Gas Discharge Tube Arresters (GDT), also known as surge arresters, are types of equipment designed to protect electric circuits by shorting high-voltage spikes to ground. The SA2-7200-CLB-STD is an example of this type of protection device. It is designed to protect against over-voltage and current due to switching transients, lightning, and other sources of electrical transients.

The SA2-7200-CLB-STD consists of two series-connected GDTs, each in a ground connection. This module is designed for use in medium-voltage distribution systems, and it has a rated operational voltage of 6.9/13.8 kV. The device is approved for use in Ireland and carries the CE mark for quality assurance.

The SA2-7200-CLB-STD responds quickly to voltage surges, and it can limit the magnitude of the current to safe levels. The device also has a high voltage hold-off capability, meaning it can protect circuits from transients above the defined operating voltage level. It has also been tested and found to be very reliable and reliable in short circuit current limiting.

The protection mechanism of the SA2-7200-CLB-STD is a combination of mechanical and electrical design. The two series-connected GDTs act as arc-quenchers during high-voltage transients. At over-voltage, the nature of the electrical field created causes the air particles inside the GDTs to begin to ionize, allowing the charge to pass through the tube. The ionized air particles move quickly, and the emerging charge strikes the electrodes in the GDTs with a very fast response, limiting the magnitude of the current and turning it off quickly.

When the voltage and current features of the device are appropriately selected, the SA2-7200-CLB-STD operates as an extremely reliable lightning-protection device. It can handle high-voltage pulses and provide a high degree of safety to the protected devices. This device is suitable for industrial and commercial applications, and it also meets the requirements for residential applications.

The SA2-7200-CLB-STD is easy to install and features built-in test points which allow for easy troubleshooting. The device also provides convenience features such as zone switching, which enables the user to adjust the level of protection to the requirements of a given application. This flexibility makes the device the ideal choice for protecting circuits from transient overvoltages and currents.

The SA2-7200-CLB-STD is an exemplary GDT, and it provides reliable over-voltage and current protection from various sources of transient over-voltages and currents including lightning, switching transients, and other sources. Its combination of mechanical and electrical design, coupled with the convenience features, make it the ideal choice for protecting electric circuits.
