Inrush Current Limiters (ICL)

The SL22 14007-A is a type of Inrush Current Limiter (ICL) that is designed to limit the inrush current surges in an electrical system. Inrush current is an undesired current surge that occurs when an electrical system is first powered on. ICLs like the SL22 14007-A are designed to protect an electrical system from the potentially damaging effects of inrush currents.

Principle of Operation

The SL22 14007-A ICL works by diverting the current surge during an inrush current event to a series of heaters, which resistively reduce the current before it is allowed to diverge back into the electrical system. The heaters are thermally-linked, meaning that they heat up and act as an additional resistance to decrease the current if it reaches high levels. This thermal overload protection also acts as a recommendation to prevent the heaters from short circuiting when an excessive current is present.

Applications

SL22 14007-A ICLs are designed to provide inrush current limiting in a variety of applications. They are commonly used in the electrical and electronics industries, as well as in consumer applications such as air conditioners, refrigerators, dishwashers, computers, and other residential and commercial appliances. Additionally, they are used in a variety of automotive applications, such as electric windows and motorized car doors. Finally, they are often used in hazardous location applications, where their ability to reduce inrush current surges can help to minimize the risk of electrical fires.

Benefits

The SL22 14007-A ICL offers several benefits over other types of inrush current limiters. First, it has the ability to limit inrush current at a wide range of currents, making it suitable for a variety of applications. Second, its heaters are thermally-linked, which provides additional protection from short circuiting and resistance to heat buildup. Third, it has a current rating of 22A, making it suitable for heavy load applications. Finally, it is UL certified, which ensures that it meets all safety standards and regulations.

Conclusion

The SL22 14007-A is an Inrush Current Limiting device that provides reliable protection from current surges. It offers a wide range of current limiting capabilities and has several benefits over alternative solutions, such as its thermal overload protection and UL certification. It is suitable for a variety of applications, including electrical and electronics, consumer appliances, and hazardous location applications.
