Fuseholders

03455QS8H Application Field and Working Principle

A fuseholder, also known as a fuse box, is an electrical device designed to protect circuits from damage or destruction due to over current or short circuit conditions. A 03455QS8H fuseholder is specifically designed for use with the 03455QS8H fuse, which is a high performance general-purpose fuse with a time-delay feature designed to protect motors and main circuits from overload damage. The 03455QS8H is a blade-type fuse capable of current ratings from 0.2 amp to 30 amp, with a voltage rating of up to 800 volts AC.

Application Field

The 03455QS8H fuseholders are suitable for use in branch, lighting, and motor control circuits. They are suitable for applications in residential, industrial, and commercial settings, such as in machine tools, vehicle manufacturing, mining, data processing, and telecommunications.

Working Principle

The 03455QS8H fuseholders are designed to protect circuits from damage due to over current and short circuit conditions. The fuse clip inside the fuseholder holds the fuse in place and allows it to blow in the event of an overload or short circuit. The fuseholder also provides electrical isolation between the circuit and the fuse, reducing the risk of electrical shock. The 03455QS8H fuseholders feature a common terminal design that simplifies installation and maintenance. The blade-style fuse clips provide a secure grip delivering fast and efficient insertion and removal. The fuse indicator allows the user to determine the fuse status at a glance.When the current exceeds the rated value, the fuse melts to open the circuit, cutting off electric current, and protecting the circuit. When the fault is cleared, the fuse will need to be replaced before the circuit can be restored.

Safety

The 03455QS8H fuseholders feature safety features such as UL approved insulation, replaceability, and also provide electrical isolation between the circuit and the fuse. Additionally, the fuse indicator allows the user to easily determine the status of the fuse without the need to open the fuseholder.

Conclusion

The 03455QS8H fuseholders are designed specifically for use with the 03455QS8H fuse, and feature a secure blade-style clip for reliable performance. The fuseholders offer a reliable, safe, and effective solution to protecting circuits from damage or destruction due to over current and short circuit conditions. Additionally, the UL approved insulation, replaceability and indication feature provide additional safety benefits.
