Ceramic Gas Tube Surge Arrester

(Gas Discharge Tube or GDT)

Gas tube arresters protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients. Our surge protection devices have well defined surge-limiting characteristics enabling them to spark over (or breakdown) when the abnormal voltage on a line reaches a specific level. When spark over occurs in the GDT, the surge is redirected to earth.
