Gas Discharge Tube Arresters (GDT) can be used in a variety of applications, ranging from lightning protection for telecommunication to protection of control and other industrial circuits from transient surges. GTCA28-102M-P03 is a GDT device from Eaton’s series of Gas Discharge Tube Arresters. It is a surge protector that provides high performance protection against electrical transients. In this article we will be discussing the application field and working principles of the GTCA28-102M-P03 Gas Discharge Tube Arresters.

The GTCA28-102M-P03 is designed for a broad range of telecom applications. It is suitable for outdoor and indoor applications, such as ground-fault circuit interruptors, building protection systems, and lightning protection systems. It can be used to protect coaxial and twisted-pair cables used for DSL or other telecommunications applications. The device features surge rating of 40kA and discharge current rating of 100A, making it suitable for use in many applications.

The GTCA28-102M-P03 operates on the principle of transient overload current protection. This type of countermeasure uses an arrester device to attenuate the surge voltage. The GTCA28-102M-P03 has a high breakdown voltage of over 200V, which when exceeded by the surge voltage causes a spark gap between the electrodes of the GDT, resulting in a reduction of the surge energy. As the transient current verges on the breakdown voltage, the arrester device limits the current at a safe level. This provides effective protection against transient spikes and surges that can harm or damage sensitive components of a system. The device also features a peak impulse current rating of 10A, which further enhances the device’s surge protection capabilities.

The GTCA28-102M-P03 also provides lightning protection as it is capable of withstanding high transients such as lightning strokes. When a lightning stroke or power surge occurs, the GDT absorbs the surge energy, limiting the voltage to a safe level. This prevents damage to system components and other equipment connected to it. The device also has a high energy capability, withstanding multiple strikes. This ensures that the device can provide reliable protection against lightning and other transient events.

In summary, the GTCA28-102M-P03 is a versatile gas discharge tube arresters designed for a broad range of telecom applications. It features a high breakdown voltage and a peak impulse current rating of 10A, providing reliable protection against transient events such as lightning strokes and power surges. Additionally, the device can withstand multiple strikes, providing excellent protection against repeat event transients. By combining surge protection and lightning protection capabilities, the GTCA28-102M-P03 is the ideal solution for protecting sensitive telecom systems from transient events.
