1. Introduction:

Gas Discharge Tubes (GDT) or direct current protective arresters are a type of electrical protection devices that are typically used to protect electric circuits from over voltage and over current transient phenomena. GDTs are often used in place of fuses and other forms of protection devices in order to limit the size of the current surge and consequently the voltage rise. The B88069X4900C103 is a type of GDT supplied by EPCOS, and is a form of surge arrester optimized for applications such as communication networks and in apparatus requiring safety class 1 or class 2 requirements. The B88069X4900C103 arrester characterizes itself by its robust design with enhanced characteristics against overvoltages, long lifetime and ease of operation due to its safe operation within the rated range even at high temperatures.

2. Application Field and Working Principle:

The B88069X4900C103 GDT arrester is intended for installation over current and overvoltage protection needs over fixed broadband connection networks such as telecommunication networks and cable TV. These networks often require protection against both lightning strikes as well as against higher electrostatic charges that travel through cables in order to prevent damage to any equipment connected to the line. By connecting the GDT arrester at a suitable point on the line between the network and the device, it will limit any high energy transient that is being carried by the cables to a suitable level. Emphasis is placed on the arrester\'s capability to respond fast and without damages to inflammable material due to the insulation of the element. This is done through its internal design that, in the normal operation range, dissipates any transient permanently. When lightning or other high energy transients occur the arrester conducts it away to the line while blocking the energy and allowing only a simple and safe voltage to pass. This effectively shields the devices connected to the line.

3. Technical Specifications:

The B88069X4900C103 GDT arrester is fully compliant with EN 61643-11 as well as VDE measures requirements and their characteristics ensure operation in any environment. This includes noise, severe electrical disturbances, overvoltages and lightning strikes. The B88069X4900C103 GDT arrester is also rated to handle up to 10KA current and up to 5kV voltage. The arrester is designed to be connected to lines of max 600V RMS AC, 400V DC, provided that its maximum ambient temperature of +70°C and the rated energy is not exceeded. The arrester is further equipped with a shell or enclosure which is fully UL 94V-0 approved.

4. Conclusion:

The B88069x4900C103 GDT arrester is an effective and reliable form of protection for communication networks and devices. Its optimized design and characteristics make it easy to use and its robust shell and enclosure provide additional protection against overvoltages and transient phenomena. The B88069X4900C103 GDT arrester is an effective solution to protect against both lightning strikes as well as any electrostatic charges that may travel through cables. With these features it is a well suited arrester to protect a variety of communication networks and devices.
