Fuses: 7100.1111.13 Application Field and Working Principle

A fuse is a type of safety device that is used to protect electrical circuits. It functions by quickly opening the electrical circuit when a predetermined amount of current is exceeded. The 7100.1111.13 fuse is a commonly used type of fuse, and it is frequently found in automotive and household electrical circuits. The following section will provide a description of the 7100.1111.13 fuse, including its application field and working principle.

Application Field

The 7100.1111.13 fuse is designed for use in automotive circuits only. It is suitable for use in low-voltage circuits where the maximum operating voltage is 14 volts. It does not provide the current capacity or the operating voltage required for use in higher power circuits such as those found in the engine compartment. Additionally, it is not designed to be used in electrical systems that operate at higher than 14 volts.

The 7100.1111.13 fuse is used most often in the front and rear lighting circuits of automobiles. It is also used in the audio and video systems of vehicles. This fuse is suitable for these applications because it can quickly disconnect the current as soon as it exceeds the predetermined value, thus preventing damage to the system.

Working Principle

To understand the working principle of the 7100.1111.13 fuse, it is first important to understand the composition of a fuse. A fuse consists of a thin wire that is heated and melted by the passage of current. The 7100.1111.13 fuse is composed of a copper wire that is wound around a ceramic former with a spring at either end. The spring is used to create tension on the wire, which prevents it from becoming damaged due to thermal expansion or contraction.

The 7100.1111.13 fuse is designed to allow a certain amount of current to pass through the wire. When more than the predetermined amount of current tries to pass through the wire, it causes the wire to heat up. This heat causes the wire to expand, which causes the spring at either end to compress and increase the tension on the wire. Once the tension becomes too much, the wire is heated to a point where it melts and breaks. This causes the circuit to be disconnected, thus preventing any further current from passing through the wire.

Conclusion

The 7100.1111.13 fuse is a type of safety device that is used to protect automotive and household electrical circuits. It is designed to disconnect the current as soon as the pre-determined amount of current is exceeded. The 7100.1111.13 fuse is composed of a copper wire that is wound around a ceramic former with a spring at either end. When more than the predetermined amount of current passes through the wire, the wire heats up and structurally fails. This causes the circuit to be disconnected, thus preventing any further current from passing through the wire.
