Fuse
is an electrical device that is used to protect the circuit from
overload and overcharge. During the over current or overload , the
fuse , which has low resistance, melts and protects the main circuit
, by disconnecting the power supply from the man source . The low
resistance wire melts when high current passes through it.
Types
of fuses –
DC
and AC fuses – the difference between these two fuses is not much.
The only difference is that AC fuses are used in the AC systems and
DC fuses are used in the DC systems. In the DC system, when low
resistance wire melts, an arc is created, which is difficult to
extinguish because of constant electricity in direct current. To keep
the arc minimum, the direct current fuse is bit longer than alternate
current. This bigger size of the direct current Electrical BPLKits Manufacturer
fuses increase the distance between electrodes, which reduce the size
of the arc.
The
alternate current fluctuates, so it is easy to curb the arc in the
system. Therefore the size of alternate current is smaller than
direct current.
One
time use fuse –
One
time fuse are the metallic wire fuse, which burns when current
overflow through them. After the melting, the fuse is manually
replaced. This type of fuses is cheap and used in most of the
electrical and electronic systems. The one time fuse is categories on
the following bases.
These
bases are breaking capacity of the fuse, current carrying capacity
of the fuse, packaging size and response characteristic, related
voltage of fuse etc.
Cartridges
fuses ---
These
fuses are used in high voltage and current ratings system. They are
used in motors, air conditioners, pumps, refrigerators etc. They use
mostly occurs in industrial and commercial places.
Again
the cartridge fuses can be divided into types. One is general purpose
fuse and other is heavy duty cartridge fuses. General purpose fuse
comes with no time delay and heavy duty has time delay.
Blade
fuse type –this fuse is also called plug in fuse or spade fuse.
They come in plastic body with two metal caps to fit the socket.
These are used in automobiles for short circuit protection and
wiring.
The
main use of fuses is Drop Out Fuse Set Manufacturers to
protect the circuit from the main source of electricity in the real
time scenarios. The fuse protects users from extensive damage that
may happen from overflowing currents.
