R·A·V-BWZ-2A
This model is designed specifically for use in AC
power line applications. This model uses specially
treated discharge electrodes for greatly enhanced
noise immunity test and surge life making it
optimum for the protection of single-phase power
supply circuits.

R·A·V-BXZ-2A
This model is designed specifically for use in
three-phase power circuit applications. Combing
multiple PAVs with specially treated electrodes for
greatly enhanced noise immunity test and surge life,
this model is constructed in a unit-molded body.
R·A·V-BYZ-2
This model is designed specifically for use in
three-phase power circuit applications.
It is
designed to protect against “normal mode” noise
transient surges.
When used in conjunction with the RAV-BXZ-2A,
it will furnish complete protection of equipment from
both Normal and Common mode transient voltage
surges.
