INTRODUCTION OF FUSES

Fuses are the simplest protective electrical appliances, which are used to protect electrical equipment from damage from overload and short-circuit current; choose different types of high-voltage fuses according to installation conditions and uses, such as outdoor drop type, indoor type, and high-voltage fuse for some special equipment. The fuse should be a special series; the fuses we often say are fuses.

Types of high voltage fuses

1. British standard fuse

British fuses are mainly used in equipment produced in the Commonwealth of Nations. The British standard fuse shell is made of ceramic material. The product has the characteristics of small size and high cost performance, and is especially favored by UPS manufacturers below 240V.

2. American standard fuse

American fuses are the most widely used, covering most power electronic product applications. The American Standard fuse shell is made of melamine mesh cloth and ceramic lamination process, which has strong impact resistance, and has the characteristics of small Joule integral value, low power loss, and excellent DC performance. It is widely used in substations, electric locomotives and other occasions.

3. European standard fuse

The European standard square fuse shell is made of ceramic material. This product has the characteristics of low operating temperature, low power loss, and small Joule integral value. It is suitable for applications requiring compact structure, superior performance and high power, especially in manual maintenance switches (MSD ) are used extensively.

4. French standard fuse

French standard fuses have the characteristics of strong cycle performance, small size and unique structure, and are suitable for small UPS, small AC drives and other low-power applications with small footprint.
