FWP-900

Fuses are a vital part of an electrical system, as they help to protect valuable equipment from short circuits, overcurrent, and other damaging issues. The FWP-900 Specialty Fuse is designed specifically to provide protection against these problems in applications ranging from domestic to industrial scale. In this article, we will take a detailed look at the FWP-900 application field and working principle.

What is the FWP-900?

The FWP-900 is a thermal-magnetic fuse that has been designed for protection against overcurrent, short circuits, and overvoltage in residential, commercial, and light industrial applications. It is fully compliant with IEC 61558-2-12, UL 566, and CSA standards.

Features of the FWP-900

The FWP-900 has a number of important features that make it an ideal choice for protecting both domestic and industrial electrical systems. It features a thermal overload protection system, which trips at 125% to 140% of its rated current, and includes a melting element that is designed to react to overloads and short circuits, providing effective short circuit protection, while also allowing the fuse to reset after the overload has been cleared.

The FWP-900 also features an additional thermomagnetic trip setting that ensures the fuse will trip if overloaded, or if the system voltage goes above or below the preset level. This ensures that your equipment is properly protected against overvoltage, and that your system is able to reset itself after an overload or short circuit.

Applications of the FWP-900

The FWP-900 can be used in a variety of applications, both domestic and industrial. It can be used in residential and commercial switchboards, in light industrial applications such as machinery, elevators, pumps, compressors, and other similar applications. Additionally, the FWP-900 is compliant with UL, CSA, and VDE standards, meaning it can be installed in any application where these standards are in place.

Working principle of the FWP-900

The FWP-900 operates on the principle of an electric arc; when the fuse reaches a certain temperature, an electric arc is initiated, which interrupts the flow of electricity. This ensures that any overcurrent or short circuit is immediately cleared. The thermomagnetic trip mechanism of the FWP-900 also overcomes the traditional fuse limitation of resetting after a short circuit, as it is able to react to the overvoltage and trip the fuse.

The FWP-900 also has a ‘break-before-make’ feature, which prevents sparks when switching the fuse on or off. This is essential as it prevents any damage to the fuse itself, and any equipment connected to it.

Conclusion

The FWP-900 Specialty Fuse is designed to provide reliable protection in domestic, commercial, and light industrial applications. It combines thermal overload and thermomagnetic trip settings to provide reliable overcurrent, short circuit, and overvoltage protection, while also providing the ability to reset after an overload or short circuit has been cleared.

Overall, the FWP-900 is an ideal choice for protecting electric systems in both domestic and industrial settings, providing reliable protection against the elements.
