Gas Discharge Tube Arresters (GDT) are powerful components used for power protection. They are comprised of a gas envelope, external shell and two electrodes. The GDT works by utilizing a constant flow of current between the electrodes that sweeps the entire surface of the gas envelope, directing electricity into the gas. This, in turn, creates an electrical field, which is capable of handling high voltages.

The VS450A is a GDT specifically designed to protect against impulse and direct lightning strikes. Its robust construction is ideally suited for harsh environmental conditions.

The construction of the VS450A includes several impressive features. First, the external shell is manufactured using PBT, a thermoplastic typically used in the construction of durable, long-lasting components. Additionally, the electrodes are constructed of corrosion-resistant nickel-plated brass. This enhances the overall durability of the device.

In terms of performance, the VS450A is capable of handling voltage up to 450V, with a maximum current rating of 2.5kA. The device also features a reliable surge current capability and a superior breakdown voltage.

In terms of application fields, the VS450A is widely used in the protection of electrical equipment, such as control boxes, junction points, communication lines and more. Additionally, it is suitable for use in surge protective devices (SPDs) for industrial and commercial applications.

The working principle of the VS450A is fairly straightforward. The device works by discharging a large amount of electricity into the gas envelope. This electricity is then transferred to the terminals, and is dissipated safely to ground. In the event of a lighting strike, the VS450A is capable of absorbing the excessive surge in voltage, minimizing any damage to the protected equipment, and protecting personnel from potential shocks.

The VS450A is a reliable and efficient GDT that is ideal for power protection in a variety of harsh environments. With its robust construction and impressive performance, the device is capable of providing reliable protection against lightning strikes and other power-related issues.
