A fuse tube apply is also called a fuse, and a fuse is also known as a fuse, which is defined as a “fuse” in IEC 127. It is an electrical component installed in the circuit to ensure the safe operation of the circuit. The role of the fuse is: when a circuit failure or abnormality occurs, accompanied by rising current, and the rising current may damage some important devices or valuable devices in the circuit or may burn the circuit or even cause a fire. If the circuit is correctly placed in the fuse, then the fuse will blow itself to cut off the current when the current rises abnormally to a certain height and certain time, thus playing a role in protecting the safe operation of the circuit.
Fuse Role
The role of the Fuse tube apply is
1. Under normal circumstances, the fuse plays a role in the circuit to connect the circuit.
2. non-normal (overload) conditions, the fuse as a safety protection element in the circuit, through its own fuse safety cut off and protect the circuit.
The effect of fuse aging on the use
After the fuse aging, it will not produce the current should be cut off and the fuse does not blow the danger. The fuse aging is equivalent to a decrease in the rated value (current) rather than an increase, so it will not cause safety problems in the circuit, but will cut the circuit at a small overload current or pulse
