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 - 75
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.
