Introduction to Inrush Current Limiters (ICL)

Inrush current limiters, usually referred to as ICLs, are devices designed to limit the amount of current that flows into an electrical circuit. An ICL is a type of electromechanical device used to control the rate and magnitude of current that enters a system.

ICLs are typically used in applications where it is necessary to reduce overcurrent inrush currents, protection for sensitive electronic equipment from overcurrent loads, and provide long-term stability and protection in circuits. They can be used in a wide range of applications including air-conditioning, lighting, motor control, and other electronics-based applications.

MS22 10008-A Application Field and Working Principle

MS22 10008-A is an Inrush Current Limiter (ICL) used to limit the instantaneous current or inrush current that flows into an electrical circuit. It is a solid state product that uses a special combination of metal oxide varistors (MOVs) and resistors to limit the current. The ICL consists of two parts, the main current clamp section, made up of the metal oxide varistors (MOVs), and the current control section, which is made up of the resistors. The MOVs are responsible for limiting the inrush current while the resistors are responsible for limiting the rate of current that flows into the circuit.

When a voltage is applied to the ICL, it will initially “absorb” the current, i.e. it will act as a resistor which allows a relatively low resistance path for the current to travel through. As the current continues to flow through the ICL, the MOVs will gradually become charged and begin to reduce the amount of current that is allowed into the circuit. The resistors will then help to maintain this reduced current level until the voltage is removed from the ICL. In this way, the ICL limits the inrush current and provides a stable current level to the device.

MS22 10008-A is used in applications such as air conditioning, lighting, motors, electronic equipment, and other power loads. It helps to ensure that the circuit does not experience damaging inrush current, which can lead to serious problems. It also helps to protect sensitive electronics from power surges. Its relatively low cost and compact design make it a popular choice for many projects.
