Gas Discharge Tube Arresters or GDTs are protective devices that prevent explosions and surge voltages in electrical circuits caused by lightning strikes. They contain two electrodes, a gas-filled tube, and a couple of electrodes. A triggered circuit is used to create a spark across the electrodes, which breaks down the gas between them. This creates a temporary bridge called an arc that is able to divert excess current away from the vulnerable circuit. The excess current is then safely redirected or dissipated, providing extra protection against electrical over-voltages.

The GTCR38-501M-Q10-FS is an advanced Gas Discharge Tube Arrester, designed to provide the utmost protection against power overvoltages and surges in sensitive electrical systems. It is engineered with a highly efficient Gas Discharge Tube and self-resetting Tri-Shield ARC Chambers, as well as an embedded Silicon Controlled Rectifier (SCR). The state-of-the-art design of the GTCR38-501M-Q10-FS makes it suitable for outdoor applications, such as wind farms and solar installations, as well as residential, industrial, and military applications where power protection is a high priority.

The working principle of the GTCR38-501M-Q10-FS is based on the well-known valve principle of gas discharge tube arresters. When an overvoltage occurs, the high voltage applied to the arrester triggers the electrostatic spark across the two electrodes, creating an arc between them. The arc then ionizes the gas in the tube, which serves as a valve and bridging the gap between the electrodes. This provides an electrical connection with very high impedance, acting as a ‘short’ to divert the overvoltage from the sensitive part of the circuit. The arc will eventually extinguish, re-establishing the original path for the overvoltage. The arrester is then ready for the next surge.

The GTCR38-501M-Q10-FS is designed to provide superior overvoltage protection to sensitive parts of the electrical system, including sensitive microprocessors, semiconductor panels, and other components in critical control systems. It is designed to ensure that the electrical system is protected from a wide range of potential electrical surge events. The advanced Gas Discharge Tube Arrester technology incorporated into the GTCR38-501M-Q10-FS allows for extreme low levels of luminescence, and very effective initial spark quenching. This combination of technologies helps to ensure optimal protection from electrical surges and power overvoltages, while avoiding unnecessary and hazardous sparking.

The GTCR38-501M-Q10-FS is engineered with an integrated Silicon Controlled Rectifier (SCR) which serves as both an isolator and an arc quencher for fast protection. This SCR technology ensures the highest level of protection available when dealing with electrical overvoltages, while providing a fast response time that can be as low as 6.5 μs. The advanced Silicon SCR also features an integrated feedback loop, allowing it to continually monitor the operation and performance level of the arrester. This extra level of protection greatly reduces the possibility of damage to the sensitive components that is typically associated with electrical overvoltages.

All these features make the GTCR38-501M-Q10-FS the perfect solution for any application where reliable protection from electrical overvoltages and surges is essential. Its advanced technology and design make it suitable for a wide range of industrial, military, and residential applications. Furthermore, the combination of Gas Discharge Tube and Silicon Controlled Rectifier technology make it one of the most reliable Gas Discharge Tube Arresters on the market today.
