Gas discharge tube arresters (GDT) are devices designed to protect other electrical components from overvoltage surges or spikes due to lightning, electrostatic discharge, or power line switching. GDTs are available in a variety of sizes and power ratings, and typically consist of a ceramic housing containing two electrodes separated by a gaseous material. When the voltage between the electrodes reaches a certain level, the gaseous material ionizes and becomes conductive, allowing a current to flow through the device and thereby reducing the voltage of the source.

The 2027-20-A GDT is a specifically designed type of the GDTs family. It is designed for use in industrial, commercial, and residential applications. It is a basic two-electrode model but features a specially treated ceramic housing that protects against arc-over. The 2027-20-A GDT also features an isolating metal cylinder between the electrodes, which serves to protect the device from the effects of hazardous voltages.

The working principle of a GDT is quite simple and is based on the same principle that is used in a spark plug. When the voltage across the electrodes is below a certain level, the gaseous medium within the device remains non-conductive. However, when the voltage between the electrodes exceeds the breakover voltage, the gaseous medium becomes ionized and a spark or current arc is formed between the electrodes, thus reducing the voltage across them. The amount of energy that the device can absorb depends on the design as well as the type of materials used.

The 2027-20-A GDT is designed to be used in a number of applications ranging from residential and industrial to commercial. It can be used to protect various types of electrical systems from overvoltage spikes, and due to its high electric breakdown strength can be used to protect electrical systems from overvoltage events caused by lightning strikes. The device can also be used to protect electrical systems from electrostatic discharge or power line switching.

The 2027-20-A GDT is a well-constructed and reliable device that is capable of providing a high level of protection for electrical systems from the effects of high voltage surges. The device is designed with a long life expectancy, and can handle a wide range of voltages and power ratings. It is an ideal device for use in a variety of applications ranging from residential, commercial, and industrial.
