045801.6DR Application Field and Working Principle

Fuses use a conductive path, in the form of a wire, to protect electrical devices from too much current or voltage. When the current or voltage exceeds a predetermined rating, the wire melts, cutting the power and preventing the device from being overloaded. Fuses have many common applications, including circuits in automotive and home wiring, power supplies, circuit breakers, and other electrical equipment.

The 045801.6DR fuses are mini-radial fuses with slow blow characteristics. They are UL listed and RoHS compliant and are designed with standard safety features to prevent shocks and fire incidents. The main advantage of 045801.6DR fuses is their high amp ratings, which can range from 5 amps to 40 amps, allowing them to provide adequate protection in cases with varying power requirements.

Working Principle

The 045801.6DR fuses have a bimetal strip construction that is used to control the melting temperature of the fuse. This construction is composed of two metal strips that are connected and placed between two conductive plates. The two metals have different thermal expansion coefficients which cause them to bend when heated up. When too much current flows through the fuse, the bimetal strip bends and touches the inside of the conductive plates, creating a path through which the current can further increase.

The increased current causes the metal strip to heat up to a point where it melts and breaks the connection, cutting the power. The temperature at which this happens is called the melting point, and is determined by the materials used and by the current that passes through the bimetal strip. This ensures that the fuse will be triggered and cut the power before the flow of current reaches dangerous levels.

Conclusion

The 045801.6DR fuse is a convenient and reliable choice for circuit protection due to its high amp ratings and UL listing. It is also RoHS compliant, making it an economically viable solution for many applications. Its bimetal strip construction allows it to rapidly respond to voltage and current fluctuations, cutting the power before it reaches dangerous levels.
