: C22.2, No. 8 M1986
LR100413
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.
ț RAV-BXZ-3C:
This model is designed for use in three phase power
circuit applications.Combining multiple RAVs with
specially treated electrodes for greatly enhanced
noise immunity test and surge life, this model is
constructed in a unit-molded body.

ț Use of Surge Protectors:
Okaya Surge protectors in combination with Okaya
XYE series filter capacitors offer superb lightning
surge suppression. Capacitor XYE-104332 will
equalize excessive currents aiding the surge pro-
tector in absorbing the lightning surge. This parts
combination is equally effective against severe
noise.
Surge protectors can be connected to protect ma-
chines using 208/240VAC 3-phase power supplies.
The combination of the 3XYG series of high pulse
capacitors with the RAV-781BXZ-3C surge protec-
tor, is an effective countermeasure against exces-
sive surge and noise.
ț Noise MarginTest:
Noise margin testing usually requires the physical
disconnection of lightning surge protection
components. Such disconnection often is difficult,
and time consuming. Okaya’s RAV-BWZ-3C and
BXZ-3C series allows noise margin testing without
any such disconnection as they are designed to
withstand the rigors of testing.
