0678H9400-02 Circuit Protection

Fuses

One of the most important components used in countless industries is the fuse. Fuses are devices used to protect circuits in the event of an overcurrent flow or inability of the circuit to handle excess current. Due to its safety and reliability, one such fuse is the 0678H9400-02. This article will cover the application fields and working principle of the 0678H9400-02 fuse.

Application Field

The 0678H9400-02 fuse has two main application areas. First, it is ideal for applications involving industrial buildings and electrical machinery, such as motor winding. Second, this fuse is often used as an overcurrent protective device in factories, commercial and aviation facilities. Its compact size and low current-carrying capacity makes it especially useful in these areas.

Working Principle

The 0678H9400-02 fuse is a thermosensitive device which has a bi-metallic strip construction. The construction consists of two pieces of metal, one of which is an electrically conductive strip and the other is a non-conductive strip. When a current passes through the fuse, the bi-metallic strip expands due to the heat produced. This expansion causes the non-conductive strip to push against the electrically conductive strip and break the circuit, thus preventing an overcurrent flow.

Advantages

The 0678H9400-02 fuse has several advantages. First, it is very reliable and safe; the bi-metallic strip will not break the circuit until it is heated to its maximum safety rating, ensuring it will always provide the necessary protection. Second, it is extremely cost-effective; the components used in the construction of the fuse are very affordable and it is also able to handle low-current loads, making it ideal for industrial applications. Finally, this fuse is highly durable and can last for extended periods of time.

Conclusion

The 0678H9400-02 fuse is one of the most reliable and cost-effective fuses available. Its application field includes industrial buildings, electrical machinery, and overcurrent protection. Its working principle is based on a bi-metallic strip construction which breaks the circuit when it is heated to its maximum safety rating. The advantages of using this fuse include its reliability, cost-effectiveness, and durability. This makes the 0678H9400-02 one of the most popular fuses for industrial applications.
