Gas DischargeTube (GDT) Products

AC and CG3 Series

Description

Littelfuse AC series two-electrode line protectors

provide a high degree of surge protection in AC line

applications. The two models, AC120 and AC240

are designed for use with 120VAC and 240VAC lines

respectively. They are able to extinguish AC follow-on

currents of at least 200A.

Littelfuse CG3 two electrode high voltage (1.0 - 7.5

KV) devices are designed for surge protection and

high isolation applications, and for applications

for which bias voltages or signal levels of several

hundred volts are normally present.
