Gas Discharge Tube Arresters (GDT) are surge protection devices that are used to protect sensitive electronics from electrical transients in the environment. GDTs are typically used in AC/DC, low voltage, and power supply applications. The GTCS25-401M-R02-2 is one such device. The following paragraphs will discuss the application field and working principle of this particular GDT.

The GTCS25-401M-R02-2 is a high-voltage, metal oxide arrester designed to protect low-voltage DC systems from large, short-duration overvoltage conditions caused by lightning. It is suitable for use in applications operating from 24 to 380 Volts AC/DC, making it ideal for applications in data centers, telecom networks, industrial systems, and other sensitive electronics. The device has an ultra-high speed response time of 10 nanoseconds, which makes it highly suitable for lightning protection applications where surges must be responded to quickly to prevent damage.

The working principle of the GTCS25-401M-R02-2 is based on the gas-filled spark gap technology. When an overvoltage occurs, the arrester facilitates a spark gap that opens up to create a flow of electrons between the metal oxide elements in the arrester. This lowers the voltage, which safeguards the components from damage. This spark gap will close once the peak voltage has been reached, and the arrester is reset to its natural state.

The GTCS25-401M-R02-2 is designed with a resistor-like characteristic meaning that in normal conditions, the spark gap does not conduct and no current flows between the metal oxide elements. However, when an overvoltage occurs, the spark gap will open and create a low-impedance path for the current. This then reduces the voltage across the spark gap, protecting the system from damage.

The GTCS25-401M-R02-2 is designed to be resistant to environmental influences such as extreme temperatures and high humidity levels. It also has a high per-pulse surge current handling capability of 10kA, making it suitable for high peak voltage protection applications. Additionally, the arrester is designed to withstand multiple currents without any degradation in performance.

In conclusion, the GTCS25-401M-R02-2 is a high-voltage, metal oxide arrester designed to protect low-voltage DC systems from large, short-duration overvoltage conditions caused by lightning. It is suitable for use in applications operating from 24 to 380 Volts AC/DC, and has an ultra-high speed response time of 10 nanoseconds. The working principle of the arrester is based on the gas-filled spark gap technology, which is activated when an overvoltage occurs. The arrester is designed to be resistant to environmental influences, has a high per-pulse surge current handling capability, and is capable of withstanding multiple currents.
