Gas Discharge Tube Arresters (GDT) have been used as surge protection devices for a variety of electrical applications. They are particularly used for protection against external and internal transient voltage surges, which include lightning and lightning-caused currents. GDTs are commonly used in high-voltage supplies, telecommunication networks, and in automotive and aerospace applications. A typical GDT consists of a specially designed insulated tube, usually made of a dielectric material, which contains two electrodes. The PMT809004F is one such GDT.

The PMT809004F application field can be divided into three categories: high-voltage AC, low-voltage AC and low-voltage DC. The PMT809004F is suitable for use in protection of electrical systems against lightning, increasing energy levels occurring due to switching surges and utility line disturbances. It can also be used in applications where protection against electrical noise and overvoltage is required.

The PMT809004F has a wide voltage range, making it suitable for various applications, and it offers excellent absorption capacity. Its high surge suppression ability and fast response time make it especially suitable for power surge protection. Furthermore, it features a temperature coefficient that ensures reliable service over wide temperature ranges.

The working principle of a GDT is based on the fact that when it is subjected to a higher electrical voltage, it stores energy in a gaseous form until it reaches its breakdown voltage. Once this value has been exceeded, a spark discharge occurs, which neutralizes the excess energy. The heat created by this process induces a thermal current, which then causes the electrode and the dielectric material to restore their normal state. This process repeats itself, thereby protecting the equipment from overvoltage or surges.

The PMT809004F is a high-performance gas discharge tube that provides superior lightning and surge protection while enabling fast response times. It features an inherently low capacitance, which reduces the chances of transient voltage disturbances in electrical systems, thus providing reliable protection. Its wide voltage range makes it applicable to a variety of applications and its high surge suppression ability ensures its reliability in providing protection against overvoltage or surge. The PMT809004F is also easy to install, making it an ideal choice for providing lightning and surge protection.
