Gas Discharge Tube Arresters (GDT) are an important part of electrical protection systems. They are used to protect equipment and systems from high voltage transients and surges caused by a number of external sources, including lightning. The 2093-120-SM-RPLF GDT is a particularly popular type of arrestor because of its compact design, small size, and ability to operate effectively in environmental conditions where temperatures may range from -40 to 90 °C.

When a voltage is applied to an arrester, which is greater than its rated voltage, it will begin to conduct, and this is known as conducting voltage. The 2093-120-SM-RPLF has a conducting voltage of 120 V and a breakdown voltage of 126 V. This means that it will be able to conduct current when the voltage across it rises to more than 120 V, and break down the connection when the voltage rises to more than 126 V.

The 2093-120-SM-RPLF GDT also includes built-in protection from excess current. This is known as its “let-through” current rating. The let-through rating of this arrester is 2.4 A. This rating means that it will be able to handle up to 2.4 A of overload current before it needs to be replaced. In addition, the 2093-120-SM-RPLF has a fast response time, meaning that it is able to conduct current as soon as the voltage rises to more than 120 V.

The 2093-120-SM-RPLF is designed to be installed in the distribution system, especially in off-grid applications. In these applications, the arrester is usually placed in a distribution box downstream from the point of connection to the public utility grid. This prevents the arrester from being affected by utility lines, and it also ensures that the arrester will be able to provide effective protection even during periods when the utility is not supplying power.

The 2093-120-SM-RPLF GDT works by limiting the amount of current that can be conducted by it. When an increased voltage is applied to the arrester, it will conduct current, but the amount of current conducted will be limited. This prevents a surge of excessive current from entering the system and damaging equipment. The protection afforded by the arrester is both visual and physical, since the arrester will discharge the current safely if the breakdown voltage is exceeded.

The 2093-120-SM-RPLF is also designed to self-heal after it has been used to conduct a surge of excessive current. This is known as its self-healing capability. The difference between a self-healing and a non-self-healing arrester is that the self-healing arrester will be able to reset itself after the surge of current is conducted. This means that the arrester can be used multiple times before it needs to be replaced.

In conclusion, the 2093-120-SM-RPLF GDT is a reliable and cost effective component for protecting equipment and systems in off-grid applications. It has a conducting voltage of 120 V, and when the voltage exceeds 126 V, the arrester will break down the connection. It also has a fast response time, ensuring that it can protect the system even during short-term spikes in voltage. Finally, the 2093-120-SM-RPLF arrester is self-healing, meaning that it can be used multiple times before needing to be replaced.
