This is because the internals of a circuit breaker does not get destroyed in the event of an overcurrent. Circuit breakers are used in certain applications instead of fuses as when they trip you can simply reset them without replacing them.
They are a cost-effective way of providing electrical protection to electrical systems. If fuses were not fitted the excess current could melt cable insulation and potentially damage other components within the circuit.įuses are used in nearly all electrical devices and circuits. Overcurrent can be caused within an electrical circuit by short circuits, electrical arcing, and similar electrical issues. They have an outer sheath that is used as a safety device to minimise arcing in the event of a severe overcurrent. The point at which a fuse will blow its conductive strip is called its breaking capacity. When the fuse blows it opens the electrical circuit and stops any current flow through the connected circuit or components.

A fuse is always fitted in series with the circuit/components that need protection from overcurrent. Fuses reduce the risk of electrocution and fire, they also protect wiring and components and minimise the amount of heat damage that could be caused. If the conductive strip melts within a fuse the circuit will break and prevent any current from flowing through. They are internally filled with a conductive strip that melts in the event of an excessive current passing through. What is a fuse?Ī fuse is a device built for the safety and protection of a circuit. In this article, we will start by looking at what a fuse actually is, we will look at the different types of fuses and their applications, and finally, we will answer some key questions associated with fuses. Knowing what a fuse actually is and what it does is a completely different matter. Generally, people know that from time to time a fuse may need replacing and can be one of the reasons why your electrical device may not power on. You have more than likely heard the term fuse mentioned when referring to any electrical device or circuit.
