Gas Discharge Tube Arresters (GDT) are devices used to protect electrical and electronic circuits from hazardous voltages caused by lightning - induced transient surges. The 2039-80-BT1LF arrester is a voltage-limiting type arrester which provides protection against alternating and direct currents with surge-slow and high-frequency transients.

GDT arresters are typically constructed from a gas-filled tube that encloses two metal electrodes, typically connected to two external terminals. When the device is exposed to an over-voltage, the gas-filled tube ionizes and temporarily acts as a conductor. This ionization process limits the voltage across the tube and dissipates the lightning-induced surge transient.

The 2039-80-BT1LF arrester is rated to protect circuits from over-voltage to a peak of 150kV. The internal arc over-voltage is approximately 8kV. The 2039-80-BT1LF arrester is constructed from an ultra-durable K20 ceramic tube and has a long life and excellent dielectric strength. The arrester is highly resilient to extreme temperatures, vibration, and moisture.

The 2039-80-BT1LF arrester\'s working principle is based on the process of ionization. When a high voltage surge is received by the arrester, the gas-filled tube becomes ionized and a current is conducted through the gas. This process limits the voltage and dissipates it in the form of heat, thus preventing it from damaging sensitive electrical and electronic components. The process of ionization does not continue for long, and it takes a few milliseconds for the arrester to reset itself.

The 2039-80-BT1LF arrester is suitable for use in electrical and electronic systems, such as telecommunications systems, power distribution systems, and cable networks. It is particularly useful for providing protection against direct lightning strikes, which can cause severe damage to sensitive components. The arrester is also suitable for providing protection against transient voltages caused by switching or surges from other parts of the electrical network.

The 2039-80-BT1LF arrester is a highly reliable device that provides consistently reliable protection against over-voltage. It is robust and resistant to harsh environmental conditions, making it suitable for use in a wide range of applications. With its long life and excellent dielectric strength, it is an ideal choice for any application that requires reliable protection against dangerous voltage surges.
