0225.100H

Fuses are electrical devices that are used to protect electrical circuits from damage from overload events. They act as a final line of defense to protect other components in a circuit from becoming damaged due to excessive current or voltage. The 0225.100H fuse is a type of fuse specifically designed to protect medium voltage electrical distribution systems from overcurrents. Its application field and working principle are discussed in this article.

Application Field

The 0225.100H fuse is recommended for use in secondary distribution up to 18kV systems. It can be used as a main or branch fuse in both indoor and outdoor applications. The 0225.100H fuse is rated for up to 100A of continuous current and interruption current ratings up to one-third of the nominal load current. It can handle extreme weather conditions, such as temperatures ranging from -40F up to 185F. It is UL listed for vertical or horizontal mounting and can be used with shielded adapters in the presence of strong magnetic fields.

Working Principle

The 0225.100H fuse works on the same basic principle as all other types of fuses. It is a wire with a very low melting point, which is designed to melt when an excessive amount of current is present in the circuit. When the melting point is reached, the wire will break the connection with the circuit, protecting all other components from dangerous overloads.

The operation of the 0225.100H fuse is made possible through the use of a special type of conductor called a ferrule. The ferrule is a small cylinder of metal that is inserted into the fuse. This ferrule acts as a resistor, which limits the flow of current in the circuit. As more current flows through the circuit, the ferrule increases its resistance, which in turn causes the fuse to heat up. If the current reaches a certain threshold, the fuse will reach its meling point and break the current flow in the circuit.

Conclusion

The 0225.100H fuse is designed to protect medium voltage electrical distribution systems from overcurrents. Its application field and working principle make it suitable for both indoor and outdoor use in secondary distribution systems. The fuse employs a ferrule and a wire with a low melting point to break the current flow when an overload is present, thus protecting other components in the circuit.
