You must have heard of the word fuse being used very commonly and you must be wondering how important is it? A Fuse is a device that is used to protect much more expensive electrical components from the damaging effect of overcurrent. The fuse consists of a low-resistance metal or wire that is used to close a circuit. Suppose too much current flows through the low resistant element of the fuse then the element melts and breaks the circuit.

We need to use a fuse because there are a few concerns that affect us. Our priority is always safe because we do not want any fire or accident to occur because of a silly mistake that is easily prevented. Sometimes we can be very careless and not investigate the cause of the fault when overcurrent devices trip. When a fuse opens it is replaced with a new fuse, in this way the protection level is not degraded by previous faults.

Fuses are also the most cost-effective means of protecting during overcurrent. Especially in situations where high fault currents exist or where small components such as control transformers need protection. Fuses have no part that could wear and tear, or become contaminated. So this makes it reliable. Fuses can also be coordinated so they can provide under both overload and short-circuit conditions.

The best thing about fuses is that as they get older they do not slow down or change. It does not affect its ability to protect with time. You might also think that fuses do not protect obsolete devices but the truth is that they can extend protection and upgrade themselves even to this kind of system.

Conclusion

If this little information has helped you understand the functioning of a fuse then you would know how important it is to have it installed at your house. They will extend their protection to all your electrical devices that you use at home.
