Gas Discharge Tube Arresters (GDT) have been developed as a means of providing protection from surges and transient voltage spikes in electrical systems. They are made up of a gas-filled tube with a first-level counter electrode, which acts as a shield against the quick, high-voltage surges that damage equipment. The GDT is connected to a circuit breaker or other device that is designed to cut off the power when a surge is detected.

2056-25-B2LF GDT is an over voltage automatic protector (also called gas discharge tube, GDT, spark gap, clip gap, elbow gap, etc.) designed for AC power system. It has no voltage limit, just continuously rises until the internal gas pressure is high enough to blow out. This feature ensures maximum protection against repetitive over voltage. This clip gap features a lead-free enclosure, that provides better insulation and reduces false triggering. It is designed to arrest lightning surge and other hazardous over voltages on both the line and ground sides of electrical installations, and is suitable for a wide range of commercial and industrial applications.

The working principle of 2056-25-B2LF GDT is straightforward, when the electrical system is subjected to an excessive surge, the clip gap is designed to blow out and discharge the electrical energy. The clip gap will absorb the electrical energy in the form of a current which passes through a rapidly evaporating conductor. The conductor will then form a plasma arc which is responsible for dissipating the excess energy.

Heating the metal conductor also causes the gas to expand and increase in pressure, resulting in an increased temperature within the arc and a decrease in arc current. This in turn causes the conductor to cool down and return to its normal state, while the gas returns to its normal pressure and the gap is re-closed. The cycle is repeated for each overvoltage, providing protection against further damage.

2056-25-B2LF GDT plays a critical role in safeguarding electrical systems from power outages and surges. It is a reliable device that can be used in a wide range of scenarios, ranging from commercial installations to home and industrial applications. It offers a adjustable level of protection, which allows users to customize the protection and response time depending on the application.

With 2056-25-B2LF GDT, the users are provided with the confidence and assurance that their electrical systems are protected from hazardous over voltages. The device is also cost effective and easy to install, making it a popular choice for many users.
