Gas Discharge Tubes (GDT) are an important type of surge protection device. They serve to protect electrical equipment and computer networks against lightning strikes and other electrical surges. A GDT is usually composed of two electrodes separated by a glass/ceramic tube. Gas, usually air, is present in the middle of the tube.

PMT3(310)15004 is a type of GDT, rated for up to 15kV. It is a three-electrode gas discharge arrestor, which uses a spark gap between the electrodes to limit the flow of surge current. The two inner electrodes are made of high-quality molybdenum with an outside diameter of 3mm. The electrodes are insulated from each other by a ceramic disk and a spacer.

The PMT3(310)15004 is used in a variety of applications. It is commonly used in industrial, commercial and residential applications to protect against lightning strikes and other types of electrical surge. It is also used in telecommunications systems, such as power lines, and in the automotive industry. The device can be used to protect sensitive electronic components, such as computers and other equipment, from electrical surges.

The working principle of the PMT3(310)15004 is based on the concept of the spark gap. When electrical surge current flows through the gap, ions are generated. These ions act as a “bridge” between the two electrodes, which helps to reduce the surge current. The ceramic disk and spacer inside the tube help to further reduce the current flow.

The PMT3(310)15004 also has a response time of less than one nanosecond, which allows it to react quickly and protect sensitive equipment from expensive or dangerous damage. It is also resistant to current surges up to 15kV, and can withstand repeated flows of the surge current.

Overall, the PMT3(310)15004 is an effective surge protection device that can help protect sensitive equipment from damage. It can be used in a variety of applications and is designed to work quickly and reliably. And, thanks to its relatively small size, it can be easily installed in both industrial and residential settings.
