Gas Discharge Tube (GDT) arresters are an essential part of protection systems. They are designed to protect electrical systems and are typically used in a variety of electrical, installation, and marine applications. GDTs have certain advantages over other forms of surge protection, such as their low maintenance and easy installation. In this article, we will discuss the application field and working principle of the CG2145LSSNTR.

The CG2145LSSNTR is designed for use in an ungrounded installation. It has a voltage rating of +/-1000V, a continuous operating voltage of 600V, a leakage current of 0.55mA, and a maximum current of 17.2A. Its maximum breaking capacity is 3000A and it has a minimum sparkover voltage of <920V. It is also designed with an flame-retardant plastic case and is RoHS compliant.

In terms of its application field, the CG2145LSSNTR is suitable for use in a wide range of power systems, including switchgear, rectifier bridges, AC/DC power supplies, buildings, and telecommunications. It is particularly well suited for use in low and medium voltage systems, as well as high voltage systems up to 1000V.

The CG2145LSSNTR works by using a gas discharge tube. When an overvoltage is detected, the gas in the tube is ionized, causing an arc to form within the tube. This arc absorbs the excess energy, preventing it from reaching the sensitive equipment that the GDT is protecting. When the overvoltage has been dissipated, the arc extinguishes and the GDT is ready to protect again.

The CG2145LSSNTR also provides protection against lightning surges, surges due to switching operations, and transient overvoltages caused by atmospheric disturbances or power line faults. It is also capable of discriminating between normal and faulted operation, meaning it can provide protection against both disturbances and faults.

The CG2145LSSNTR is designed to meet the highest standards of safety and performance. It is UL listed and CSA certified, and has been tested to withstand temperatures up to 125°C. It also includes a self-test function, which helps ensure that the GDT is functioning properly.

In conclusion, the CG2145LSSNTR is an excellent choice for use in a variety of applications, particularly in low and medium voltage power systems. Its ability to discriminate between normal and faulted operation, as well as its self-test function and wide operating temperature range, make it an ideal solution for those looking for reliable GDT protection.
