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.
