020301.5HXG Application Field and Working Principle

Introduction to Fuses

Fuses are electrical safety devices that protect electrical circuits from over-currents and help prevent arcing faults, which can otherwise result in damage or fires. The most common type of fuse is the cartridge fuse, which consists of a metal tube or casing surrounding one or multiple metal brackets, an interrupting element, and other additional components. There are two basic types of fuses, time-delay and instantaneous. The differences between these types have to do with how quickly they react to over-current, and how the fuse operates especially during short-duration over-currents.

020301.5HXG Application Field and Working Principles

The 020301.5HXG, produced by the Zhejiang HXG Electrical Co., is a time-delay, midget, cartridge fuse which combines good electrical performance and safety features. It can be used in many different applications, such as circuit protection in household appliances, home theater equipment, computer equipment, and motor controllers.The 020301.5HXG features a ferritic iron core, a stainless-steel tube with integral contact pins, and a winding tin-plated seal strip, which ensures the integrity of the fuse’s internal components and protections against arcing faults. The core and contact pins are designed to prevent current surges, and to heat up properly if a fault occurs. The contact pins also provide an extra layer of safety in that they disconnect any disturbed current. When an over-current occurs, the heat generated by the core will be distributed to the external metal casing, thus delaying the time it takes for power to be interrupted. This helps to protect the circuit from damaging, as well as to prevent electrical arcs. The 020301.5HXG has a recommended operating temperature range of -55°C to 110°C , and can handle up to 13A of current. Additionally, the fuse is VDE, cULus, and TUV certified, providing additional assurances of safety. The 020301.5HXG is an ideal choice for circuit protection and reliably handles the current loads of modern, complex equipment. It combines adequate safety features and reliable performance, making it a popular choice for many user applications.
