Fuseholders provide an easy and safe method to connect the fuse into an electrical system. The HM60600-3CR is a medium current fuseholder, designed to achieve a higher current rating in a compact size for use in various medium-power applications. This fuseholder offers reliable connection and protection for electrical systems. Through this article, we will explore the HM60600-3CR fuseholder application field and working principle.

1. Application Field

The HM60600-3CR is generally designed for medium-current applications, such as switching and protection of circuits in telecommunication networks, automation and engineering systems. It has the ability to be used as a single-phase or three-phase fuseholder, due to its wide range of compatibility for various types of current ratings. It is also suitable for outdoor or indoor installation in electrical distribution systems.

The HM60600-3CR includes two types of fuse-links, the HRC (high rupturing capacity) fuse and the HRC blade-type (gG) fuse. Depending on the type of application, the fuseholder provides a wide scope of applications, from low-voltage and low-current to high-voltage and high-current applications.

2. Working Principle

The working principle of the HM60600-3CR fusess depends on its type of fuse. An HRC fuse, which works on the principle of overcurrent protection, has internal heat dissipation elements that help reduce the flow of electrical current and prevents overloads, short-circuits, or damage to equipment.

When the current crosses the fuse-link rating, a small change in temperature occurs, resulting in the arc of the fuse turning off the current. An HRC blade-type (gG) fuse works similarly, using a blade-style fuse with an internal arc suppressor, which is a thermosetting material that helps to absorb any excess energy and prevent short-circuit damage.

Regardless of the type, the HM60600-3CR fuseholder includes a current rating of 2-25A, an AC voltage rating of 690V, and a DC voltage rating of 1000V. It has an IP20 degree of protection and a short-circuit current rating of up to 25kA at 690VAC.

Conclusion

The HM60600-3CR fuseholder offers a reliable connection and protection for electrical systems. It is suitable for both indoor and outdoor use and has various types of fuse-links for different applications. Designed for medium-current applications, it offers a wide range of current ratings and a high short-circuit rating. This medium-current fuseholder is equipped with a high-quality construction that makes it perfect for use with high-voltage and medium-power applications.
