GTCA28-402M-P01

Gas Discharge Tube Arresters (GDT)

A gas discharge tube arrestor (GDT) is a special type of surge arrester used in electrical installations to protect against transient overvoltages. The GDT is designed to allow a very high current to pass through it very quickly which serves to dissipate the energy of a surge and limit the peak voltage that passes through to the equipment.

The GDT is made up of two or more electrodes in a non-metallic container. When a surge or overvoltage occurs, the current flow causes the gas within the container to ionize and become conductive. This allows a large current to flow quickly and transiently which is then dissipated as heat and light before it can pass onto the system. This reduces the surge amplitude and limits the peak voltage to an acceptable level before the surge can pass onto the protected system.

The GTCA28-402M-P01 is a type of GDT which is specifically designed for applications such as telecommunications, low voltage electrical systems, and UPS systems. It is certified for use by the IEC 61643-1 Standard which defines the performance requirements for surge protective devices used in these applications. The GTCA28-402M-P01 is rated for 35kV/2kA with a maximum continuous operating voltage of 28V, a standby voltage of 24V, and an operating temperature range of -40 C to +80 C.

The working principle of the GTCA28-402M-P01 GDT is fairly simple but very effective. When a surge or overvoltage occurs, the gas within the container ionizes and becomes conductive. This allows a high current to flow quickly and transiently which dissipates the energy of the surge and limits the peak voltage that passes through to the protected system.

The GTCA28-402M-P01 is an effective and reliable surge arrester that can provide protection for telecom, low voltage electrical, and UPS systems against transient overvoltages. It has a high rating for surge current and voltage that is certified by the IEC 61643-1 Standard and features an operating temperature range of -40 C to +80 C. The principle of operation is straightforward and simple but the device is highly effective in preventing damage caused to systems due to transient overvoltages.

In summary, the GTCA28-402M-P01 is a reliable surge arrester that provides effective protection against transient overvoltages. The device is certified according to the IEC 61643-1 Standard for use in telecom, low voltage electrical, and UPS systems. The device works by allowing a high current to flow quickly through the ionized gas within the container to dissipate the energy of a surge and limit the peak voltage that passes through to the equipment.
