Fuses 

The 5HF4 series is a low-temperature, fast-blow, general-purpose fuse. It is mainly used as the main protection of low-voltage switchgear and circuit breakers. In this article, we will look at the application fields and working principles of the 5HF 4 series.

Application Fields

The 5HF 4 series fuses are used in a variety of applications, including TV boards, circuit breakers, instrumentation products, control systems, motor starters, and more. It is also suitable for a wide range of voltages, from 6V to 660V. The fuses are strong in current loading capacity and can work for a long time without interruptions; moreover, they can protect electrical equipment from damage caused by short circuits or overloads.

Working Principles

In general, a fuse is made of an alloy or ceramic body, including a hard metal center surrounded by a coil of wire. When the current passing through the fuse exceeds the rated load, the metal center will heat up quickly, causing the coil of wire to melt and thus interrupting the flow of current. The temperature of 5HF4 series fuses is also very low, so it won\'t damage the equipment when the fuse trips. In addition, the fuse can be reset when the fault is cleared, and reused again.

The 5HF 4 series fuses are an essential part of any electrical system. They provide reliable protection against fault and overloads, while also offering long-term durability and reliability. With their low-temperature operation and excellent current loading capacity, they are sure to meet the needs of a variety of applications.
