　　The response speed of a fuse is related to the operating temperature of the circuit where the fuse is installed, the fault current, and the heat dissipation of the device. The working environment of the circuit changes, such as when the working temperature of the circuit increases beyond the limit that the circuit can withstand, the fuse will act and blow. The higher the temperature of the circuit, the faster the response speed of the fuse, usually within a few seconds; The better the heat dissipation, the slower the reaction speed, usually around one minute.

　　The same device can operate with a time difference ranging from a few milliseconds to a few seconds under different conditions. But if the overload current of the circuit is dozens or even hundreds of times the normal working current of the circuit, the fuse will burn out before it can blow. Therefore, everyone should choose a fuse based on the actual circuit situation, so that the fuse can respond in a timely manner to protect the safety of the circuit.

　　There are two types of fuses: fast fuse and slow fuse. The two types of fuses have different blowing times, and you can choose the appropriate fuse based on the specific working situation of the product circuit. The response speed of a fuse is not fixed, it is determined by the devices that work together and the actual situation. For devices with millisecond level failures, it is necessary to understand whether it is a current or voltage failure, what the fault parameters are, and other performance requirements for protective devices. This way, you can know which model of fuse is the most suitable.
