“ZNR” Transient/Surge Absorbers (Type SC)

“ZNR” Transient/Surge Absorbers (Type SC)
“ZNR” Transient/Surge Absorbers
Type :
SC
The ZNR Type SC protects power supply facilities,
communications equipment from steep lightning surges,
and it is a suitable product to incorporate it in a serge
protective device corresponding to the Japanese
Industrial Standards (JIS C 5381-1).
Features
● Very
large surge withstanding capability with a compact size
response to steep impulse voltage
● Low clamping voltage for better surge protection
● No follow-on current
● RoHS compliant
● Fast
Recommended Applications
● Power suppliers for OA, FA, telecommunication or industrial equipment
● Traffic or railroad systems
● Surge protection of automatic control devices for power distribution line
