Fuses are electrical devices that are installed in an electric circuit so as to interrupt the exceeding current by creating an open circuit condition. These are meant to protect the expensive appliances from being burnt out by voltage surges.

Fuse prevents electrical circuit damage and if not possible to totally prevent , it minimizes the level of damage by limiting it to lowest level that is possible.

A fusible link is connected between the fuse terminals, so that when the electrical current flowing through the fuse exceeds a predetermined limit, the link melts and open the circuit through the fuse to prevent electrical component damage. The blown off fuse link is then required to be replaced by a new one since fixing the old one is not possible.

Replacing a fuse doesn’t mean that you need to call an electrician, in fact you can yourself do the task without any much difficulty. Switching off the power supply is the first and foremost step that should be considered while replacing a fuse. Next, comes the task of removing the blown fuse and inserting the new one. While doing so, make sure that you are replacing it with that of similar rating.

In addition to this, never touch the metal parts while removing or inserting the fuse. Moreover, you should wear insulated gloves to be safe. Ensure, you do not try replace the fuse with wet hands.

If the fuse blows again before turning on any device, a serious wiring fault may exist. Call in a qualified electrician immediately.

Fuses protect electrical devices, components and circuits from over currents and short circuits. In addition to this, high reliability is one of the major advantage of using the fuse for over current protection. These are capable of limiting the overloads to only single circuit thus minimizing the danger of fire. Other benefits include circuit breaking and relatively low cost.

Fuses are employed in almost every electrical appliance so as to protect them against overload damages. Some very common areas of application of electrical fuse are motor bikes, ships and other vehicles. Moreover, fuses can provide for redundancy for the purpose of preventing reduction of yield of the semiconductor devices.
