Fuses

Fuses are an important safety component used in many electrical and electronic circuits. They protect against the risk of overcurrents, and they act as an emergency shut-off switch in the event of electrical fires. The 7100.1159.13 is a type of fuse widely used in industrial, automotive, and aerospace applications. In this article, we will discuss the application field and working principle of this fuse.

Application Field

The 7100.1159.13 fuse is designed for use in electrical circuits with rating 42VDC/15.07A, with a temperature range of -25 °C to +125 °C. It is is suitable for use in a range of applications, including process control, automotive, telecoms, and domestic electrical wiring. This fuse is available in several different form factors, including blade, square, and screw. It also comes with a variety of terminal configurations, including blade, pin, and plug. As a result, this fuse can be used to protect a wide range of electrical systems and devices.

Working Principle

The 7100.1159.13 is an electronic fuse, meaning it is an integrated circuit (IC) with a temperature-sensitive semiconductor element, often composed of silicon. This semiconductor element is designed to be thermally sensitive, meaning it will "trip" or open the circuit when it reaches a certain temperature, rupturing the internal resistor (Ri). This will in turn cause the current to drop, stopping any further current flow and protecting the circuit.

The 7100.1159.13 also features a built-in high temperature shut-off, which will shut down the entire circuit in the event of an overcurrent situation, further protecting the components and circuit. This shut-off is designed to be fast-acting, so your equipment will be protected without delay.

Conclusion

The 7100.1159.13 is a versatile and reliable electronic fuse, suitable for use in a range of applications. It has a wide temperature range, making it a great choice for industrial, automotive, and aerospace circuit protection. Its built-in thermal element and high temperature shut-off ensure that it will effectively protect the circuit in the event of a fire, keeping your equipment safe from overcurrents.
