Inrush Current Limiters (ICL) are a form of surge protection that limits current when a power system is turned on. The SG326 is a popular type of ICL that is used in many industries and applications. In this article, we will explain the general application field and working principle of the SG326.

The SG326 ICL is a compact, easy-to-install surge protector with a wide range of applications. It is commonly used in industrial equipment such as motors, pumps, and controls, as well as in electrical appliances and consumer electronics. The device works by limiting inrush current when an increased load is applied to a power system, such as when a motor starts up. This helps to protect the system from both thermal and electrical damage that can be caused by high surge currents.

The SG326 ICL is designed to operate at a set current level, which is adjustable from 0.1A to 3A. The device is designed to be tolerant of high voltages, operating between 250VAC and 600VAC. It is also resistant to vibration and corrosion caused by chemicals and environmental factors. Additionally, the device has excellent response time, switching from 0-3A in only 1ms.

The working principle of the SG326 ICL is based on a combined thermal/magnetic protection element that limits inrush currents. When the system is turned on, the ICL detects an increase in current and applies a “clamp” of a preset value. This prevents excessive current from damaging the system. The ICL is triggered by the current but is reset by the voltage, allowing the power system to operate with normal current levels once the inrush current has subsided.

The SG326 ICL is used in a variety of applications in commercial and industrial environments. It is ideal for protecting motors during start-up and power surge protection in consumer electronics. The device is also suitable for use in high-temperature environments, such as near ovens and boilers, or in areas of frequent vibrations. The compact size and easy installation of the device makes it an ideal choice for many applications.

In conclusion, the SG326 is a popular Inrush Current Limiter (ICL) with a wide range of applications. The device limits inrush currents when an increased load is applied to a power system, helping to protect the system from thermal and electrical damage. The working principle of the SG326 is based on a combined thermal/magnetic protection element that limits inrush currents. The device is suitable for use in commercial and industrial environments, as well as high-temperature and vibration environments.
