Gas Discharge Tube Arresters (GDT) are protective devices that are mainly used to protect sensitive electronic equipment from damage due to voltage transients. The 2056-47-B3LF GDT is specifically designed for use in applications where voltage protection is required such as telecommunications systems, industrial control, power systems and instrumentation.

The 2056-47-B3LF GDT is a two-terminal device consisting of a metal oxide gas filled glass envelope with two electrodes. The electrodes are connected to a resistive film or gauge and to the gas-filled tube. The resistive film or gauge can be selected to provide the desired voltage protection level and is the primary element in the operation of the arrester. The gas in the tube is the secondary element that provides the ultra-fast response time needed to prevent catastrophic voltage damage.

The 2056-47-B3LF GDT utilizes the standard principle of avalanche conduction for suppression of high voltage pulses. When the voltage applied to the GDT reaches the breakdown point of the resistive film, avalanche conduction occurs and current flows between the two electrodes of the GDT. The resistance in the film is reduced to provide a low resistance path for the surge current. This is known as "clamping" and is the primary means of protection afforded by the GDT.

Once the surge current is allowed to flow, it is suppressed to a safe level by the gas contained within the GDT. This gas, typically sulfur hexafluoride, is pressurized to different levels for different applications. As the surge current passes through the tube, it ionizes the gas, breaking it down into ionized particles, which create an additional resistance to the surge current. This resistance helps to suppress the surge current quickly and effectively.

The 2056-47-B3LF GDT is designed to provide protection against a wide range of voltage levels. It is suitable for use in applications such as telecommunication systems, industrial control, power systems, and instrumentation. It also provides effective protection against lightning impulses, high voltage transients and power line surge penetrations. Additionally, it meets all industry standards for safety and quality. Its unique design allows for easy installation and maintenance, making it an ideal solution for any voltage protection needs.
