Introduction to Fuses

Fuses are electrical components that are designed to protect electrical circuits from damage due to excessive current. They have a fuse element, usually made of metal, that melts when too much current flows through it. Once the metal melts, the connection between the two terminals is broken, stopping the flow of current and preventing damage to the circuit.The type of fuse used in a particular application depends on its purpose, the type of environment it will be used in, the amount of current it needs to be capable of carrying, and the size of the fuse element. Fuses come in a variety of shapes and sizes, from the small blade fuses used in vehicle electrical systems to the large cartridge fuses used to protect industrial electrical systems.

7100.1164.95 Application Field and Working Principle

The 7100.1164.95 fuse is a Class ULU high rupture capacity (HRC) fuse designed for medium-voltage applications. This type of fuse is made from silver alloy strips with graphite powder, and it can be used to protect circuits with currents up to 63kA. This fuse is particularly suitable for distribution boards, transformers, switchgear, and air-conditioning systems. The working principle of this fuse is simple. When the current passing through the fuse exceeds its rated capacity, the temperature of the fuse element rises, causing the silver alloy strips to melt. This interrupts the current flow, protecting the circuit from damage. This type of fuse is also known as a thermal-magnetic fuse because it features both thermal and magnetic elements that are triggered when the current exceeds the fuse\'s rated capacity.The 7100.1164.95 fuse has an interrupting rating of 63kA at 230V AC, and it can be adapted for other voltage applications. It is UL/cUL listed, and meets the standards of IEC 60269.

Benefits of Class ULU HRC Fuses

Class ULU HRC fuses provide a number of advantages when compared to other types of fuses. The most important benefit is that these fuses are able to quickly interrupt high fault currents, protecting the circuit from damage. Additionally, these fuses are designed with an extremely low residual voltage, which helps to reduce the risk of fire from arcing. Another benefit of Class ULU HRC fuses is their reliability. These fuses are designed with a high-precision fuse element that is very dependable and reliable. This reduces the risk of the fuse failing to open under overload conditions, which would otherwise lead to circuit damage. Finally, these fuses are easy to install and require very little maintenance. They are easy to replace, and they can be fitted with other circuit protection components such as surge protectors or other protective devices.

Conclusion

The 7100.1164.95 fuse is a Class ULU HRC fuse designed for medium-voltage applications. This type of fuse is made from silver alloy strips with graphite powder, and it can be used to protect circuits with currents up to 63kA. It features both thermal and magnetic elements that are triggered when the current exceeds the fuse\'s rated capacity, interrupting the flow of current and protecting the circuit from damage. Class ULU HRC fuses provide a number of benefits, including their ability to quickly and reliably interrupt high fault currents, as well as their ease of installation and low maintenance requirements.
