17.5OHGMA40

17.5OHGMA40 is a type of electrical specialty fuse popularly used in many applications. This type of fuse is usually used with medium voltage transformers, but can also be found in other high voltage electrical equipment. This article will explain the application field and working principle of 17.5OHGMA40.

17.5OHGMA40 has a wide application field. Low control current, low prevention limit and excellent quality of insulation make it suitable for use with medium voltage transformers. The 17.5OHGMA40 fuse is also commonly used in high voltage motors, cables, capacitors, alternators, inverters, and other high voltage electrical systems.

The working principle of a 17.5OHGMA40 fuse is simple yet very effective. This type of fuse operates on a principle of melting when the current it experiences reaches a certain limit. When it reaches this point, the melting point of the metal contained in the fuse, the fuse will be triggered and the power will be cut off.

The melting point of the fuse is determined by the type of metal incorporated in it. This type of fuse is made from an alloy called molybdenum, which has a melting point of 1750°C. When it encounters a current surge, the metal will melt instantly, breaking the circuit as quickly as possible.

The design also carries other features. The 17.5OHGMA40 fuse uses a radial structure, where the metal contents of the fuse are arranged in a radial pattern around the center of the fuse. This structure makes it much more effective at restricting the current it experiences, as the current is divided and distributed evenly along the fuse.

Overall, the 17.5OHGMA40 fuse is an effective and reliable solution for controlling large amounts of electrical power. The combination of the molybdenum alloy and radial fuse design makes it a great choice for low current and high voltage applications.  The casing for the fuse also features improved insulation which makes it more reliable in comparison to other fuse types.

This article has discussed the application field and working principle of the 17.5OHGMA40 fuse. It is an effective fuse for use in medium voltage transformers and other high voltage applications. The metal alloy it contains melts quickly when the current reaches a high limit, and the radial structure increases the effectiveness of the fuse.
