Inrush Current Limiters (ICLs) are an important class of electrical components designed to protect equipment from power surges. They limit the amount of current that can flow into a load or machine when power is first turned on. The SL22 1R020 is a thermally activated, inrush current limiting switch. It is designed for small-signal applications where a limited amperage at turn-on is needed.

The SL22 1R020 uses a metallic trigger to sense the temperature of the switch as it is being turned on. When the temperature reaches a certain level, the trigger flips open, allowing the current to flow. The temperature at which the switch opens is adjustable, allowing operators to adjust the current limits as needed. The switch can be closed again either manually, or through a feedback loop that detects when the temperature has dropped below a certain level.

The SL22 1R020 is most commonly used in automotive applications, where it can protect against power surges and inrush currents from electric vehicles and other electrified machines. It can also be used in industrial and household applications, such as for protecting against power surges associated with heavy equipment being turned on. In each application, the switch can be adjusted to provide different levels of inrush current protection.

The SL22 1R020 has a number of features that make it a good choice for protecting against power surges. It has an adjustable trip point, which allows operators to fine-tune the tripping of the switch, and it has a compact design, which makes it easy to integrate into systems. Additionally, it is designed to withstand high temperatures and is rated for up to 125°C. This is important for many applications, as it can help protect against power surges associated with high temperatures.

The SL22 1R020 is simple to install and use, allowing operators to quickly set the switch to the desired current limits. It is also an inexpensive option, making it an attractive solution for many applications. The combination of its ease of use, cost-effectiveness, and adjustable trip point makes the SL22 1R020 an attractive choice for inrush current limitation.
