Ceramic Arrester (Gas Discharge Tubes):

The Ceramic Gas Tube Arresters manufactured by Sankosha Corporation provide protection for personnel, equipment and circuitry from the abnormally high transient voltages which can surge limiting characteristics. When the abnormal voltage on a line reaches that defined level, sparkover (or breakdown) occurs within the gas tube arrested, the surge is redirected and people and equipment are protected.
