Q:What is a tube fuse

then inserted in the bearing or directly connected to the circuit

Q:Fuse according to the breaking current range can be divided into several

The breaking current range of the back-up fuse refers to a range from 4 to 7 times the rated current from the rated current to the maximum breaking current

Q:What is the difference between the breaking capacity of the fuse and the fusing capacity

Fuse characteristics of the fuse overload test, requiring the fuse in the overload test, the fuse fuse time to the standard within the range

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

All other breakers are represented by the rated current. Only a very small limit current switch may be expressed by the peak curren

Q:The use and function of the fuse

so that its temperature reaches the melting point, thus fusing

Q:Socket and fuse are connected to the zero line or FireWire

it will blow, cut off the power to protect the entire circuit safety, so the provisions of the fuse (or fuse) can only be installed On the line of fire, and the zero line is not allowed to install,

Q:What is the fuse often used?

the second part of the electrode, usually two, it is an important part of the melt and circuit connection, it must have Good conductivity, should not produce a significant installation of contact resistance

Q:The air switch is different from the fuse

Fast fuse fuse current is generally selected 1.5 to 2 times the load current, overcurrent 2 to 3 times can be quickly blown, and anti-time characteristics of steep, arc breaking ability, especially for power electronic device protection and DC circuit protection

Q:Quickly disconnect the fuse and cut off the fuse slowly

Reflecting the size of the impact current, more than the insurance rated current, the faster the fuse.

Q:Use a multimeter to check if the fuse is damaged

So the choice of fuse for the protection of lines and equipment, the first choice of the melt must be the size of the specifications, and then according to the melt to select the fuse
