Inrush current limiters (ICLs) are designed to limit the amount of inrush current, the amount of current that a device or system draws at start-up or after a power interruption. B57238S0479M051 ICLs can help prevent damage and reduce energy costs while increasing the system efficiency and reliability.

Inrush current limiters are specifically designed to prevent overloads during start-up of electronic systems.Unlike other components that can be used to limit inrush current, ICLs are designed to withstand repeated power cycling without degradation. The B57238S0479M051 is equipped with a thermal protection device that will shut off the unit if it exceeds the specified temperature range.

The primary function of B57238S0479M051 ICLs is to prevent potential equipment damage due to large inrush currents associated with motor starts, compressors, contactors and other inductive loads. These devices limit the amount of inrush current, allowing the system to start more efficiently, while also preventing excessive current from passing through the system. Additionally, ICLs can help protect system components from power surges and voltage drops that can occur in electrical systems.

The B57238S0479M051 ICLs contain a conductive polymer film material which is capable of controlling the inrush current by creating a nonlinear resistance path when the current is larger than the desired level. The nonlinear characteristic of the polymer film is due to its property of varying the resistance depending on the amount of voltage applied. Thus, it can act as a resistor, a diode or a combination of both depending on the application.

The working principle of the B57238S0479M051 ICLs is simple and effective. The current limiting effect occurs when the voltage across the device increases in a nonlinear fashion due to the electrical field generated by the conductive polymer material. As the power supply voltage passes through the device, the electrical field causes a resistance that regulates the flow of inrush current, limiting it to a predetermined level.

The B57238S0479M051 ICLs can be used in a variety of applications, including motor controls, AC/DC switching supplies, power supplies, fractional horsepower motors, and lighting systems. They are also used in sensitive electronic equipment and instrumentation as protection against power spikes. Their ability to limit inrush currents makes them a must-have component for any system where large amounts of inrush currents can cause damage to other components.

The B57238S0479M051 ICLs are an essential part of any system that requires protection from inrush current. Their nonlinear resistance properties create a precise limit on the inrush current, while also providing protection from power surges and voltage drops. This makes them an ideal choice for any application where reliable and effective inrush current control is needed.
