AC and CG3 Series Suppressors
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.
