Inrush Current Limiters (ICLs) are electrical devices that are used to limit the large inrush of current to an electrical system when the system is first switched on. They are commonly used in power applications such as air conditioners and refrigerator compressors, where large fluctuations in current can cause damage to the system. The SG303 is an example of an ICL that is designed to limit inrush currents in power applications.The SG303 is a self-contained device that is designed to limit inrush current to target specified levels. It is constructed in a variety of sizes and can be used in AC and DC circuits. It works by using a combination of a thermistor and a semiconductor element to limit the inrush current. The thermistor acts as a time-delay element, while the semiconductor is used to switch the device on and off.When the device is first switched on, the thermistor allows a small amount of current to flow through the system, allowing the device to warm up slowly. The small amount of current is limited so as to prevent any large fluctuations in current that can damage the system. After a few seconds, the thermistor increases the current to the required level, allowing the system to reach its rated capacity.The SG303 is a reliable and robust device and is commonly used in commercial and industrial applications. It is easy to install and can be used in a wide range of voltages and currents. It is also capable of dealing with a wide range of inrush current levels. The device is intended for use in applications where the system is exposed to spikes in current due to large fluctuations in demand or because of switching components.When installing an SG303, it is important to keep in mind the system\'s voltage and current levels. It is also important to make sure that the system is properly wired and that all connections are secure. Proper installation and maintenance of the device are essential to ensure safe and reliable operation. The SG303 is an effective and reliable device for controlling inrush current in power applications. It is simple to install and provides consistent, reliable protection against large current spikes. It is also capable of dealing with a wide range of currents and voltages, making it an ideal choice for a variety of applications.
