Inrush Current Limiters (ICL) are essential components in the electrical industry, primarily used to reduce high inrush currents in power circuits. The CL-90 is a new and highly efficient example of this type of device that offers improved safety and reliability.

Inrush current is the unexpected flow of energy into a power supply or circuit at startup, leading to a much higher current than expected. It can cause system instability, costly shutdowns, power fluctuations, and, in extreme cases, equipment failure and fire or electric shock risk. Inrush current limiters reduce the flow of energy into the system by preventing capacitors and other components from experiencing an overload at startup, ultimately protecting the system from damage or potential hazards.

The CL-90 is designed to handle high inrush currents up to 90 A, making it suitable for larger applications such as industrial motors and process heating equipment. It has an operating voltage of 250VAC, a current rating up to 110A, and a thermal battery that allows it to withstand up to 125°C. The device is also designed to be highly efficient, with a fast response time and low thermal stability and negligible voltage drop.

The CL-90 works by limiting the amount of current that can flow through it at any given time. It employs several protection components such as temperature-controlled positive temperature coefficient (PTC) thermistors and passive current limiters in order to achieve this. When the power is turned on, the PTC thermistors provide an initial resistance, which slows and limits the load current entering the circuit. As the temperature increases, the resistance of the PTC thermistors increases, further restricting the inrush current. This process occurs quickly, allowing the limiters to respond to inrush current in just a few milliseconds.

Additionally, the CL-90 also features a built-in liquid cooling system to prevent overheating and protect the device from damage. This helps to maintain safe and consistent operation in high-demand systems.

The CL-90 is an advanced and efficient Inrush Current Limiter specifically designed for larger applications. Its high current rating, fast response time, and built-in safety features make it an ideal choice for increased reliability and protection in power circuits.
