The Gas Discharge Tube Arresters (GDT) become increasingly important in many electrical applications and are considered essential in places where overvoltages may occur due to switching operations, lightning strikes, or other causes. GDTs are commonly used to protect electrical equipment, as they dissipate high energy voltage spikes, allowing lower-voltage currents to pass through relatively unscathed.

The 2063-25-ALF GDT is used in protecting electrical equipment and systems from switching operations, lightning strikes or other transient overvoltage damages. This arrester uses zinc oxide varistor cores at both ends to control voltage variances in the range of plus and minus five kV. They consist of two resistors in series with each other. The inner one is made of ZnO, which offers a higher resistance to high voltage, and the outer resistor is made of metal oxide, which provides a low resistance at low voltages.

The working principles of the 2063-25-ALF GDT are quite simple. The arrester works by taking the high voltage by-passing the thermal fuse that isolates the GDT, and passing through the zinc oxide varistor cores. At a certain voltage, the Zinc Oxide varistor cores breaks down, allowing the current to flow to the ground, thereby preventing the breakdown of the electrical equipment. When the voltage exceeds the preset threshold, the fuse opens, isolating the arrester from the system and preventing any further current flow to the electrical equipment.

The 2063-25-ALF GDT have a wide range of applications, including but not limited to surge protectors, DC power sources, and lightning suppressors. It is the perfect solution for protecting electrical equipment from both transient and permanent overvoltages. It is also suitable for protecting against arcing, over-current, and arc faulting.

In conclusion, the 2063-25-ALF GDT is a reliable and effective arrester that offers protection from transient overvoltages. Its Zinc Oxide varistor cores break down at a certain voltage to redirect current away from the electrical equipment, while its fuse isolates the arrester from the system when the voltage exceeds the preset threshold. It is suitable for a wide range of applications and provides reliable protection from both transient and permanent overvoltages.
