0679H4000-05 Circuit Protection

Introduction to 0679H4000-05 Fuses

The 0679H4000-05 is a fuse designed to protect circuits and power sources from over-currents, thus optimizing the reliability of any system. It offers a wide range of applications, from the protection of household applications to the protection of machines and equipment in industrial environments.

Application Fields

The 0679H4000-05 is suitable for a variety of application fields. Its wide range of applications include, but are not limited to, the protection of switches, motors, light fixtures, household appliances, and computer equipment. It is also safe to use with AC and DC power sources. The 0679H4000-05 can be used in single and multiple fusing applications. Furthermore, it is a UL Recognized Component.

Working Principle

The 0679H4000-05 is designed to protect circuits and power sources from over-currents. It does this by acting as a thermal switch. When a current reaches a level that is potentially dangerous to the circuit, the 0679H4000-05 automatically shuts off the power supply. This thermal switch is a device composed of a conductive metal housed in a metal shell. It works by sensing heat and triggering a metal strip to expand (due to its thermal expansion coefficient). When the device is active, the metal strip expands inside the shell and triggers a switch that breaks the power supply.

It is important to note that the 0679H4000-05 has a low melting point and is usually sealed inside a resin-encapsulated body. This ensures that the heat produced internally won’t damage the surrounding equipment and circuits.

Conclusion

The 0679H4000-05 is a versatile fuse that can be used in a variety of application fields. It acts as a thermal switch, protecting circuits from over-currents by automatically shutting off the power supply. Moreover, it is a UL Recognized Component, ensuring a high degree of safety and reliability. With its wide range of applications and high degree of safety, the 0679H4000-05 is a great choice for any system.
