39515000440 Application Field and Working Principle

Fuses are electrical wires used in electrical circuits in order to protect them from damage or overheating caused by excessive current. They are a relatively inexpensive way to protect circuits from being damaged, and they are available in a wide range of sizes and specifications. Fused wire is usually made from copper wires, but it can also be made from aluminum, titanium, or other materials. The fuse wire is designed to melt in the event of a short circuit or overload, breaking the electric circuit and preventing further damage to the equipment.

39515000440 Application Field

39515000440 type of fuses are widely used in the vehicle, electronic circuit, thermal protection and other fields,and it is suitable for ordinary circuits and overload and short circuit, also for ac 50Hz/60Hz and a voltage of 400v;ac circuits such as lighting is suitable when the current is not more than the maximum limit within the current time.

39515000440 Working Principle

The working principle of the 39515000440 type of fuse is quite simple. The fuse wire actually contains a pre-measured amount of metal which is melted by the heat generated due to excessive current in the circuit. As the fuse wire heat up, the metal melts, and this causes the circuit to be broken and prevent any further damage. The amount of metal that is present in the fuse wire is chosen to be just enough to allow the normal current flow in the circuit, but not enough for it to melt during a short circuit or an excessive current flow.

These fuses are designed to be quick-acting, meaning that they will react quickly to an overload or a short circuit, before any extensive damage can occur. This is one of the main reasons why they are so commonly used in many different applications.

Conclusion

39515000440 type of fuses are designed to protect circuits from excessive current that can cause damage or overheating, as well as from short circuits. They are relatively inexpensive, and they are available in a wide range of sizes and specifications. This type of fuses work by melting a pre-measured amount of metal inside it in the event of a short circuit or overload, breaking the electric circuit and preventing further damage to the equipment.
