Gas Discharge Tube Arresters (GDT) is an important and cost-effective solution for surge protection against high-voltage impulse currents. 2061-23-ALF is used primarily in applications where surge or transients up to 21kV need to be managed. This range of GDT are designed for the protection of low voltage power circuits.

A GDT is composed of a gas-filled tube with two electrodes. A positive voltage appearing on the electrode connected to the protective device triggers an arc that suppresses excessive current. The arc acts as an open circuit, interrupting the current and resetting itself in a few microseconds.

2061-23-ALF consists of three components: a cylindrical anode, an insulated rod cathode, and a gas-filled tube. The anode is connected to the protected lines, while the cathode is connected to the common. The gas-filled tube encloses the two conducting elements and contains either Sulphur Hexafluoride(SF₆) or Nitrogen gas.

When a high voltage spike affects the arrester, the electrons move more rapidly towards the anode of the GDT, increasing the current. The increase of the current generates heat, which creates a localized ionization of the SF₆ gas. This gas has a very low dielectric strength which causes an arc. The arc acts as a bridge, conducts the current and breaks the circuit. Afterwards, the arc self-extinguishes, as the gas reverts to its normal non-ionized state.

2061-23-ALF is designed for use in a wide range of applications, including residential, commercial and industrial installations. This arrester can be used to protect power lines from impulse-induced transients, lightning-induced surges, and failures in other electronic equipment connected to the power line. In addition to surge protection, 2061-23-ALF helps reduce downtime for maintenance and repairs, which can result in significant cost savings.

GDT arresters are often used in combination with other surge protection devices, such as metal-oxide arresters and transient voltage suppressors. This is due to their ability to provide a high degree of protection against transient overvoltage. When using it with other surge protection devices, it helps to reduce the number of devices used and minimizes the installation and operational costs. In addition, GDTs are more reliable than other surge protection devices, and can withstand multiple events before needing to be replaced.

2061-23-ALF is an important tool for protecting sensitive electronic equipment from high-voltage impulses. This arrester is reliable, cost-effective, and easy to install and maintain. With 2061-23-ALF, businesses and individuals can be sure their safety and operations are well-protected from the effects of surge currents.
