Gas Discharge Tube Arresters (GDT) are an important component of electrical circuits and power systems. They are used to provide protection from lightning strikes, electrical surges, overvoltage spikes, and other disruptive events. GDTs consist of a special gas filled tube which is connected to both the surge current source and the protected equipment. When a surge is detected by the GDT, its gas is ionized and a large discharge current is generated, which is then dissipated safely into the ground. This prevents the surge from entering the protected equipment and damaging it.

The 2089-140-BT1LF Gas Discharge Tube Arrester is designed to provide protection from high-energy pulse surges, such as those encountered in electronic circuits and telecom systems. It features a fast action response and a maximum voltage rating of 6 kV. The 2089-140-BT1LF has a robust construction with a zinc foil terminal for improved mechanical strength. The GDT includes an additional plastic sleeve to protect against vibration and corrosion.

The 2089-140-BT1LF application fields are mainly in the medium and low voltage distribution systems, electronics, communication systems and lightning protection circuits. These GDTs are used to protect electronic circuits and systems from high voltages and excess currents caused by lightning strikes, electrostatic discharges, and power outages. GDTs can also be used to protect equipment from electrical transients by providing shunt paths for excess current.

The working principle of a GDT involves the passage of a high-intensity current flow when a surge is detected. This triggers an ionization of the gas inside the tube, which creates a plasma effect and causes the current flowing through the tube to reach its peak value. The surge current then dissipates through the protective conductors, earth terminations, and protective components, while the GDT recovers to its original state as soon as the surge passes.

The 2089-140-BT1LF GDT is designed to have a fast response time when handling a surge overvoltage or spike. It is capable of handling voltage variations ranging from 6 kV to 0.1 kV, with a decay rate of 0.5 kV/msec. The 2089-140-BT1LF has a maximum continuous working voltage of 3 kV. The GDT also features a low capacitance and a low leakage current when in its normal operating condition.

The 2089-140-BT1LF GDT is designed to be compact and cost-effective, making it ideal for use in space-constrained applications. It can be mounted horizontally or vertically inside an electrical enclosure and it requires no additional ground/earth connection. The GDT has a long service life and it is highly reliable.

In conclusion, the 2089-140-BT1LF Gas Discharge Tube Arrester provides reliable protection against high-energy surge voltages and spikes. It is suitable for use in medium and low voltage distribution systems, electronics, communication systems, and lightning protection circuits. The GDT provides fast response times and requires low maintenance. It is an ideal solution for providing protection from disruptive events in various industrial and commercial sectors.
