SST 3.5/5K

Introduction

Fuses are an important component in the electrical industry, used to protect electrical circuits. In this article, we will discuss the application field and working principle of SST 3.5/5K fuses.

Application Field

SST 3.5/5K fuses are mainly used to protect AC motors. SST 3.5/5K fuses can provide reliable over-current protection in a wide range of industrial and commercial applications, such as computers, printers, bar code scanners, pumps, motors, and other high power equipment.

Working Principle of SST 3.5/5K Fuses

The main components of SST 3.5/5K fuses are quality copper alloyed fuse clips which can securely hold the fuse against the fuse carrier. Additionally, the cable ties are fitted to the fuse clips to provide additional support and ensure the fuse is securely fixed in place after installation.

When an over current occurs, the fuse wire will melt in proportion to the current, forming a ‘short-circuit’ which will cause the fuses to open and break the circuit. As a result, the current flow in the circuit will be limited to the rated value of the fuse, thus protecting the circuit from the over-current. The overload protection time can be adjusted to suit different applications.

Conclusion

To conclude, SST 3.5/5K fuses are mainly used for AC motor protection. Their working principle is based on the melting of the fuse wire due to the high current which will limit the current in the circuit. This helps ensure the safety of the electrical circuit.
