SURGE ABSORBER
RA Series
• RA-V7
Safety Agency : Standard
The RA-V7 Series utilizes micro-gap discharge
technology, thus demonstrating extremely fast
response characteristics in dark ambient conditions
without the use of radioactive isotopes.

Applied as indirect lightning surge protection in the
power line of equipment, this model is used with a
series connected MOV between line and ground in
the power line.

FEATURES:
• Fast response time (see V-T Chart)
• This Surge Absorber is Bi-polar and will fail
open if surge withstand capability is exceeded.
• Inter-terminal capacitance is extremely small,
resulting in little influence on electronic
circuits.
• High Insulation Resistance (1x109h min.)
• Excellent Surge withstand capability
(300 times at 100Amp, 8x20µs.)
• Small size for compact circuit design.
• Available taped for auto insertion.
Add “Y” to model number.
(RA-242M-V7-Y)
It may also be used within electronic circuits to
protect from destructive impulse current while still
permitting “Voltage Withstand Testing” without
having to remove the RA-V7.
