0326.400H Fuses

A 0326.400H fuse is a type of fuse that is designed to protect against overcurrent in electrical circuits. It has two types: time-delay and fast-acting. The fuse is designed to protect the circuit from more than 10 times the rated current and should not be used for more than the normal anticipated loading.

Construction

At its core, the 0326.400H fuse consists of a fusible metal strip between two end connections. It also features a tamper-proof unit that encloses the metal strip. The strip is made of a conductive material, such as copper, and can withstand current up to 10 times the rated current.

Application Field

The 0326.400H fuse is mainly used in low voltage electrical circuits, such as those in residential and commercial buildings. It is also suitable for applications in electrical motor control, such as motor starters and contactors. The fuse also finds application in various industrial settings, such as in process plants, electrical power tools, and lighting.

Working Principle

The working principle of this type of fuses is based on the melting of the fusible metal strip due to the presence of an excessive electric current. When the current flow surpasses the specific rating of the fuse, the fusible metal strip starts to melt down and breaks the electric circuit, thus preventing potential damages due to electrical overload.

Advantages

The 0326.400H fuse is a reliable and safe choice for overcurrent protection. It is highly precise and can easily detect any overload in the system’s current. This type of fuse is relatively inexpensive and easy to install and replace. It provides maximum protection against overcurrent without interfering with the current flow, and it also has a compact and durable design.

Disadvantages

One of the main disadvantages of this type of fuse is its inability to automatically reset after a short circuit has been detected and removed. This requires manual intervention, which means the circuit has to be fixed manually before it can be used again. Additionally, the 0326.400H fuse is only suitable for applications up to 10 times the rated current and cannot be used for applications that require more.

Conclusion

The 0326.400H fuse is a type of fuse designed to provide reliable overcurrent protection in low voltage circuits. It features a tamper-proof unit and a highly precise fusible metal strip that can easily detect overloads of up to 10 times the rated current. The fuse is relatively inexpensive, easy to install and replace, and has a compact and durable design. However, it cannot be used for applications with higher current ratings, and cannot reset automatically after a short circuit has been detected and removed.
