Gas Discharge Tube Arresters (GDT) are devices used to protect electrical systems from damage caused by lightning, fault currents, and switching surges. The SL1122A450R is a Gas Discharge Tube Arrester, which provides protection for electrical systems in industrial, commercial, and residential applications. Its primary features are high insulation resistance, high nominal discharge current, and fast response time. The SL1122A450R is a robust, corrosion-resistant device designed for use in harsh environments.

The SL1122A450R is a fail-safe, high power metal oxide gas-filled arrester. It is designed to provide over-voltage protection in applications where very high discharge capability is required. The SL1122A450R is rated for a maximum continuous operating voltage of 450V. It has a leakage current of less than 1µA at 200VAC, and a minimum impulse current rating of 25kA. It also features a wide temperature range from -20 to +60°C.

The SL1122A450R is designed to protect against over-voltage conditions caused by lightning, switching, and other transient events. When an over-voltage occurs, the Gas Discharge Tube Arrester protects its surroundings from damage by triggering a very fast, high-current burst. This burst limits the voltage by consumed the excess energy. The rapid turn-off time of the SL1122A450R enables it to respond quickly to transient over-voltages, minimizing the risk of damage to other components in the circuit.

The working principle of the SL1122A450R is based on a Gas Discharge Tube (GDT) filled with a combination of gases, such as Argon, Krypton, and Xenon. When the arrester is exposed to a voltage greater than its rated voltage, the gas in the GDT ionizes and produces a high-current arc. This current passes through the arc and is absorbed by the device, limiting the surge to a safe level. Once the transient is over, the gas in the GDT returns to its normal state.

The SL1122A450R is a rugged and reliable device for providing transient over-voltage protection. It can be used in a variety of applications, such as industrial control circuits, power distribution systems, telecommunications systems, and automotive systems. The arrester can also be used for protecting sensitive electronic parts from static electricity, as it is designed to limit the voltage to a safe level. The SL1122A450R is a cost-effective solution for providing reliable protection against damage caused by transient over-voltages.
