Gas Discharge Tube Arresters (GDT)

A Gas Discharge Tube Arresters (GDT) is a device designed to protect electrical equipment against overvoltage strikes. In a GDT, a small, electrically conductive, gas-filled tube is connected between two electrical terminals. The gas inside the tube is ionized when an overvoltage strike occurs, allowing electrical current to flow between the terminals, thereby dissipating the overvoltage. GDTs are used in a wide range of applications, from power systems to industry and telecommunications, because of their reliability and cost-effectiveness.

B88069X7240B502 Application Field

The B88069X7240B502 arrester is particularly suitable for low- and medium-voltage installations and is used in applications such as household appliances, solar panels, uninterruptible power supplies (UPSs), light poles, railroads, street lighting, and industrial machines.

The arrester is designed to be installed outdoors in accordance with EN 50463, EN 50522, and EN 62305-4 standards and is rated with a maximum voltage of 690 V. Highest creepage and clearance distance, together with IP66 protection, make the B88069X7240B502 the ideal choice for outdoor applications.

In addition, the low nominal discharge current makes the GDT suitable for sensitive equipment such as solar panels and other sensitive electrical appliances.

B88069X7240B502 Working Principle

When an overvoltage strike occurs, a high voltage is applied across the two terminals of the GDT. The high voltage causes an ionization of the medium within the GDT, allowing a discharge current to flow to the ground. The ionization of the gas medium is suppressed by the internal design of the GDT, so that when the external overvoltage strikes are removed, the arrester is reset and current no longer flows.

The B88069X7240B502 GDT has an advanced design based on the Gas Discharge Teeth (GDT) principle, which enables a highly reliable discharge current to the ground. It is designed to dissipate a maximum discharge current of 24 kA, and the housing is made of metal with superior insulation properties.

The GDT is also designed to be compatible with a variety of installation types. It can be used with two-position mounted type, earth mounted, or wall-mounted models and is designed to protect against the most common overvoltage spikes.

The B88069X7240B502 GDT is specifically designed for use in power banks, industrial machines, solar installations, railroads, and overseas communication stations. It can be used to protect against lightning strikes as well as other electrical disturbances.
