Introduction

Inrush Current Limiters (ICL), such as B57238S0220M051, are essential components in a wide variety of electrical applications. They limit the amount of current drawn when initially switched on to protect the equipment from damage due to large inrush currents. In this article, we will explore the application field and working principle of the B57238S0220M051 inrush current limiter.

Application Field of B57238S0220M051 Inrush Current Limiter

B57238S0220M051 inrush current limiters can be used to limit the amount of current drawn when initially switched on in electrical circuits. Examples include switches, motors, transformers, and computers. It is important to use these limiters to protect the equipment from possible damage caused by large inrush currents. In addition, a limited current flow helps to ensure that the equipment is operating safely.The B57238S0220M051 device is suited for a variety of systems, including AC, DC, and digital circuits. It is also suitable for a wide range of temperatures and environments.

Working Principle of B57238S0220M051 Inrush Current Limiter

The B57238S0220M051 inrush current limiter works by restricting the amount of current that can flow through the circuit initially. This is achieved by using a mechanical device which consists of a bimetallic disk sandwiched between two plates. When the voltage is applied to the plates, the disk heats up and bends, which restricts the flow of current.When the voltage is removed, the bimetallic disk cools down and relaxes, allowing the current flow to be returned to its original level.

Conclusion

In summary, the B57238S0220M051 inrush current limiter is a highly effective device for protecting electrical equipment from potential damage caused by large inrush currents. It is suitable for a wide range of AC, DC, and digital circuits, and is able to operate in a variety of temperatures and environments. Its working principle relies on a bimetallic disk which heats up when voltage is applied, restricting the flow of current, before cooling down and allowing the current to return to its original flow when the voltage is removed.
