Inrush Current Limiters (ICL) are devices that have the ability to limit the inrush of current, even when a large energy storage capacitor is connected to the power line, thereby reducing the stress placed on an electronic circuit and helping to ensure the circuit\'s safety. The CL-190B is a type of ICL specifically designed for protection against voltage surges. It is a very effective and reliable unit that can provide protection for a variety of applications.

The CL-190B utilizes a four-pole clip-type contact mechanism to limit inrush current, allowing the circuit to be protected even when disconnected from the power line. This type of contact mechanism has been proven to be more effective than other standard contact mechanisms, and is capable of limiting incoming current to levels as low as one milliamp.

The CL-190B\'s design also helps to reduce the negative effects on the circuit due to the inrush current surge. The unit is designed with a low-loss silicon diode, which helps to absorb energy in the form of heat energy and provide protection against voltage surge events. It is also designed with a capacitor discharge circuit, which helps to limit the current flowing through the contact by quickly releasing energy stored in the unit\'s internal capacitor.

The CL-190B is most commonly used in industrial applications such as power transmission and distribution lines, and in electronic equipment used in the telecommunications industry. It is also used in motor control equipment to control motor start-up current, as well as to protect sensitive components from voltage surges. Additionally, the unit can be used in Home Office and Office Equipment (HO/OE) applications to provide protection against power surges.

The working principle of the CL-190B is simple, yet effective. When an over-voltage surge occurs, the unit limits inrush current by immediately entering a "steady-state" contact state. This contact state prevents the surge from entering the circuit, and acts as a buffer between the source and the load. The unit is designed to be able to automatically reset itself and reset the current limit to its original state after the surge has passed. This ensures the safety of the circuit while also providing high levels of protection against surges.

Overall, the CL-190B is an effective and reliable device for protecting against voltage surges. Its four-pole contact mechanism and low-loss silicon diode make it one of the most trusted ICLs on the market. Its capacitor discharge circuit and self-reset feature ensure that the unit is ready to protect against any surge event.
