Gas Discharge Tube Arresters (GDT) also known as gas tubes or spark gap, are electrical equipment used to protect electronic devices and power systems from high electrical transient voltages, and are widely applied in high voltage power network and electronic control systems. 2037-25-A belongs to the 2037 series, which includes two types of GDT arresters.

The body material of the 2037-25-A is ceramic, and the sleeve is made of high temperature plastic. The two poles of the GDT are connected in series with two overvoltage protective components, an external shunted diode and an internal central electrode junction diode. When lightning, load switching, or other high-voltage transient over-voltage occurs, the external diodes can fast bypass the overvoltage to the ground, while the central electrode junction diode can degeneratively absorb transient overvoltage and prevent its transmission to the load side. Therefore, 2037-25-A is able to offer complete over-voltage protection to its connected electronic devices and power systems, ensuring their normal operations.

Aside from overvoltage protection, 2037-25-A is also used to protect from short-term over-current, by reducing the potential surge currents when switching on and off. This is made possible with its advanced and optimized surge window, which has been carefully designed for excellent depth of protection and minimal resistance in normal running conditions. This surge window ensures coordination with other downstream protection modules.

In terms of mechanical structure, 2037-25-A contains two poles for connection to the power supply, as well as two poles for connection to the load/ground. Its high temperature plastic sleeve can effectively protect its ceramic body from external impacts, improving its strength and durability. Its small form factor makes it easy to install and maintenance, and it also consumes low power.

In conclusion, 2037-25-A is a high-performance GDT arrester designed for protecting electronic devices and power systems from overvoltage and transient over-current. Its high temperature plastic sleeve makes it robust and durable, and its advanced surge window has an excellent depth of protection with minimal resistance in normal running conditions. As such, it is one of the most popular GDT arresters on the market and is widely applied in high voltage power networks and electronic control systems.
