The CV+ series of transient surge suppressors is the extended version of CV
disc shaped varistors. The CV+ series consists of 7 mm, 10 mm, 14 mm, 20 mm
and 23mm sized varistors of extremely high current and energy capabilities.
They provide an increased level of protection necessary for the transients
expected in telecommunication and AC power networks. The AC operating
voltage of these varistors ranges from 60 V to 550 V.
