SL1021B350RG

Gas Discharge Tube Arresters (GDT) are electrical protectors designed to protect electrical systems from damage due to transient and extreme voltage changes. The SL1021B350RG is a type of GDT arrester that is designed to protect electrical systems from lightning surges, induced transients and other over-voltage conditions. It is a three-terminal device, typically used as a reverse-biased circuit breaker in low voltage applications.

The SL1021B350RG is composed of a gas filled chamber, metal electrodes, and a resistor. The gas filled chamber acts as a resistor which contains a variety of gases, including nitrogen, argon, and oxygen. This combination of gases results in an electrical breakdown when a certain threshold voltage is applied across the electrodes. The metal electrodes are used to detect and control the voltage across the gas tube, while the resistor regulates the breakdown voltage.

The working principle of the SL1021B350RG is fairly simple. When a sufficiently high voltage is applied across the electrodes, an arc is created, resulting in an electric current flow. The resistor limits the current and the gas within the tube extinguishes the arc. Once the voltage is lowered back to a safe level, the arrester automatically turns back on and re-establishes its protection.

The SL1021B350RG is typically used in low voltage applications, such as telecommunications, power distribution, and solar power applications. It is designed to protect systems against surges of up to 10,000 A in 10/1000 μs and has a tolerance of up to 20,000 A in 10/1000 μs. It also has a voltage rating of 350V.

The SL1021B350RG is a reliable and efficient GDT arrester. It is designed to provide protection from transient voltages and extreme voltage changes, preventing damage to electrical systems. As such, it is an important tool for electrical engineers and technicians for ensuring the proper functioning of electrical systems.
