Gas discharge tube arresters (GDT) are electrical components that provide over-voltage protection to equipment connected to AC power sources or telecommunications systems. They are usually non-linear resistors and have an active role in limiting surge voltages and dissipating them safely away from the protected equipment.

The SL1021B250RS is a GDT arrester designed for protection from electric power systems and telecommunications systems. It is a surge protective device (SPD) that is primarily used in AC power systems. The SL1021B250RS has an operating voltage of 250 volts and is typically installed on systems operating at 600 volts or less.

The SL1021B250RS has a maximum discharge current of 25kA. This high level of surge protection is achieved thanks to the GDT\'s internal design, which includes a ceramic body filled with a non-metallic, gas-filled arc gap. This gap is the active component of the GDT that is responsible for providing the surge protection. When a surge voltage occurs, the arc gap conducts current and conducts the surge safely and reliably away from the protected system.

The SL1021B250RS also has a high frequency transient suppression capability. This is achieved by a combination of an intrinsic diode network and a proprietary high frequency design of the GDT. This combination of components enables the SL1021B250RS to absorb high frequency transients and rapidly dissipate them away from the protected system.

The SL1021B250RS also features a wide operating temperature range: from -40 to +85 degrees Celsius. This allows it to be used in a variety of applications and environments. Additionally, the GDT has high surge durability, ensuring that it is able to continue providing protection for the many years of its operational life.

In summary, the SL1021B250RS is a robust GDT arrester designed for reliable protection against both AC power surges and high frequency transients. Its wide operating temperature range and high surge durability make it suitable for a variety of applications and environments. With its excellent surge protection capability and long operational life, the SL1021B250RS is a reliable and effective SPD for all power and telecommunications systems.
