Inrush Current Limiters (ICL) are devices used to protect electrical systems from high inrush currents generated when a circuit is initially energized. An example of such a device is the SL15-25004. This device works by limiting the current when power is first applied and then gradually increasing the current path until the rated current of the device is reached.

The SL15-25004 Inrush Current Limiter is a compact, sealed, self-contained device that combines an NTC thermistor and a thermal cut-off element to control the output current from a power source. Once a voltage is applied to the device, the thermistor rapidly responds and limits the initial current. This limits the current to the rated value of the device. Gradually, as the temperature of the thermistor warms up, the resistive value of the thermistor continues to reduce thus allowing more current to flow and reach the rated current level of the device.

The SL15-25004 Inrush Current Limiter is well-suited for a wide range of applications such as motor control, LED lighting and power conversions. For example, in motor control applications, if a motor is switched on, it draws large current which can cause spikes and disturbances in the system. The SL15-25004 limits such inrush currents and helps in preventing these disturbances. Similarly, in LED lighting applications, current spikes can cause the LED to fail prematurely. The SL15-25004 limits the inrush current thus helping to extend the life of the LEDs.

The SL15-25004 is also used for power conversion applications. Here, large inrush currents can lead to overloads and circuit breakers being tripped if maximum current levels are exceeded. The SL15-25004 limits inrush currents thus preventing this from happening.

The SL15-25004 Inrush Current Limiter can also be used to protect other equipment such as power supplies, controllers and regulators. By limiting the inrush current, it can help prevent damage to the circuitry. It can also be used in automation systems and to provide passive current control.

Overall, the SL15-25004 Inrush Current Limiter is a compact and reliable device that is suitable for a wide range of applications in the industrial and energy-saving sector. Its ability to limit inrush currents helps in protecting and extending the life of the equipment and systems it is used with.
