Inrush Current Limiters (ICL) are devices used to prevent short-term, instantaneous high current demand and large inrush current when power is applied to a system. SL22 5R006 is a ICL series designed to minimize inrush current, which are made from high-grade materials with excellent electrical and environmental properties and high temperature resistance. These devices can be used in various applications even in harsh industrial settings.

The SL22 5R006 series consists of six models which provide various ratings allowing users to choose their desired combination for their application, which include voltage ratings from 16VAC to 250VAC and I2t ratings starting from 3.7A2s to 10A2s. These devices can withstand continuous operating temperatures ranging from -55°C up to 125°C.

SL22 5R006 series\' working principle is based on a thermally bimetallic device with a positive temperature coefficient. The device is designed with two metal plates which are joined at one end. When an inrush current passes through the device, a voltage is induced across the metal plates, creating thermal expansion. The relationship between temperature and resistance ensures a quick temperature increase with an increased current flow. This thermal expansion, then causes the plates to bend, creating an expanding arc gap.

The heat generated by the current flow is dissipated through the two plates, causing the gap to become larger. This increases the device\'s resistance and effectively reduces the current. With the resistance rising, the difference in voltage between both plates decreases, allowing the two plates to cool off and return to their original positions. This mechanism ensures that inrush conditions are dampened and controlled.

The SL22 5R006 series boasts several advantages. It operates on low voltage, allowing it to work even under off-grid conditions. It also offers flexibility, as it can be mounted in either vertical or horizontal positions. It has a low leakage current, making it efficient, and an adjustable time delay, allowing users to set the delay time for their requirements. The device also provides maximum protection from electrical shock and voltage surges.

The SL22 5R006 series is suitable for a variety of applications, such as Surge and Spike protection, Building Automation System, Power Supply Units, Lighting Control Systems, Industrial Equipment and Appliances, and Medical Devices. These devices can be used in domestic, industrial and commercial settings, and are suitable for applications where instantaneous and long-term inrush current needs to be restricted or limited.

In conclusion, the SL22 5R006 series of Inrush Current Limiters can effectively protect electrical systems from high and sudden current demands and surges, allowing them to run safely and efficiently. It operates on low voltage, is flexible and easy to install, and can be used in a variety of applications.
