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:The choice of fuse tube can be based on the following process

the ambient temperature on the impact of the carrying capacity of the fuse tube, see "ambient temperature".

Q:What does the fuse HRC say?

while limiting the current through the current to less than the peak current.

Q:What is a spiral fuse:

which is commonly used in machine electrical control equipment.

Q:Why the neutral line can not fuse

In the industrial electricity (380V), three-phase air switch (than the anti-over-current role of the fuse, but also more)

Q:Fuse letter of the fuse

GL (DIN VDE) / gG (IEC) full range of cable and wire protection

Q:The main parameters of the fuse selection

Usually in the DC circuit, using 10 times the rated current as the fault current, so that the fuse in a very short period of time off, through high-speed oscilloscope

Q:Fuse tube selection fuse factor

Ambient temperature or known operating temperature has a direct effect on the operation of the fuse. The higher the ambient temperature, the farther the fuse at work, the shorter the life expectancy.

Q:What is a tube fuse

then inserted in the bearing or directly connected to the circuit

Q:Are there any resistance to the fuse?

The fuse has a resistance value, in fact, even the wire also has resistance, but the resistance of the wire is very small (the nature of the conductor), in the general circuit calculation, we usually do not count
