![]() ![]() ![]() In normal conditions, the current passing through the fuse will also be normal. The main function of a fuse depends on the heat of the current passing through it. The current flowing in large quantities causes the wire to deteriorate quickly causing its lifespan to be shorter than regular. When a high amount of current is carried in this circuit, the wire attached to it softens and opens the circuit. It is always made of thin metal wire and the fuse in the circuit is always connected in series. The working principle of a fuse is based on the temperature of the current.

Here, the functional temperature of the fuse is high so that the current rating falls down. ![]() Here the voltage is connected in series with the fuse which does not allow the volume of voltage to increase. This can be measured in the value of ampere which is its thermal characteristics #2. Characteristics of Fuses:Ī few more features of the electric fuse are as follows:Ĭontinuing a higher amount of current that holds the device without melting is known as the current rating value. The length of the wire does not depend on the current rating, so the minimum length of the wire imposes a minimum value of resistance. This can usually be achieved by making the fuse wire length as short as possible. Many types of fuses are commonly used for circuit protection. If you have a home, office, or factory, you need a fuse instead. When the fuse breaks down or is damaged, the over-voltage can cause a glare in it which can damage the appliance in the house. We use fuses in homes so that no defects are created in the wiring of the house which protects against fire caused by a short circuit of wiring. The most direct and simple benefit of this is found in all our homes which protects the appliance in our house against overload current and short circuits.

This is the easiest and cheapest security device to use which protects us against short circuits and overloads. It is also known as an automatic disconnection system which is frequently shortened on ADS. The device is attached to a metal strip that melts when the current exceeds its set value.ĭue to the melting of this metal strip, the circuit opens and the current cannot proceed so any device attached to it cannot function. The fuse is an integral part of any circuit, whether electric or electronic and protects against overload current. ![]()
