Q:What is the factor of the fuse tube?

Safety certification of fuses and their requirements

Q:What parts are the fuses divided

The melt is the main working part of the fuse. The melt is equivalent to a special wire connected in series in the circuit. When the circuit is short-circuited or overloaded

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

the other hand, the use of slow blow fuse where the use of fast-blow fuse , It will often cause the boot that fuse can not work properly.

Q:What is the difference between fuses and fuses?

Made a plug-in shape of a component, its internal core is the fuse.

Q:Fuses are generally not overloaded.

Short-circuit protection refers to the ability to quickly cut off the load circuit at high currents.

Q:The difference between DC fuses and AC fuses

thanks to the rapid melting of the fuse and the diffusion of quartz sand adsorption and cooling forced to extinguish the arc, so it is much more difficult than breaking the AC

Q:What is an open fuse

supported by the porcelain column, no bearing, suitable for low pressure outdoor use.

Q:What is the working principle of the fuse

Fuses are widely used in low-voltage distribution systems and control systems and electrical equipmen

Q:What should you pay attention to when using high voltage fuses?

check the outdoor fuse installation angle changes, points, closing operation should be flexible ; Melt fuse when the fuse tube should be fast, can form a clear isolation gap.

Q:The fuse is to prevent the circuit

The fuse is in series in the circuit, and its resistance is slightly larger than the wire, once the circuit has a short circuit,
