Electrical Specialty Fuses are essential components to any electrical system, providing necessary protection from potential risks such as overvoltage, current overload, or short circuit. The 0090.1004 type fuse is a dual element fuse, designed to protect against both short circuit and overcurrent faults. In this article, we will discuss the 0090.1004 application field and working principle.

The 0090.1004 type fuse is a current-limiting type fuse, typically used in low voltage direct current (DC) applications. It is a single, compact unit, containing two independent blade-style fuses. It is designed for use in a wide variety of applications within the automotive and marine industries, from large scale industrial use to more specialized and localized needs, such as protecting the starter motor in a vehicle engine. The 0090.1004 fuse is designed to protect electrical circuits from both high current and short circuit faults.

Working Principle:

The 0090.1004 fuse operates based on a dual-element design. It consists of two primary components: a main fuse element, and a protection fuse element. The main fuse element is a cylindrical copper wire, wound around a cylindrical, non-magnetic core material. The protection fuse element, which is much smaller, is also composed of a cylindrical copper wire, wound around a non-magnetic core material. Both of these elements are connected in series within the fuse.

When a high current or short-circuit fault occurs, the current flowing through the main fuse element increases. This causes the core material to heat up and eventually melt. As this happens, the current is redirected and flows instead through the protection fuse element, which will also heat up and eventually melt. Once the protection fuse element melts, it removes the direct path for current flow, limiting its current to a safe level. This ensures the circuits and components downstream remain safe from damage. After the fault is removed, the fuse must be replaced.

Advantages:

The 0090.1004 fuse offers a number of advantages over other types of fuses. Firstly, it is specially designed for use in DC electrical circuits, meaning it offers greater protection for circuits and components. Secondly, it is compact, making it ideal for use in tight spaces or limited-space applications. Finally, its dual-element design provides added protection against both overcurrent and short circuit faults.

Conclusion:

The 0090.1004 fuse is an ideal solution for providing reliable protection against both overcurrent and short circuit faults in low voltage DC electrical systems. Its compact design and ability to limit current to safe levels make it an excellent choice for a wide variety of applications. It is important to note, however, that the fuse must be replaced once it has melted in order to ensure continued safety.
