SL1021B420R

Gas Discharge Tube Arresters (GDT) are an important device used in electrical power systems to protect against lightning strikes, over-voltage transients and other dangerous and damaging currents. GDTs provide protection from damaging power surges and helps keep the electrical system operating safely. The SL1021B420R GDT is an ideal choice for applications requiring effective, reliable protection against lightning strikes and other over-voltage scenarios.

The SL1021B420R is a glass-encapsulated GDT with a high-performance silicon base. It uses a unique design which incorporates high-voltage, low-current, fast-breakdown technology. This technology allows the device to withstand overvoltage transients and spikes caused by lightning and other sources. Also, the design of the SL1021B420R provides superior thermal protection, which prevents the device from becoming the source of the surge. This thermal protection ensures that the device functions as intended, providing maximum protection to the power system.

The operating principle of the SL1021B420R Gas Discharge Tube Arrester is simple. When the voltage over the protective element exceeds the rated limit, a spark occurs, the spark gap in the device conducts the current until its voltage falls below the breakdown voltage. This voltage drops down, extinguishes the arc, and isolates the load from the superimposed voltage wave, thus providing the required protection.

The SL1021B420R GDT is designed specifically for applications requiring reliable, effective protection from lightning strikes and other over-voltage scenarios. It is ideal for high-voltage applications such as distribution and transmission lines as well as telecommunication lines. It is also commonly used in service entrance applications, process and motor control equipment, and lots more. It is CE certified and RoHS compliant.

The SL1021B420R Gas Discharge Tube Arrester is designed to provide reliable and effective protection for a wide range of applications. With its high-performance design and advanced features, it is an ideal choice for protecting power systems from surges caused by lightning and other sources. It is a cost-effective solution for adding protection to your electrical system.
