The OLDC900.X series of electrical, specialty fuses provides protection for circuits and applications that require greater protection than what normal protection fuses can offer. This type of fuse features a unique construction, as well as special material combinations, which make it ideal for a wide variety of applications. In this article, we\'ll take a closer look at the application field and working principle of the OLDC900.X series of electrical, specialty fuses.

Application Field

The OLDC900.X series of fuses offers a wide range of protection for special applications such as fire alarm systems, electric arc furnaces, RFI/EMI filters, and many more. This fuse is specially designed to protect against short circuits, overloads, surges, and high inrush currents, and it’s designed for use with UL Class R, J, and CC rated circuit breakers. It has a maximum voltage rating of 280V and a maximum current rating of 30A. Additionally, this fuse is suitable for use with all standard North American voltages.

Working Principle

The working principle of the OLDC900.X series of electrical, specialty fuses is based on a combination of special material compositions and construction. The core of the fuse consists of a high resistance current sensing element that is housed within a protective terminal cover. This element is made of a special ceramic material, which ensures reliable protection over long periods in high temperature environments. When the current draw exceeds the rated value of the fuse, the element heats up and melts, thereby disconnecting the circuit and preventing over current conditions.

The fuse also features a special construction that allows for fast and reliable response in short circuit situations. This design feature ensures that the fuse will blow quickly in case of a fault and that the protection is reliable even in extreme temperature environments. Furthermore, the OLDC900.X series of fuses are specially designed to improve EMI/RFI filtering for the circuits and applications they are used on.

Conclusion

The OLDC900.X series of electrical, specialty fuses offer a wide range of protection and are suitable for a variety of applications including fire alarms, electric arc furnaces, EMI/RFI filters, and more. These fuses are constructed with a unique material combination and feature a special design that allows for fast and reliable protection in short circuit situations and high temperature environments. Furthermore, these fuses contribute to improved EMI/RFI filtering for the circuits and applications they are used on.
