Gas Discharge Tube Arresters (GDT) are a critical component in power systems, designed to limit transient overvoltage events such as lightning strikes or arcing events. The CG32.5L is one such GDT device, which has been designed to provide protection for power distribution and industrial control systems. In this article, we will discuss the application field and working principle of the CG32.5L.

The CG32.5L is optimized for applications in conduits and loadcenter-style enclosures. It is suitable for use in those applications with a system voltage between 480Y/277V AC and 240V AC, as well as in 277V to 120V control systems. The device is designed to meet safety requirements and, as such, it is UL 1449 listed.

The CG32.5L has an integral arc resistor which shortens the duration of the overvoltage event, minimizing the risk of harm to personnel and property. The arc resistor also limits the flow of arcing current and helps protect downstream components such as circuit breakers and surge suppressors. The GDT also features a highly sensitive spark gap which provides reliable arcing protection. This spark gap is designed to trip off during an overvoltage event before arcing starts.

The CG32.5L operates based on the principle of a gas discharge tube. When an overvoltage occurs, the spark gap opens and the device is effectively rendered open-circuit. This prevents energy from flowing through and helps to protect the electrical system. In the event of an overvoltage, the spark gap also emits a spark, which helps to further dissipate the energy and reduce the risk of arcing.

The CG32.5L also features an additional arc resistor, which helps to further dissipate energy and reduce arc current. The arc resistor is designed to trip off when excessive currents are detected, providing further protection for downstream components. This feature helps to ensure that the device is suitable for use in even the most demanding applications.

The CG32.5L is a highly reliable and robust GDT device, capable of providing reliable protection even in the most extreme conditions. It is designed to be easy to install and maintain, ensuring that it is suitable for a variety of applications. In addition, the device can also be used in both indoor and outdoor applications, making it a versatile and cost-effective solution for GDT applications.

In summary, the CG32.5L is a Gas Discharge Tube Arrester specifically designed for use in the power distribution and industrial control systems. It is suitable for use in a range of applications with system voltages between 480Y/277V AC and 240V AC, and features an integral arc resistor, a spark gap, and an additional arc resistor for added protection. The device is a highly reliable and robust GDT, offering effective and dependable protection in both indoor and outdoor applications.
