Gas Discharge Tubes Heavy Duty Delta Range RoHS SL1411A Series Two-terminal Gas Plasma Arrester Pb ® The Greentube™ SL1411A (Delta) Series Gas Plasma Arrester (improved gas discharge tube (GDT)) features is a highperformance transient voltage suppressor designed for heavyduty protection of telecom and industrial equipment. The Delta range offers high levels of performance and durability on fast-rising transients in the domain of 100 V/µS to 1 kV/µS, which are those most likely from induced lightning disturbances. The high surge rating of these devices makes them ideal for arduous service conditions and Outside Plant locations. The Delta range also features ultra low capacitance (typically 1 pF or less) and optimized internal geometry which provides low insertion loss at high frequencies, so are ideal for the protection of broadband equipment.
