Gas Discharge Tube Arresters (GDT) are vital components used in electrical power systems for the purpose of protecting equipment and conductors from transient overvoltages caused by lightning and switching operations. As one of the most common types of GDT, the SL1024A250RF offers a wide range of applications and possesses a reliable working principle.

As a voltage surge protector, the SL1024A250RF is suitable for many applications, such as telecommunication systems, power systems, and electronic instrumentations. With lightning strike levels of 10*5kA 10/350us (B-level) and 2*5kA 8/20us (C-level), the arrestor provides excellent protection to connected equipment.

The SL1024A250RF is designed to protect connected equipment from voltage spikes and other electrical surges. It does this by diverting the surge current from the protected line to the ground. The internal design of the arrester houses two metal oxide varistors (MOVs), which act as linear nonlinear resistors. In normal operation, the special shape of these varistors prevents current from passing through the arrester. When a surge occurs, the MOVs start passing current through the arrester, reducing the voltage applied to the protected equipment.

Under normal operating conditions, the voltage across the GDT arrester remains low, and this keeps the MOVs in the off-state. When a transient voltage peak higher than the normal level is detected, the MOVs start to conduct current, thus reducing the voltage applied to the equipment. The arrestor then returns to its off-state once the transient voltage has subsided and the voltage across the MOVs returns to normal levels.

The SL1024A250RF has an insulation voltage of 250V, with an acoustic noise level of less than 40dB. It is also capable of passing a current load of up to 500mA, allowing it to handle higher surge currents without any damage to the MOVs. Lastly, its dielectric strength is 2400V/mm, ensuring a reliable operation even in harsh environments.

The SL1024A250RF is a reliable voltage surge protector and is suitable for a wide range of applications. Its robust construction, excellent performance, and low noise level makes it an ideal choice for use in power and telecommunication systems, as well as in electronic instrumentations.
