Gas Discharge Tube Arresters (GDT)

A Gas Discharge Tube Arrester (GDT), also known as a Gas Tube Surge Arresters, is a device used to protect electrical components from damage due to electrical surges. The 2056-25-B3LF GDT is a three-stage unit which offers excellent protection in both medium and low voltages up to 25kV.

Application field

The 2056-25-B3LF GDT is designed for indoor and outdoor applications, specifically in telecommunications, power distribution, signal transmission, and process control systems. Its three-stage design provides effective protection against both high-speed and slow surges in medium and low voltages up to 25kV. The wide range of voltages makes the 2056-25-B3LF GDT suitable for use in all sorts of applications, ranging from industrial equipment to power plants.

Working Principle

A GDT works by diverting surge currents around sensitive components, limiting the voltage that it is exposed to. When an electrical surge occurs, the GDT operates in three stages: the voltage is initially increased to a safe peak level, then it is slowly reduced over time, and finally the current is diverted away from the sensitive components.When the GDT initially begins to divert current, the voltage is scaled depending on the amount of voltage supplied, meaning it can handle both high and low levels of voltage with ease. The initial stage is critical to the performance of the GDT as it sets the safe peak voltage level that components are exposed to. During the second stage, the voltage is slowly reduced and finally, during the third stage, the current is diverted away from important components.

Conclusion

The 2056-25-B3LF GDT is an excellent choice for both indoor and outdoor electrical surge protection. Its three-stage design ensures effective protection in all sorts of applications, up to 25kV, and can handle both high and low voltages. By diverting the current away from sensitive components, the GDT can effectively protect them from electrical damage, making it an invaluable addition to any system.
