Gas Discharge Tube Arresters (GDT) are used for the protection of equipment against electrical overvoltages caused by lightning or switching operations. The 2049-25-BT1LF is a GDT Arrester designed to protect against direct lightning strikes, and is suitable for industrial and commercial applications. This article will discuss the application field and working principle of the 2049-25-BT1LF.

The 2049-25-BT1LF is rated for use in locations where the probability of lightning strikes is low to medium. It has a maximum continuous operating voltage (MCOV) of 25 kV, a nominal discharge current (Id) of 25 kA (10/350 µs) and a maximum discharge current of 31.5 kA (10/350 µs). The arrester is designed to limit the current that can pass through it to a safe level. In the event of a lightning strike, the arrester can act as a short-circuit, which dissipates the electrical energy, reducing its effect on the protected equipment.

The working principle of the arrester is based on the action of an ionized gas as an electrical breakdown medium. When the arrester is energized and current begins to flow through it, an electric field is created in the gap between the anode and the cathode. This electric field ionizes the gas and the ionized gas forms a conductive path between the anode and the cathode, allowing current to flow. When the current reaches the arrester’s maximum current rating, the electric field is dissipated and the ionized gas dissipates, breaking the path between the anode and the cathode and stopping the flow of current.

The 2049-25 BT1LF Gas Discharge Tube Arrester is designed for use in a variety of applications, including telecommunications, digital, security, medical, and industrial equipment. It is suitable for applications in outdoor installations and offers good protection for equipment against lightning and transient overvoltages. The arrester has a lower maximum discharge current rating compared to other GDT Arresters, however, it still provides adequate protection for most applications. It has a long service life and is relatively easy to maintain. The arrester is available in various sizes and can be adapted to fit different requirements.

The 2049-25-BT1LF Gas Discharge Tube Arrester is an effective and cost-effective solution for protecting electronic equipment against excessive electrical overvoltages caused by lightning or switching operations. It has a high current rating and a long service life, making it a suitable choice for many applications. It is designed for outdoor installation and offers protection against transient overvoltages. The arrester’s working principle is based on the action of an ionized gas as an electrical breakdown medium, which dissipates the electric field when the current reaches the arrester\'s maximum current rating.
