Fuses: 0679L3500-05 Application Field and Working Principle

Fuses are an important part of an electrical system assisting in protecting people from hazards, equipment from damage, and the system from overloads. The 0679L3500-05 Carbon Fuse is intended for uses in low voltage DC and AC circuits, as well as data communication systems. It is designed for short-circuit protection while having the intrinsic advantage of self-resetting after the overload fault is cleared. The following sections will outline the application of the 0679L3500-05 and show its working principle.

Application Field

The 0679L3500-05 is used in low voltage systems such as those found in automobiles, home theatre systems, computers, electronics, and power supplies. This particular type of fuse is designed to protect against short-circuits that are caused when conductive elements come in contact with each other, accidentally or otherwise. It can also be used in the secondary protection system of both alternating current (AC) and direct current (DC) systems. Typically, this fuse is rated with a current of 3500A and a voltage of 0.05V.

The 0679L3500-05 is approved to be safe for use in hazardous areas. Such areas include, but are not limited to, dust particles, combustible vapors, and ignitable fibers. In addition to its safety rating, this fuse has a temperature rating of up to +125°C. This varied application and versatility make the 0679L3500-05 fuse the ideal choice for a variety of settings.

Working Principle

Fuses are typically composed of a metal conductor or wire housed in a ceramic body. In the 0679L3500-05, the wire is composed of a low temperature (105°C) carbon material. The composition of the fuse is of great importance since its type dictates the overall performance of the fuse.

The wire, or fuse element, is connected to the circuit\'s input and output nodes, meaning that the current will pass through the wire as it flows from one node to the other. This particular fuse has a rated current of 3500A, and so any current above this amount will cause the fuse element to heat up and eventually melt. When this happens, the circuit will be broken — which protects both personnel and equipment from any potential harm.

Once the fuse element has broken, it will need to be replaced. The 0679L3500-05, however, is a self-resetting fuse. This means that when the current returns to a safe level the device will become operational again. This saves time and cost, as the fuse does not need to be physically replaced every time it breaks.

Conclusion

The 0679L3500-05 Carbon Fuse is designed for protection against short-circuits in a low voltage environment. This device is safe to use, and is approved for hazardous areas such as those with combustible vapors or dust particles. The working principle of the device is based around its rated current — when the current exceeds this level, the fuse element will heat up and melt, breaking the circuit and protecting the surrounding environment. Lastly, the 0679L3500-05 benefits from a self-resetting feature so that there is no need to manually replace it each time.
