Q:What material is used for the fuse

Fuses must be easy to melt the wire, in order to fuse when the current is large, play a protective role, so usually lead-antimony alloy wire.

Q:The use and function of the fuse

Its role is when the circuit has too much current, the insurance produces more heat

Q:Why can not the electric faucet be used to reset the fuse automatically?

and is also likely to occur secondary dry. Some people may think that a high temperature, the fuse will automatically cut off the circuit, and then a temperature down, the fuse will automatically close the circuit

Q:When using low-voltage fuses, note that

fuse should be installed vertically to ensure that the socket and the knife holder in close contact,

Q:When selecting a fuse, you must consider several elements

That is, if the circuit voltage is 125V, then the choice of the rated voltage 125V and 250V fuse can be used. If the circuit voltage is 250V, it can only use 250V fuse, and can not use 125V fuse.

Q:Fuses should be repaired with the power distribution unit at the same time:

Maintenance Check the fuse, according to safety regulations, cut off the power, does not allow the removal of the fuse tube.

Q:Why copper can not replace the fuse

When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit or expensive devices, it is possible to burn the circuit or even cause a fire.If the circuit correctly placed the fuse ,

Q:Fuses can be divided into high-voltage fuses and low-voltage fuses.

According to the protection object can be divided into protection for the transformer and general electrical equipment with the fuse

Q:Why does the rated current of the fuse be based on the effective value as a standard?

The thermal effect of the conductor depends on the effective value of the current. So it is based on the effective value of the standard.

Q:What is a tube fuse

then inserted in the bearing or directly connected to the circuit
