Inrush Current Limiters (ICL)

An Inrush Current Limiter (ICL) is a type of electrical component designed to help protect electric circuits from damaging inrush currents. The CL-170A has become the most popular inrush current limiter on the market, providing ample protection to applications such as lighting fixtures, motors, and electronic systems. In this article, we\'ll take a look at the application field and working principle of the CL-170A ICL.

Application Field

The CL-170A inrush current limiter is designed for applications that require high current, and can handle up to 20A of continuous current and up to 100A of peak inrush current. This means that it\'s ideal for applications such as electric motors, lighting fixtures, HVAC systems, and other high-end electronic systems. Additionally, the CL-170A ICL has an operating temperature of -40°C to 105°C, making it ideal for applications in colder or hotter climates.

Working Principle

The CL-170A operates on the principle of resistive limiting, meaning that it uses a resistive element to limit inrush current. This resistive element is a thin metal sheet that is formed into a three-dimensional shape. When the power is initially applied, the resistive element produces a resistance that limits the flow of current, thus limiting the inrush current. The amount of current that is allowed to flow is dependent on the resistance of the element, as well as the voltage present.

In addition to resistive limiting, the CL-170A also employs thermal limiting. Thermal limiting works by sensing the temperature of the resistive element. When the temperature becomes too high, the circuit is automatically disengaged, thus preventing further current from flowing and preventing any damage to the device.

The CL-170A is a reliable and cost effective ICL that is able to provide excellent protection to all types of electrical and electronic circuits. By utilizing resistive and thermal limiting, the CL-170A provides ample protection against inrush currents, allowing for a better and more reliable performance of the circuit.
