Fuses are devices designed to protect the electrical circuits from an overload or short caused by excessive current. 5HFP 1 is an example of a single and dual power fuse that is widely used in high-voltage electrical circuits. It is composed of two ceramic elements that form the envelope and contain the fuse element. The 5HFP 1 has a rating of 1000 volts AC or DC and the dual power rating can go up to 1500 volts AC. The fuse element is made of ceramic material and consists of a coil of metal to create a magnetic field around it. This magnetic field is used to detect an excessive flow of current. In case of an overload, it will cause the fuse to blow and break the circuit.

5HFP 1 application fields are primarily used in high-voltage applications such as electric grid or industrial switchgear. It is used for protection against overload or short circuit and provides a high degree of safety and reliability. It can also be used in low-voltage applications such as motor drives, lifts, alarms, and security systems.

The working principle is based on the heat generated by the excessive flow of current. When the current rating exceeds the rating of the element, the heat causes the wire to break. This causes an increase in the air gap of the coil, generating a magnetic field around it. This magnetic field will interact with the contacts of the envelope and will cause the fuse element to break, breaking the circuit. By breaking the circuit, the 5HFP 1 fuse will protect the surrounding circuits from damage.

In conclusion, 5HFP 1 is a single and dual power fuse widely used in high-voltage electrical circuits. It is used for protection against overloads and short circuits, providing a high degree of safety and reliability. Its working principle is based on the heat generated by the excessive flow of current, which causes the wire to break and the contacts of the envelope to interact, thus breaking the circuit. With its reliability, 5HFP 1 is a valuable solution for protection of electrical circuits.
