Gas Discharge Tubes

SL1411A Series Two-terminal Gas Plasma Arrester

The Greentube™ SL1411A (Delta) Series Gas Plasma Arrester

(improved gas discharge tube (GDT)) features is a high-

performance transient voltage suppressor designed for heavy-

duty 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.
