathe fuses, electrical instrument panel fuses, and vehicle fuses.
3. Classification based on volume
Fuses are classified into four categories based on capacitance: large and medium-sized, medium and small, medium and small, and small.
4. Classification by rated current
Fuses are divided into three categories based on their operating voltage: high voltage fuses, low voltage fuses, and operating voltage fuses.
5. Classification by final breaking capacity
Fuses are divided into two types based on their final breaking capacity: high breaking capacity fuses and low breaking capacity fuses.
Under what circumstances can it be clear that the vehicle fuse is broken?
When the car's cigarette lighter, window glass, central air conditioning, headlights, and other electrical appliances fail independently, when the power switch is turned on, the sound of current or relay posture can be heard, which can be roughly judged as a broken fuse.
