Fuses

Fuses are wire or strip devices that are designed to protect an electrical circuit from hazardous overloads or short circuits. Fuses come in a wide variety of connectors, sizes, and amperages to accommodate most electrical systems. The particular model of fuse that this paper discusses is the 0031.8557, which is typically used in household appliances, such as washing machines or refrigerators.

Application Field

The application field of the 0031.8557 fuse varies based on the amp rating, but it is typically used for low voltage applications, such as refrigerators, washing machines, and some lighting applications. This particular model is most often used in the protection of household appliances from overcurrent, and to help ensure the safety of citizens and properties by limiting the possibility and severity of electrical fires.

Working Principle

The 0031.8557 fuse works by using a bimetallic strip to detect any increase in current in an electrical circuit. As the current increases, the resistance of the bimetallic strip also increases, causing it to heat up. Once the resistance reaches a certain level, the heat causes the connection between the two strips to break and the fuse is "blown," effectively cutting power to the circuit and protecting it from further damage.

When a fuse is blown, the current no longer flows through the circuit, preventing further overcurrent that could cause damage to the circuit components. In order to reset the circuit, a new fuse can then be installed, and the circuit will be back up and running. It is important to note that the fuse must be properly rated for the circuit that it is protecting to ensure that it will perform properly.

Conclusion

The 0031.8557 fuse is a standard bimetallic fuse that is used extensively in low voltage applications. Its primary function is to protect circuits from overcurrent and reduce the possibility of electrical fires. It does this by breaking the connection between two strips of bimetallic material when the current reaches a certain limit, cutting off the power to the circuit and preventing any further damage. When the fuse is blown, it can be easily replaced with a new one rated for the same amperage and the circuit will be reset.
