0679H3000-01 Circuit Protection

0679H3000-01 application field and working principle

The 0679H3000-01 is a fast-acting class of fuses used for protection of electrical circuits. It works to provide protection from circuit overloads that occur when too much current is flowing through the circuit. When an overcurrent situation occurs, the fuse element will melt, cutting off power to the circuit and possibly preventing it from catching fire.

The 0679H3000-01 is designed for use in a variety of applications requiring moderate overload protection, including small motors, household appliances, power tools, and automotive applications. It is suitable for use as both primary and secondary protection in medium voltage control circuits. Its physical size and shape is such that it can fit easily into junction boxes and panels that require low profile components.

Working Principle

Fuses work through a principle known as the thermal-magnetic characteristic. In an overloaded circuit, the amount of current flowing through the circuit increases, resulting in an increase of heat energy. This heat energy is dissipated through the pole pieces, which are responsible for containing and dispersing the thermal energy. As the heat energy increases, the resistance of the circuit drops, thereby allowing more current to flow through the circuit.

As the heat energy continues to increase, the copper coils in the fuse will begin to heat up and reach the melting point of the wire. This will cause the wire to melt, thus cutting off the supply of power to the circuit. In other words, the wire melts and the circuit is protected from overcurrents.

Features and Benefits

The 0679H3000-01 is a UL rated, 600V, Class CC fuse that offers a number of benefits to the user. It features a unique design that helps to prevent arcing, making it safer for the user and the environment. It is compact in size and is able to fit in tight areas, as well as enclosures with limited space. The fuse is extremely reliable and has a quick response time and high interrupting capacity.

The 0679H3000-01 also offers superior electrical performance, with low emissions and minimal voltage loss. It is designed to withstand thermal cycling and provides additional protection against shocks and surges. In addition, the fuse has a high breaking capacity and an excellent dielectric strength.

Overall, the 0679H3000-01 is an excellent option for providing protection from circuit overloads. Its wide range of benefits makes it an ideal choice for a variety of applications.
