Gas discharge tube arresters, or GDT, are essential components in electrical systems, meant to protect against lightning strikes and voltage transients. Called lightning protection systems, GDTs are devices used to minimize damage from erroneous surges of electricity. The SE140, in particular, is a GDT that is designed to provide the highest level of lightning protection available in a single component.

SE140s are hermetically sealed AC withstand and surge arresters that employ several gas discharge tubes (GDTs). Gas discharge tubes contain insulating gas saturated with a high voltage, making them ideal for protecting electronics from voltage transients. The GDTs incorporate two electrodes suspended in the gas, an anode and a cathode. When an electrical impulse passes through the two electrodes, the high voltage on the GDT creates a spark jump, where the impedance drops dramatically to zero volts. This spark jump helps to absorb the voltage surge effectively, allowing it to be redirected harmlessly away from valuable equipment.

This design also ensures the SE140 can perform in all types of transient surges, from high frequency induced currents to low frequency waves. Additionally, the SE140\'s unmatched surge protection specification margin enable it to provide incomparable levels of protection for multiple media access control (MAC) and twisted-pair connections.

The SE140 is most commonly used to protect telecom equipment, such as routers, switches, and hubs, from lightning strikes and other electrical disturbances. Installing an SE140 can provide outstanding protection from dangerous electrical surges and high voltages, safeguarding against catastrophic damage and the associated costs.

SE140s are tested and certified to meet the standards of both telecom and industrial products. The devices are also designed for easy installation in single portal and chamber distribution cabinets. Thanks to the SE140\'s engineering and fabrication methods, technicians can quickly install the device without taking any additional steps.
