Gas Discharge Tube Arresters (GDTs) are widely used in electrical applications as an overvoltage protection device. They can be found in power grids, telecommunication lines and many other places where an electrical surge or surge of energy needs to be controlled and routed. GDTs are electronic components that use a gas filled tube to control the voltage. The key to understanding GDTs is to understand their working principle.

The working principle of GDTs is relatively simple. Gas-filled tubes (GFTs) are filled with a mixture of inert gas such as nitrogen, argon or sulfur hexafluoride. When an overvoltage surge occurs, the GFTs become charged with an electric current and the gas becomes ionized. This creates an electrical arc inside the GFT which acts as an impedance and restricts the flow of electricity. The amount of device impedance is determined by the gas pressure and composition of the GFT as well as the dimensions of the GFT.

PMT3 (310) 23004 is one of the most widely used GDTs and is used in applications where a reliable voltage control and variable overvoltage protection is required. PMT3 (310) 23004 is a unique device that combines specific proprietary materials and design techniques which make it suitable for a wide range of applications. It can be used in power supplies, protection circuits, surge protectors, overvoltage limiters, circuit breakers, lightning protection systems and more.

PMT3 (310) 23004 devices are designed with a triple-layered steel core that consists of first and second layers of steel and an inner layer of stainless steel mesh that creates a redundant, low impedance spark gap that breaks down overvoltage surges. A ring-shaped resetting electrode is positioned between the steel core and the external insulation, which ensures the device is not permanently damaged after an overvoltage surge. The device is designed to react quickly to voltage surges, thus ensuring the protection of the system in the event of a power surge. The PMT3 (310) 23004 also features a low let-through voltage, meaning it can protect expensive electronic components from power spikes and other overvoltage occurrences.

PMT3 (310) 23004 is a dual-purpose device that can be used for both overvoltage protection and lightning surge protection. In lightning surge protection, the device can be set to either limit the current in the event of an overvoltage event, or to divert the current to a safe path away from sensitive electronics. Its excellent lightning strike current capacity makes it a preferred device for many applications. The PMT3 (310) 23004 has been designed to meet IEC 61000-4 standards for surge protective devices, allowing it to be used in any application that needs reliable overvoltage protection.

The PMT3 (310) 23004 is an excellent choice of device for a wide range of applications, and its versatile design has made it a popular choice for power engineers and telecom technicians. Its robust structure and superior protection against overvoltages makes it a reliable and effective device for both Lightning Surge Protection and Overvoltage Protection.
