162.7049.4402

Fuses are electrical protection devices which are designed to disconnect a circuit in the event of an overcurrent such as an electrical short circuit or an overload. 162.7049.4402 is a type of fuse which is designed for use in industrial applications, and is capable of rapidly interrupting large currents with minimal energy loss. In this article, we will discuss the application field and working principle of 162.7049.4402 fuses.

Application Field

162.7049.4402 fuses are designed for use in industrial applications, and are particularly suited for protecting circuits which are used to deliver high currents, or circuits which are subjected to frequent start-up or shutdown operations. These fuses are also suitable for use in circuits which require frequent switching on and off, as their low internal resistance reduces the amount of inrush current, while the fast response time ensures that any overload or short circuit is quickly detected and the circuit is disconnected. 

Working Principle

The 162.7049.4402 fuse operates on the same principle as all other fuses, namely that of a fuse element which melts and opens the circuit if the current exceeds the maximum permissible value. In this case, the fuse element consists of a strip of copper which is fused between two terminals. The copper strip has a low resistance which allows large currents to flow through it, while the fuse element has a high melting point which ensures that it can interrupt high currents without being damaged.

When the current passing through the fuse exceeds the maximum permissible value, the heat generated causes the copper strip to melt, thus opening the circuit and disconnecting the power supply. The 162.7049.4402 fuse has a very low internal resistance, which minimises energy losses and allows for fast interruption of large currents. Additionally, the fuse element has a very fast response time, which ensures that any overload or short-circuit is quickly detected and the circuit is disconnected.

Conclusion

162.7049.4402 fuses are designed for use in industrial applications, and are particularly suited for protecting circuits which are used to deliver high currents, or circuits which are subjected to frequent start-up or shutdown operations. The fuse element is composed of a strip of copper fused between two terminals, and has a low internal resistance, fast response time, and high melting point which makes it capable of rapidly interrupting large currents with minimal energy loss.
