Introduction

PTC Resettable Fuses are used as overcurrent protection elements in circuit designs. They are available in a variety of different models, including the 24LT100U PTC Resettable Fuse. This fuse has a wide range of application fields and a unique working principle.

Application Fields

The 24LT100U PTC Resettable Fuse is designed for multiple applications. For example, it is suitable for use in automotive systems such as vehicles and trucks. In the automotive sector, the 24LT100U PTC Resettable Fuse can be used for short circuit protection, overload protection, and damaged battery isolation.The 24LT100U PTC Resettable Fuse is also an excellent choice for protection of electronic devices such as telephone lines, computers, and other general purpose electronic circuits. It can be used in both AC and DC systems, making it a versatile solution for an array of applications.

Working Principle

Unlike traditional fuses, PTC Resettable Fuses do not require replacement when they trip. The 24LT100U PTC Resettable Fuse works in a unique way. When the current running through the fuse reaches the rated current limit, it rises and activates a bimetallic element that is integrated into the fuse structure. This bimetallic element triggers a rapid thermal expansion which generates an internal resistance and cuts off the current running through the fuse. This rapid thermal expansion is known as a "trip current".Once the current is cut off, the bimetallic element cools and returns to its original position, resetting the fuse in the process. This process is then repeated when the current reaches the rated limit again, providing an effective way of protecting circuit components from current surges and overloads.

Conclusion

The 24LT100U PTC Resettable Fuse is a reliable protection element that can be used in a variety of applications, from automotive systems to electronic systems. It has a unique working principle which utilizes a bimetallic element to rapidly thermal expand and cut off the current running through it. This process then repeats for protection against current surges and overloads.
