Introduction

Fuses are devices that protect electric circuits from sudden excesses of current, such as short-circuits and overloads, that could cause damage or a fire. Fuses inherently contain a small piece of metal that melts when electric current passes through a certain value. In case of SSQ 630/1K fuses, the theory and application field remains the same. It is a slow-blow GPV PCB Mount Fuse which can be used in a wide variety of electronic and electrical circuits across multiple industries.

Function and Working Principle

The SSQ 630/1K Fuse is a one-time-use, non-resettable blown element device. At temperatures up to 1K Celsius, the fuse\'s element is designed to melt after a certain amount of time has passed and after the current has exceeded a specified value. The protection is provided by the SSQ 630/1K Fuse when the current flows through the fuse, the element conducts the current. If the current exceeds the particular value, then the element starts encountering the resistance causing joule heating. This heat starts to increase rapidly and reaches the melting point of the element usually around 1K Celsius which gets melts. In this way, the circuit gets disconnect due to opening of the current due to melting of the fuse.

Application Field and Installation

The SSQ 630/1K Fuse is most commonly used in the electrical, automotive, and other industries where circuit protection is needed. Typical applications include computers, audio and video equipment, power supply units, and power amplifiers. Due to its small size and light weight, it makes it ideal for use in portable devices. The SSQ 630/1K Fuse is very easy to install and use as long as the instructions provided are followed correctly. Some general instructions include ensuring that the voltage and current ratings of the SSQ 630/1K Fuse match the ratings of the circuit being protected, and that it is installed in line with the circuit being protected, so as not to cause any damage.

Conclusion

The SSQ 630/1K 100mA Slow-Blow GPV PCB Mount Fuse is an effective tool in protecting electric circuits from sudden excesses of current. With its small size and light weight, it makes it easy to use in a wide variety of applications. Its thermal-magnetic element is designed to melt after a certain amount of current is exceeded and the protection of the circuit is maintained. Additionally, it is easy to install and use, making it a go-to choice for many users.
