7043.8210 Datasheet/PDFFuses: 7043.8210 Application Field and Working Principle
Fuses are indispensable components in many electric circuits and their application should not be underestimated. In this article, we’ll introduce a very special type of fuse, 7043.8210, and discuss its application field and working principle.
Application Field
7043.8210 type fuses are mainly used in electric power distribution boards, switch boxes, and household appliances, in which it provides complete protection against overload or short-circuit currents. They are mainly made of Cooper and work in temperatures below 85℃. Its rated current can last 2kA and also can endure 6kA for a certain period of time. What’s more, its rated current can be adjusted depending on the requirements of clients.
Working Principle
As previously mentioned, fuses are made from Cooper and designed to protect against electrical overloads and short-circuits, and the working principle of 7043.8210 type fuses is no different. It utilizes the ability of Cooper to resist electric current through it - known as resistance, and when the current passes through the fuse is greater than the rated current for a very short period of time, then the Cooper melts, foaming and rupturing. As a result of this quick reaction, the circuit will be disconnected, thus protecting the rest of the system from further damage.
This melting ability also depends on the temperature and material of the Cooper. In the case of 7043.8210 fuses, its Cooper is robust and can resist temperature upto 85℃, making it perfect for power distribution boards and other switch boxes.
Conclusion
7043.8210 type fuses are an important component in electric circuit, and they can provide complete protection against overload and short-circuit. As discussed in this article, they are made of Cooper and have a resistance to electric current, meaning that when the current is greater than the rated current for a short period of time, the Cooper melts and protecting the system from further damage. Furthermore, they are specifically designed to work in temperatures below 85℃, which makes it ideal for power distribution boards, switch boxes, and household appliances.
